/**
An instance of `Ember.Application` is the starting point for every Ember
application. It helps to instantiate, initialize and coordinate the many
objects that make up your app.
Each Ember app has one and only one `Ember.Application` object. In fact, the
very first thing you should do in your application is create the instance:
```javascript
window.App = Ember.Application.create();
```
Typically, the application object is the only global variable. All other
classes in your app should be properties on the `Ember.Application` instance,
which highlights its first role: a global namespace.
For example, if you define a view class, it might look like this:
```javascript
App.MyView = Ember.View.extend();
```
By default, calling `Ember.Application.create()` will automatically initialize
your application by calling the `Ember.Application.initialize()` method. If
you need to delay initialization, you can call your app's `deferReadiness()`
method. When you are ready for your app to be initialized, call its
`advanceReadiness()` method.
You can define a `ready` method on the `Ember.Application` instance, which
will be run by Ember when the application is initialized.
Because `Ember.Application` inherits from `Ember.Namespace`, any classes
you create will have useful string representations when calling `toString()`.
See the `Ember.Namespace` documentation for more information.
While you can think of your `Ember.Application` as a container that holds the
other classes in your application, there are several other responsibilities
going on under-the-hood that you may want to understand.
### Event Delegation
Ember uses a technique called _event delegation_. This allows the framework
to set up a global, shared event listener instead of requiring each view to
do it manually. For example, instead of each view registering its own
`mousedown` listener on its associated element, Ember sets up a `mousedown`
listener on the `body`.
If a `mousedown` event occurs, Ember will look at the target of the event and
start walking up the DOM node tree, finding corresponding views and invoking
their `mouseDown` method as it goes.
`Ember.Application` has a number of default events that it listens for, as
well as a mapping from lowercase events to camel-cased view method names. For
example, the `keypress` event causes the `keyPress` method on the view to be
called, the `dblclick` event causes `doubleClick` to be called, and so on.
If there is a bubbling browser event that Ember does not listen for by
default, you can specify custom events and their corresponding view method
names by setting the application's `customEvents` property:
```javascript
App = Ember.Application.create({
customEvents: {
// add support for the paste event
paste: "paste"
}
});
```
By default, the application sets up these event listeners on the document
body. However, in cases where you are embedding an Ember application inside
an existing page, you may want it to set up the listeners on an element
inside the body.
For example, if only events inside a DOM element with the ID of `ember-app`
should be delegated, set your application's `rootElement` property:
```javascript
window.App = Ember.Application.create({
rootElement: '#ember-app'
});
```
The `rootElement` can be either a DOM element or a jQuery-compatible selector
string. Note that *views appended to the DOM outside the root element will
not receive events.* If you specify a custom root element, make sure you only
append views inside it!
To learn more about the advantages of event delegation and the Ember view
layer, and a list of the event listeners that are setup by default, visit the
[Ember View Layer guide](http://emberjs.com/guides/understanding-ember/the-view-layer/#toc_event-delegation).
### Initializers
Libraries on top of Ember can add initializers, like so:
```javascript
Ember.Application.initializer({
name: 'api-adapter',
initialize: function(container, application) {
application.register('api-adapter:main', ApiAdapter);
}
});
```
Initializers provide an opportunity to access the container, which
organizes the different components of an Ember application. Additionally
they provide a chance to access the instantiated application. Beyond
being used for libraries, initializers are also a great way to organize
dependency injection or setup in your own application.
### Routing
In addition to creating your application's router, `Ember.Application` is
also responsible for telling the router when to start routing. Transitions
between routes can be logged with the `LOG_TRANSITIONS` flag, and more
detailed intra-transition logging can be logged with
the `LOG_TRANSITIONS_INTERNAL` flag:
```javascript
window.App = Ember.Application.create({
LOG_TRANSITIONS: true, // basic logging of successful transitions
LOG_TRANSITIONS_INTERNAL: true // detailed logging of all routing steps
});
```
By default, the router will begin trying to translate the current URL into
application state once the browser emits the `DOMContentReady` event. If you
need to defer routing, you can call the application's `deferReadiness()`
method. Once routing can begin, call the `advanceReadiness()` method.
If there is any setup required before routing begins, you can implement a
`ready()` method on your app that will be invoked immediately before routing
begins.
```

instances.
If you would like additional bubbling events to be delegated to your
views, set your `Ember.Application`'s `customEvents` property
to a hash containing the DOM event name as the key and the
corresponding view method name as the value. For example:
```javascript
App = Ember.Application.create({
customEvents: {
// add support for the paste event
paste: "paste"
}
});
```

/**
Registers a factory that can be used for dependency injection (with
`App.inject`) or for service lookup. Each factory is registered with
a full name including two parts: `type:name`.
A simple example:
```javascript
var App = Ember.Application.create();
App.Orange = Ember.Object.extend();
App.register('fruit:favorite', App.Orange);
```
Ember will resolve factories from the `App` namespace automatically.
For example `App.CarsController` will be discovered and returned if
an application requests `controller:cars`.
An example of registering a controller with a non-standard name:
```javascript
var App = Ember.Application.create(),
Session = Ember.Controller.extend();
App.register('controller:session', Session);
// The Session controller can now be treated like a normal controller,
// despite its non-standard name.
App.ApplicationController = Ember.Controller.extend({
needs: ['session']
});
```
Registered factories are **instantiated** by having `create`
called on them. Additionally they are **singletons**, each time
they are looked up they return the same instance.
Some examples modifying that default behavior:
```javascript
var App = Ember.Application.create();
App.Person = Ember.Object.extend();
App.Orange = Ember.Object.extend();
App.Email = Ember.Object.extend();
App.session = Ember.Object.create();
App.register('model:user', App.Person, {singleton: false });
App.register('fruit:favorite', App.Orange);
App.register('communication:main', App.Email, {singleton: false});
App.register('session', App.session, {instantiate: false});
```
@method register
@param fullName {String} type:name (e.g., 'model:user')
@param factory {Function} (e.g., App.Person)
@param options {Object} (optional) disable instantiation or singleton usage
**/
register: function() {
var container = this.__container__;
container.register.apply(container, arguments);
},
/**
Define a dependency injection onto a specific factory or all factories
of a type.
When Ember instantiates a controller, view, or other framework component
it can attach a dependency to that component. This is often used to
provide services to a set of framework components.
An example of providing a session object to all controllers:
```javascript
var App = Ember.Application.create(),
Session = Ember.Object.extend({ isAuthenticated: false });
// A factory must be registered before it can be injected
App.register('session:main', Session);
// Inject 'session:main' onto all factories of the type 'controller'
// with the name 'session'
App.inject('controller', 'session', 'session:main');
App.IndexController = Ember.Controller.extend({
isLoggedIn: Ember.computed.alias('session.isAuthenticated')
});
```
Injections can also be performed on specific factories.
```javascript
App.inject(<full_name or type>, <property name>, <full_name>)
App.inject('route', 'source', 'source:main')
App.inject('route:application', 'email', 'model:email')
```
It is important to note that injections can only be performed on
classes that are instantiated by Ember itself. Instantiating a class
directly (via `create` or `new`) bypasses the dependency injection
system.
Ember-Data instantiates its models in a unique manner, and consequently
injections onto models (or all models) will not work as expected. Injections
on models can be enabled by setting `Ember.MODEL_FACTORY_INJECTIONS`
to `true`.
@method inject

Reset the application. This is typically used only in tests. It cleans up
the application in the following order:
1. Deactivate existing routes
2. Destroy all objects in the container
3. Create a new application container

Typical Example:
```javascript
var App;
run(function() {
App = Ember.Application.create();

}
});
test("first test", function() {

```
Advanced Example:
Occasionally you may want to prevent the app from initializing during
setup. This could enable extra configuration, or enable asserting prior
to the app becoming ready.
```javascript
var App;
run(function() {
App = Ember.Application.create();
});
module("acceptance test", {
setup: function() {
run(function() {
App.reset();
App.deferReadiness();
});
}

/**
The DefaultResolver defines the default lookup rules to resolve
container lookups before consulting the container for registered
items:
* templates are looked up on `Ember.TEMPLATES`
* other names are looked up on the application after converting
the name. For example, `controller:post` looks up
`App.PostController` by default.
* there are some nuances (see examples below)
### How Resolving Works
The container calls this object's `resolve` method with the
`fullName` argument.
It first parses the fullName into an object using `parseName`.
Then it checks for the presence of a type-specific instance
method of the form `resolve[Type]` and calls it if it exists.
For example if it was resolving 'template:post', it would call
the `resolveTemplate` method.
Its last resort is to call the `resolveOther` method.
The methods of this object are designed to be easy to override
in a subclass. For example, you could enhance how a template
is resolved like so:
```javascript
App = Ember.Application.create({
Resolver: Ember.DefaultResolver.extend({
resolveTemplate: function(parsedName) {
var resolvedTemplate = this._super(parsedName);
if (resolvedTemplate) { return resolvedTemplate; }
return Ember.TEMPLATES['not_found'];
}
})
});
```
Some examples of how names are resolved:
```
'template:post' //=> Ember.TEMPLATES['post']
'template:posts/byline' //=> Ember.TEMPLATES['posts/byline']
'template:posts.byline' //=> Ember.TEMPLATES['posts/byline']
'template:blogPost' //=> Ember.TEMPLATES['blogPost']
// OR
// Ember.TEMPLATES['blog_post']
'controller:post' //=> App.PostController
'controller:posts.index' //=> App.PostsIndexController
'controller:blog/post' //=> Blog.PostController
'controller:basic' //=> Ember.Controller
'route:post' //=> App.PostRoute
'route:posts.index' //=> App.PostsIndexRoute
'route:blog/post' //=> Blog.PostRoute
'route:basic' //=> Ember.Route
'view:post' //=> App.PostView
'view:posts.index' //=> App.PostsIndexView
'view:blog/post' //=> Blog.PostView
'view:basic' //=> Ember.View
'foo:post' //=> App.PostFoo
'model:post' //=> App.Post
```

Register a bound helper or custom view helper.
## Simple bound helper example
```javascript

});
```
The above bound helper can be used inside of templates as follows:
```handlebars
{{capitalize name}}
```
In this case, when the `name` property of the template's context changes,
the rendered value of the helper will update to reflect this change.
For more examples of bound helpers, see documentation for
`Ember.Handlebars.registerBoundHelper`.
## Custom view helper example
Assuming a view subclass named `App.CalendarView` were defined, a helper
for rendering instances of this view could be registered as follows:
```javascript
Ember.Handlebars.helper('calendar', App.CalendarView):
```
The above bound helper can be used inside of templates as follows:
```handlebars
{{calendar}}
```
Which is functionally equivalent to:
```handlebars
{{view App.CalendarView}}
```
Options in the helper will be passed to the view in exactly the same
manner as with the `view` helper.

/**
The `{{input}}` helper inserts an HTML `<input>` tag into the template,
with a `type` value of either `text` or `checkbox`. If no `type` is provided,
`text` will be the default value applied. The attributes of `{{input}}`
match those of the native HTML tag as closely as possible for these two types.
## Use as text field
An `{{input}}` with no `type` or a `type` of `text` will render an HTML text input.
The following HTML attributes can be set via the helper:
<table>
<tr><td>`readonly`</td><td>`required`</td><td>`autofocus`</td></tr>
<tr><td>`value`</td><td>`placeholder`</td><td>`disabled`</td></tr>
<tr><td>`size`</td><td>`tabindex`</td><td>`maxlength`</td></tr>
<tr><td>`name`</td><td>`min`</td><td>`max`</td></tr>
<tr><td>`pattern`</td><td>`accept`</td><td>`autocomplete`</td></tr>
<tr><td>`autosave`</td><td>`formaction`</td><td>`formenctype`</td></tr>
<tr><td>`formmethod`</td><td>`formnovalidate`</td><td>`formtarget`</td></tr>
<tr><td>`height`</td><td>`inputmode`</td><td>`multiple`</td></tr>
<tr><td>`step`</td><td>`width`</td><td>`form`</td></tr>
<tr><td>`selectionDirection`</td><td>`spellcheck`</td><td>&nbsp;</td></tr>
</table>
When set to a quoted string, these values will be directly applied to the HTML
element. When left unquoted, these values will be bound to a property on the
template's current rendering context (most typically a controller instance).
## Unbound:
```handlebars
{{input value="http://www.facebook.com"}}
```
```html
<input type="text" value="http://www.facebook.com"/>
```
## Bound:
```javascript
App.ApplicationController = Ember.Controller.extend({
firstName: "Stanley",
entryNotAllowed: true
});
```
```handlebars
{{input type="text" value=firstName disabled=entryNotAllowed size="50"}}
```
```html
<input type="text" value="Stanley" disabled="disabled" size="50"/>
```
## Extension
Internally, `{{input type="text"}}` creates an instance of `Ember.TextField`, passing
arguments from the helper to `Ember.TextField`'s `create` method. You can extend the
capabilities of text inputs in your applications by reopening this class. For example,
if you are building a Bootstrap project where `data-*` attributes are used, you
can add one to the `TextField`'s `attributeBindings` property:
```javascript
Ember.TextField.reopen({
attributeBindings: ['data-error']
});
```
Keep in mind when writing `Ember.TextField` subclasses that `Ember.TextField`
itself extends `Ember.Component`, meaning that it does NOT inherit
the `controller` of the parent view.
See more about [Ember components](api/classes/Ember.Component.html)
## Use as checkbox
An `{{input}}` with a `type` of `checkbox` will render an HTML checkbox input.
The following HTML attributes can be set via the helper:
* `checked`
* `disabled`
* `tabindex`
* `indeterminate`
* `name`
* `autofocus`
* `form`
When set to a quoted string, these values will be directly applied to the HTML
element. When left unquoted, these values will be bound to a property on the
template's current rendering context (most typically a controller instance).
## Unbound:
```handlebars
{{input type="checkbox" name="isAdmin"}}
```
```html
<input type="checkbox" name="isAdmin" />
```
## Bound:
```javascript
App.ApplicationController = Ember.Controller.extend({
isAdmin: true
});
```
```handlebars
{{input type="checkbox" checked=isAdmin }}
```
```html
<input type="checkbox" checked="checked" />
```
## Extension
Internally, `{{input type="checkbox"}}` creates an instance of `Ember.Checkbox`, passing
arguments from the helper to `Ember.Checkbox`'s `create` method. You can extend the
capablilties of checkbox inputs in your applications by reopening this class. For example,
if you wanted to add a css class to all checkboxes in your application:
```javascript
Ember.Checkbox.reopen({
classNames: ['my-app-checkbox']
});
```

__exports__.inputHelper = inputHelper;/**
`{{textarea}}` inserts a new instance of `<textarea>` tag into the template.
The attributes of `{{textarea}}` match those of the native HTML tags as
closely as possible.
The following HTML attributes can be set:
* `value`
* `name`
* `rows`
* `cols`
* `placeholder`
* `disabled`
* `maxlength`
* `tabindex`
* `selectionEnd`
* `selectionStart`
* `selectionDirection`
* `wrap`
* `readonly`
* `autofocus`
* `form`
* `spellcheck`
* `required`
When set to a quoted string, these value will be directly applied to the HTML
element. When left unquoted, these values will be bound to a property on the
template's current rendering context (most typically a controller instance).
Unbound:
```handlebars
{{textarea value="Lots of static text that ISN'T bound"}}
```
Would result in the following HTML:
```html
<textarea class="ember-text-area">
Lots of static text that ISN'T bound
</textarea>
```
Bound:
In the following example, the `writtenWords` property on `App.ApplicationController`
will be updated live as the user types 'Lots of text that IS bound' into
the text area of their browser's window.
```javascript
App.ApplicationController = Ember.Controller.extend({
writtenWords: "Lots of text that IS bound"
});
```
```handlebars
{{textarea value=writtenWords}}
```
Would result in the following HTML:
```html
<textarea class="ember-text-area">
Lots of text that IS bound
</textarea>
```
If you wanted a one way binding between the text area and a div tag
somewhere else on your screen, you could use `Ember.computed.oneWay`:
```javascript
App.ApplicationController = Ember.Controller.extend({
writtenWords: "Lots of text that IS bound",
outputWrittenWords: Ember.computed.oneWay("writtenWords")
});
```
```handlebars
{{textarea value=writtenWords}}
<div>
{{outputWrittenWords}}
</div>
```
Would result in the following HTML:
```html
<textarea class="ember-text-area">
Lots of text that IS bound
</textarea>
<-- the following div will be updated in real time as you type -->
<div>
Lots of text that IS bound
</div>
```
Finally, this example really shows the power and ease of Ember when two
properties are bound to eachother via `Ember.computed.alias`. Type into
either text area box and they'll both stay in sync. Note that
`Ember.computed.alias` costs more in terms of performance, so only use it when
your really binding in both directions:
```javascript
App.ApplicationController = Ember.Controller.extend({
writtenWords: "Lots of text that IS bound",
twoWayWrittenWords: Ember.computed.alias("writtenWords")
});
```
```handlebars
{{textarea value=writtenWords}}
{{textarea value=twoWayWrittenWords}}
```
```html
<textarea id="ember1" class="ember-text-area">
Lots of text that IS bound
</textarea>
<-- both updated in real time -->
<textarea id="ember2" class="ember-text-area">
Lots of text that IS bound
</textarea>
```
## Extension
Internally, `{{textarea}}` creates an instance of `Ember.TextArea`, passing
arguments from the helper to `Ember.TextArea`'s `create` method. You can
extend the capabilities of text areas in your application by reopening this
class. For example, if you are building a Bootstrap project where `data-*`
attributes are used, you can globally add support for a `data-*` attribute
on all `{{textarea}}`s' in your app by reopening `Ember.TextArea` or
`Ember.TextSupport` and adding it to the `attributeBindings` concatenated
property:
```javascript
Ember.TextArea.reopen({
attributeBindings: ['data-error']
});
```
Keep in mind when writing `Ember.TextArea` subclasses that `Ember.TextArea`
itself extends `Ember.Component`, meaning that it does NOT inherit
the `controller` of the parent view.

## Direct manipulation of `checked`
The `checked` attribute of an `Ember.Checkbox` object should always be set
through the Ember object or by interacting with its rendered element
representation via the mouse, keyboard, or touch. Updating the value of the
checkbox via jQuery will result in the checked value of the object and its
element losing synchronization.

/**
The `Ember.Select` view class renders a
[select](https://developer.mozilla.org/en/HTML/Element/select) HTML element,
allowing the user to choose from a list of options.
The text and `value` property of each `<option>` element within the
`<select>` element are populated from the objects in the `Element.Select`'s
`content` property. The underlying data object of the selected `<option>` is
stored in the `Element.Select`'s `value` property.
## The Content Property (array of strings)
The simplest version of an `Ember.Select` takes an array of strings as its
`content` property. The string will be used as both the `value` property and
the inner text of each `<option>` element inside the rendered `<select>`.
Example:
```javascript
App.ApplicationController = Ember.ObjectController.extend({
names: ["Yehuda", "Tom"]
});
```
```handlebars
{{view Ember.Select content=names}}
```
Would result in the following HTML:
```html
<select class="ember-select">
<option value="Yehuda">Yehuda</option>
<option value="Tom">Tom</option>
</select>
```
You can control which `<option>` is selected through the `Ember.Select`'s
`value` property:
```javascript
App.ApplicationController = Ember.ObjectController.extend({
selectedName: 'Tom',
names: ["Yehuda", "Tom"]
});
```
```handlebars
{{view Ember.Select
content=names
value=selectedName
}}
```
Would result in the following HTML with the `<option>` for 'Tom' selected:
```html
<select class="ember-select">
<option value="Yehuda">Yehuda</option>
<option value="Tom" selected="selected">Tom</option>
</select>
```
A user interacting with the rendered `<select>` to choose "Yehuda" would
update the value of `selectedName` to "Yehuda".
## The Content Property (array of Objects)
An `Ember.Select` can also take an array of JavaScript or Ember objects as
its `content` property.
When using objects you need to tell the `Ember.Select` which property should
be accessed on each object to supply the `value` attribute of the `<option>`
and which property should be used to supply the element text.
The `optionValuePath` option is used to specify the path on each object to
the desired property for the `value` attribute. The `optionLabelPath`
specifies the path on each object to the desired property for the
element's text. Both paths must reference each object itself as `content`:
```javascript
App.ApplicationController = Ember.ObjectController.extend({
programmers: [
{firstName: "Yehuda", id: 1},
{firstName: "Tom", id: 2}
]
});
```
```handlebars
{{view Ember.Select
content=programmers
optionValuePath="content.id"
optionLabelPath="content.firstName"}}
```
Would result in the following HTML:
```html
<select class="ember-select">
<option value="1">Yehuda</option>
<option value="2">Tom</option>
</select>
```
The `value` attribute of the selected `<option>` within an `Ember.Select`
can be bound to a property on another object:
```javascript
App.ApplicationController = Ember.ObjectController.extend({
programmers: [
{firstName: "Yehuda", id: 1},
{firstName: "Tom", id: 2}
],
currentProgrammer: {
id: 2
}
});
```
```handlebars
{{view Ember.Select
content=programmers
optionValuePath="content.id"
optionLabelPath="content.firstName"
value=currentProgrammer.id}}
```
Would result in the following HTML with a selected option:
```html
<select class="ember-select">
<option value="1">Yehuda</option>
<option value="2" selected="selected">Tom</option>
</select>
```
Interacting with the rendered element by selecting the first option
('Yehuda') will update the `id` of `currentProgrammer`
to match the `value` property of the newly selected `<option>`.
Alternatively, you can control selection through the underlying objects
used to render each object by binding the `selection` option. When the selected
`<option>` is changed, the property path provided to `selection`
will be updated to match the content object of the rendered `<option>`
element:
```javascript
var yehuda = {firstName: "Yehuda", id: 1, bff4eva: 'tom'}
var tom = {firstName: "Tom", id: 2, bff4eva: 'yehuda'};
App.ApplicationController = Ember.ObjectController.extend({
selectedPerson: tom,
programmers: [
yehuda,
tom
]
});
```
```handlebars
{{view Ember.Select
content=programmers
optionValuePath="content.id"
optionLabelPath="content.firstName"
selection=selectedPerson}}
```
Would result in the following HTML with a selected option:
```html
<select class="ember-select">
<option value="1">Yehuda</option>
<option value="2" selected="selected">Tom</option>
</select>
```
Interacting with the rendered element by selecting the first option
('Yehuda') will update the `selectedPerson` to match the object of
the newly selected `<option>`. In this case it is the first object
in the `programmers`
## Supplying a Prompt
A `null` value for the `Ember.Select`'s `value` or `selection` property
results in there being no `<option>` with a `selected` attribute:
```javascript
App.ApplicationController = Ember.ObjectController.extend({
selectedProgrammer: null,
programmers: [
"Yehuda",
"Tom"
]
});
```
``` handlebars
{{view Ember.Select
content=programmers
value=selectedProgrammer
}}
```
Would result in the following HTML:
```html
<select class="ember-select">
<option value="Yehuda">Yehuda</option>
<option value="Tom">Tom</option>
</select>
```
Although `selectedProgrammer` is `null` and no `<option>`
has a `selected` attribute the rendered HTML will display the
first item as though it were selected. You can supply a string
value for the `Ember.Select` to display when there is no selection
with the `prompt` option:
```javascript
App.ApplicationController = Ember.ObjectController.extend({
selectedProgrammer: null,
programmers: [
"Yehuda",
"Tom"
]
});
```
```handlebars
{{view Ember.Select
content=programmers
value=selectedProgrammer
prompt="Please select a name"
}}
```
Would result in the following HTML:
```html
<select class="ember-select">
<option>Please select a name</option>
<option value="Yehuda">Yehuda</option>
<option value="Tom">Tom</option>
</select>
```

Register a bound handlebars helper. Bound helpers behave similarly to regular
handlebars helpers, with the added ability to re-render when the underlying data
changes.
## Simple example
```javascript
Ember.Handlebars.registerBoundHelper('capitalize', function(value) {
return Ember.String.capitalize(value);
});
```
The above bound helper can be used inside of templates as follows:
```handlebars
{{capitalize name}}
```
In this case, when the `name` property of the template's context changes,
the rendered value of the helper will update to reflect this change.
## Example with options
Like normal handlebars helpers, bound helpers have access to the options
passed into the helper call.
```javascript
Ember.Handlebars.registerBoundHelper('repeat', function(value, options) {
var count = options.hash.count;
var a = [];
while(a.length < count) {
a.push(value);
}
return a.join('');
});
```
This helper could be used in a template as follows:
```handlebars
{{repeat text count=3}}
```
## Example with bound options
Bound hash options are also supported. Example:
```handlebars
{{repeat text count=numRepeats}}
```
In this example, count will be bound to the value of
the `numRepeats` property on the context. If that property
changes, the helper will be re-rendered.
## Example with extra dependencies
The `Ember.Handlebars.registerBoundHelper` method takes a variable length
third parameter which indicates extra dependencies on the passed in value.
This allows the handlebars helper to update when these dependencies change.
```javascript
Ember.Handlebars.registerBoundHelper('capitalizeName', function(value) {
return value.get('name').toUpperCase();
}, 'name');
```
## Example with multiple bound properties
`Ember.Handlebars.registerBoundHelper` supports binding to
multiple properties, e.g.:
```javascript
Ember.Handlebars.registerBoundHelper('concatenate', function() {
var values = Array.prototype.slice.call(arguments, 0, -1);
return values.join('||');
});
```
Which allows for template syntax such as `{{concatenate prop1 prop2}}` or
`{{concatenate prop1 prop2 prop3}}`. If any of the properties change,
the helper will re-render. Note that dependency keys cannot be
using in conjunction with multi-property helpers, since it is ambiguous
which property the dependent keys would belong to.
## Use with unbound helper
The `{{unbound}}` helper can be used with bound helper invocations
to render them in their unbound form, e.g.
```handlebars
{{unbound capitalize name}}
```
In this example, if the name property changes, the helper
will not re-render.
## Use with blocks not supported
Bound helpers do not support use with Handlebars blocks or
the addition of child views of any kind.

In the above example, if the helper function hadn't been wrapped in

`bind` can be used to display a value, then update that value if it

at the specified path. If it changes, it will update the value in DOM. Note
that if you need to support IE7 and IE8 you must modify the model objects

relies on Ember's KVO system. For all other browsers this will be handled for

/**
Use the `{{with}}` helper when you want to scope context. Take the following code as an example:
```handlebars
<h5>{{user.name}}</h5>
<div class="role">
<h6>{{user.role.label}}</h6>
<span class="role-id">{{user.role.id}}</span>
<p class="role-desc">{{user.role.description}}</p>
</div>
```
`{{with}}` can be our best friend in these cases,
instead of writing `user.role.*` over and over, we use `{{#with user.role}}`.
Now the context within the `{{#with}} .. {{/with}}` block is `user.role` so you can do the following:
```handlebars
<h5>{{user.name}}</h5>
<div class="role">
{{#with user.role}}
<h6>{{label}}</h6>
<span class="role-id">{{id}}</span>
<p class="role-desc">{{description}}</p>
{{/with}}
</div>
```
### `as` operator
This operator aliases the scope to a new name. It's helpful for semantic clarity and to retain
default scope or to reference from another `{{with}}` block.
```handlebars
// posts might not be
{{#with user.posts as blogPosts}}
<div class="notice">
There are {{blogPosts.length}} blog posts written by {{user.name}}.
</div>
{{#each post in blogPosts}}
<li>{{post.title}}</li>
{{/each}}
{{/with}}
```
Without the `as` operator, it would be impossible to reference `user.name` in the example above.
NOTE: The alias should not reuse a name from the bound property path.
For example: `{{#with foo.bar as foo}}` is not supported because it attempts to alias using
the first part of the property path, `foo`. Instead, use `{{#with foo.bar as baz}}`.
### `controller` option
Adding `controller='something'` instructs the `{{with}}` helper to create and use an instance of
the specified controller with the new context as its content.
This is very similar to using an `itemController` option with the `{{each}}` helper.
```handlebars
{{#with users.posts controller='userBlogPosts'}}
{{!- The current context is wrapped in our controller instance }}
{{/with}}
```
In the above example, the template provided to the `{{with}}` block is now wrapped in the
`userBlogPost` controller, which provides a very elegant way to decorate the context with custom
functions/properties.

/**
`bind-attr` allows you to create a binding between DOM element attributes and
Ember objects. For example:
```handlebars
<img {{bind-attr src="imageUrl" alt="imageTitle"}}>
```
The above handlebars template will fill the `<img>`'s `src` attribute will
the value of the property referenced with `"imageUrl"` and its `alt`
attribute with the value of the property referenced with `"imageTitle"`.
If the rendering context of this template is the following object:
```javascript
{
imageUrl: 'http://lolcats.info/haz-a-funny',
imageTitle: 'A humorous image of a cat'
}
```
The resulting HTML output will be:
```html
<img src="http://lolcats.info/haz-a-funny" alt="A humorous image of a cat">
```
`bind-attr` cannot redeclare existing DOM element attributes. The use of `src`
in the following `bind-attr` example will be ignored and the hard coded value
of `src="/failwhale.gif"` will take precedence:
```handlebars
<img src="/failwhale.gif" {{bind-attr src="imageUrl" alt="imageTitle"}}>
```
### `bind-attr` and the `class` attribute
`bind-attr` supports a special syntax for handling a number of cases unique
to the `class` DOM element attribute. The `class` attribute combines
multiple discrete values into a single attribute as a space-delimited
list of strings. Each string can be:
* a string return value of an object's property.
* a boolean return value of an object's property
* a hard-coded value
A string return value works identically to other uses of `bind-attr`. The
return value of the property will become the value of the attribute. For
example, the following view and template:
```javascript
AView = View.extend({
someProperty: function() {
return "aValue";
}.property()
})
```
```handlebars
<img {{bind-attr class="view.someProperty}}>
```
Result in the following rendered output:
```html
<img class="aValue">
```
A boolean return value will insert a specified class name if the property
returns `true` and remove the class name if the property returns `false`.
A class name is provided via the syntax
`somePropertyName:class-name-if-true`.
```javascript
AView = View.extend({
someBool: true
})
```
```handlebars
<img {{bind-attr class="view.someBool:class-name-if-true"}}>
```
Result in the following rendered output:
```html
<img class="class-name-if-true">
```
An additional section of the binding can be provided if you want to
replace the existing class instead of removing it when the boolean
value changes:
```handlebars
<img {{bind-attr class="view.someBool:class-name-if-true:class-name-if-false"}}>
```
A hard-coded value can be used by prepending `:` to the desired
class name: `:class-name-to-always-apply`.
```handlebars
<img {{bind-attr class=":class-name-to-always-apply"}}>
```
Results in the following rendered output:
```html
<img class="class-name-to-always-apply">
```
All three strategies - string return value, boolean return value, and
hard-coded value – can be combined in a single declaration:
```handlebars
<img {{bind-attr class=":class-name-to-always-apply view.someBool:class-name-if-true view.someProperty"}}>
```

/**
`{{collection}}` is a `Ember.Handlebars` helper for adding instances of
`Ember.CollectionView` to a template. See [Ember.CollectionView](/api/classes/Ember.CollectionView.html)
for additional information on how a `CollectionView` functions.
`{{collection}}`'s primary use is as a block helper with a `contentBinding`
option pointing towards an `Ember.Array`-compatible object. An `Ember.View`
instance will be created for each item in its `content` property. Each view
will have its own `content` property set to the appropriate item in the
collection.
The provided block will be applied as the template for each item's view.
Given an empty `<body>` the following template:
```handlebars
{{#collection contentBinding="App.items"}}
Hi {{view.content.name}}
{{/collection}}
```
And the following application code
```javascript
App = Ember.Application.create()
App.items = [
Ember.Object.create({name: 'Dave'}),
Ember.Object.create({name: 'Mary'}),
Ember.Object.create({name: 'Sara'})
]
```
Will result in the HTML structure below
```html
<div class="ember-view">
<div class="ember-view">Hi Dave</div>
<div class="ember-view">Hi Mary</div>
<div class="ember-view">Hi Sara</div>
</div>
```
### Blockless use in a collection
If you provide an `itemViewClass` option that has its own `template` you can
omit the block.
The following template:
```handlebars
{{collection contentBinding="App.items" itemViewClass="App.AnItemView"}}
```
And application code
```javascript
App = Ember.Application.create();
App.items = [
Ember.Object.create({name: 'Dave'}),
Ember.Object.create({name: 'Mary'}),
Ember.Object.create({name: 'Sara'})
];
App.AnItemView = Ember.View.extend({
template: Ember.Handlebars.compile("Greetings {{view.content.name}}")
});
```
Will result in the HTML structure below
```html
<div class="ember-view">
<div class="ember-view">Greetings Dave</div>
<div class="ember-view">Greetings Mary</div>
<div class="ember-view">Greetings Sara</div>
</div>
```
### Specifying a CollectionView subclass
By default the `{{collection}}` helper will create an instance of
`Ember.CollectionView`. You can supply a `Ember.CollectionView` subclass to
the helper by passing it as the first argument:
```handlebars
{{#collection App.MyCustomCollectionClass contentBinding="App.items"}}
Hi {{view.content.name}}
{{/collection}}
```
### Forwarded `item.*`-named Options
As with the `{{view}}`, helper options passed to the `{{collection}}` will be
set on the resulting `Ember.CollectionView` as properties. Additionally,
options prefixed with `item` will be applied to the views rendered for each
item (note the camelcasing):
```handlebars
{{#collection contentBinding="App.items"
itemTagName="p"
itemClassNames="greeting"}}
Howdy {{view.content.name}}
{{/collection}}
```
Will result in the following HTML structure:
```html
<div class="ember-view">
<p class="ember-view greeting">Howdy Dave</p>
<p class="ember-view greeting">Howdy Mary</p>
<p class="ember-view greeting">Howdy Sara</p>

/**
The `{{#each}}` helper loops over elements in a collection, rendering its
block once for each item. It is an extension of the base Handlebars `{{#each}}`
helper:
```javascript
Developers = [{name: 'Yehuda'},{name: 'Tom'}, {name: 'Paul'}];
```
```handlebars
{{#each Developers}}
{{name}}
{{/each}}
```
`{{each}}` supports an alternative syntax with element naming:
```handlebars
{{#each person in Developers}}
{{person.name}}
{{/each}}
```
When looping over objects that do not have properties, `{{this}}` can be used
to render the object:
```javascript
DeveloperNames = ['Yehuda', 'Tom', 'Paul']
```
```handlebars
{{#each DeveloperNames}}
{{this}}
{{/each}}
```
### {{else}} condition
`{{#each}}` can have a matching `{{else}}`. The contents of this block will render
if the collection is empty.
```
{{#each person in Developers}}
{{person.name}}
{{else}}
<p>Sorry, nobody is available for this task.</p>
{{/each}}
```
### Specifying a View class for items
If you provide an `itemViewClass` option that references a view class
with its own `template` you can omit the block.
The following template:
```handlebars
{{#view App.MyView }}
{{each view.items itemViewClass="App.AnItemView"}}
{{/view}}
```
And application code
```javascript
App = Ember.Application.create({
MyView: Ember.View.extend({
items: [
Ember.Object.create({name: 'Dave'}),
Ember.Object.create({name: 'Mary'}),
Ember.Object.create({name: 'Sara'})
]
})
});
App.AnItemView = Ember.View.extend({
template: Ember.Handlebars.compile("Greetings {{name}}")
});
```
Will result in the HTML structure below
```html
<div class="ember-view">
<div class="ember-view">Greetings Dave</div>
<div class="ember-view">Greetings Mary</div>
<div class="ember-view">Greetings Sara</div>
</div>
```
If an `itemViewClass` is defined on the helper, and therefore the helper is not
being used as a block, an `emptyViewClass` can also be provided optionally.
The `emptyViewClass` will match the behavior of the `{{else}}` condition
described above. That is, the `emptyViewClass` will render if the collection
is empty.
### Representing each item with a Controller.
By default the controller lookup within an `{{#each}}` block will be
the controller of the template where the `{{#each}}` was used. If each
item needs to be presented by a custom controller you can provide a
`itemController` option which references a controller by lookup name.
Each item in the loop will be wrapped in an instance of this controller
and the item itself will be set to the `model` property of that controller.
This is useful in cases where properties of model objects need transformation
or synthesis for display:
```javascript
App.DeveloperController = Ember.ObjectController.extend({
isAvailableForHire: function() {
return !this.get('model.isEmployed') && this.get('model.isSeekingWork');
}.property('isEmployed', 'isSeekingWork')
})
```
```handlebars
{{#each person in developers itemController="developer"}}
{{person.name}} {{#if person.isAvailableForHire}}Hire me!{{/if}}
{{/each}}
```
Each itemController will receive a reference to the current controller as
a `parentController` property.
### (Experimental) Grouped Each
When used in conjunction with the experimental [group helper](https://github.com/emberjs/group-helper),
you can inform Handlebars to re-render an entire group of items instead of
re-rendering them one at a time (in the event that they are changed en masse
or an item is added/removed).
```handlebars
{{#group}}
{{#each people}}
{{firstName}} {{lastName}}
{{/each}}
{{/group}}
```
This can be faster than the normal way that Handlebars re-renders items
in some cases.
If for some reason you have a group with more than one `#each`, you can make
one of the collections be updated in normal (non-grouped) fashion by setting
the option `groupedRows=true` (counter-intuitive, I know).
For example,
```handlebars
{{dealershipName}}
{{#group}}
{{#each dealers}}
{{firstName}} {{lastName}}
{{/each}}
{{#each car in cars groupedRows=true}}
{{car.make}} {{car.model}} {{car.color}}
{{/each}}
{{/group}}
```
Any change to `dealershipName` or the `dealers` collection will cause the
entire group to be re-rendered. However, changes to the `cars` collection
will be re-rendered individually (as normal).
Note that `group` behavior is also disabled by specifying an `itemViewClass`.

The `partial` helper renders another template without
changing the template context:
```handlebars
{{foo}}
{{partial "nav"}}
```
The above example template will render a template named
"_nav", which has the same context as the parent template
it's rendered into, so if the "_nav" template also referenced
`{{foo}}`, it would print the same thing as the `{{foo}}`
in the above example.
If a "_nav" template isn't found, the `partial` helper will
fall back to a template named "nav".
## Bound template names
The parameter supplied to `partial` can also be a path
to a property containing a template name, e.g.:
```handlebars
{{partial someTemplateName}}
```
The above example will look up the value of `someTemplateName`
on the template context (e.g. a controller) and use that
value as the name of the template to render. If the resolved
value is falsy, nothing will be rendered. If `someTemplateName`
changes, the partial will be re-rendered using the new template
name.
## Setting the partial's context with `with`
The `partial` helper can be used in conjunction with the `with`
helper to set a context that will be used by the partial:
```handlebars
{{#with currentUser}}
{{partial "user_info"}}
{{/with}}
```

/**
`{{view}}` inserts a new instance of an `Ember.View` into a template passing its
options to the `Ember.View`'s `create` method and using the supplied block as
the view's own template.
An empty `<body>` and the following template:
```handlebars
A span:
{{#view tagName="span"}}
hello.
{{/view}}
```
Will result in HTML structure:
```html
<body>
<!-- Note: the handlebars template script
also results in a rendered Ember.View
which is the outer <div> here -->
<div class="ember-view">
A span:
<span id="ember1" class="ember-view">
Hello.
</span>
</div>
</body>
```
### `parentView` setting
The `parentView` property of the new `Ember.View` instance created through
`{{view}}` will be set to the `Ember.View` instance of the template where
`{{view}}` was called.
```javascript
aView = Ember.View.create({
template: Ember.Handlebars.compile("{{#view}} my parent: {{parentView.elementId}} {{/view}}")
});
aView.appendTo('body');
```
Will result in HTML structure:
```html
<div id="ember1" class="ember-view">
<div id="ember2" class="ember-view">
my parent: ember1
</div>
</div>
```
### Setting CSS id and class attributes
The HTML `id` attribute can be set on the `{{view}}`'s resulting element with
the `id` option. This option will _not_ be passed to `Ember.View.create`.
```handlebars
{{#view tagName="span" id="a-custom-id"}}
hello.
{{/view}}
```
Results in the following HTML structure:
```html
<div class="ember-view">
<span id="a-custom-id" class="ember-view">
hello.
</span>
</div>
```
The HTML `class` attribute can be set on the `{{view}}`'s resulting element
with the `class` or `classNameBindings` options. The `class` option will
directly set the CSS `class` attribute and will not be passed to
`Ember.View.create`. `classNameBindings` will be passed to `create` and use
`Ember.View`'s class name binding functionality:
```handlebars
{{#view tagName="span" class="a-custom-class"}}
hello.
{{/view}}
```
Results in the following HTML structure:
```html
<div class="ember-view">
<span id="ember2" class="ember-view a-custom-class">
hello.
</span>
</div>
```
### Supplying a different view class
`{{view}}` can take an optional first argument before its supplied options to
specify a path to a custom view class.
```handlebars
{{#view "MyApp.CustomView"}}
hello.
{{/view}}
```
The first argument can also be a relative path accessible from the current
context.
```javascript
MyApp = Ember.Application.create({});
MyApp.OuterView = Ember.View.extend({
innerViewClass: Ember.View.extend({
classNames: ['a-custom-view-class-as-property']
}),
template: Ember.Handlebars.compile('{{#view "view.innerViewClass"}} hi {{/view}}')
});
MyApp.OuterView.create().appendTo('body');
```
Will result in the following HTML:
```html
<div id="ember1" class="ember-view">
<div id="ember2" class="ember-view a-custom-view-class-as-property">
hi
</div>
</div>
```
### Blockless use
If you supply a custom `Ember.View` subclass that specifies its own template
or provide a `templateName` option to `{{view}}` it can be used without
supplying a block. Attempts to use both a `templateName` option and supply a
block will throw an error.
```handlebars
{{view "MyApp.ViewWithATemplateDefined"}}
```
### `viewName` property
You can supply a `viewName` option to `{{view}}`. The `Ember.View` instance
will be referenced as a property of its parent view by this name.
```javascript
aView = Ember.View.create({
template: Ember.Handlebars.compile('{{#view viewName="aChildByName"}} hi {{/view}}')
});
aView.appendTo('body');
aView.get('aChildByName') // the instance of Ember.View created by {{view}} helper
```

// If no path is provided, treat path param as options
// and get an instance of the registered `view:default`
if (path && path.data && path.data.isRenderData) {
options = path;
Ember.assert('{{view}} helper requires parent view to have a container but none was found. This usually happens when you are manually-managing views.', !!options.data.view.container);
path = options.data.view.container.lookupFactory('view:default');

`{{yield}}` denotes an area of a template that will be rendered inside
of another template. It has two main uses:
### Use with `layout`
When used in a Handlebars template that is assigned to an `Ember.View`
instance's `layout` property Ember will render the layout template first,
inserting the view's own rendered output at the `{{yield}}` location.
An empty `<body>` and the following application code:
```javascript
AView = Ember.View.extend({
classNames: ['a-view-with-layout'],
layout: Ember.Handlebars.compile('<div class="wrapper">{{yield}}</div>'),
template: Ember.Handlebars.compile('<span>I am wrapped</span>')
});
aView = AView.create();
aView.appendTo('body');
```
Will result in the following HTML output:
```html
<body>
<div class='ember-view a-view-with-layout'>
<div class="wrapper">
<span>I am wrapped</span>
</div>
</div>
</body>
```
The `yield` helper cannot be used outside of a template assigned to an
`Ember.View`'s `layout` property and will throw an error if attempted.
```javascript
BView = Ember.View.extend({
classNames: ['a-view-with-layout'],
template: Ember.Handlebars.compile('{{yield}}')
});
bView = BView.create();
bView.appendTo('body');
// throws
// Uncaught Error: assertion failed:
// You called yield in a template that was not a layout
```
### Use with Ember.Component
When designing components `{{yield}}` is used to denote where, inside the component's
template, an optional block passed to the component should render:
```handlebars
<!-- application.hbs -->
{{#labeled-textfield value=someProperty}}
First name:
{{/labeled-textfield}}
```
```handlebars
<!-- components/labeled-textfield.hbs -->
<label>
{{yield}} {{input value=value}}
</label>
```
Result:
```html
<label>
First name: <input type="text" />
</label>
```

/**
An `Ember.Binding` connects the properties of two objects so that whenever
the value of one property changes, the other property will be changed also.
## Automatic Creation of Bindings with `/^*Binding/`-named Properties
You do not usually create Binding objects directly but instead describe
bindings in your class or object definition using automatic binding
detection.
Properties ending in a `Binding` suffix will be converted to `Ember.Binding`
instances. The value of this property should be a string representing a path
to another object or a custom binding instanced created using Binding helpers
(see "One Way Bindings"):
```
valueBinding: "MyApp.someController.title"
```
This will create a binding from `MyApp.someController.title` to the `value`
property of your object instance automatically. Now the two values will be
kept in sync.
## One Way Bindings
One especially useful binding customization you can use is the `oneWay()`
helper. This helper tells Ember that you are only interested in
receiving changes on the object you are binding from. For example, if you
are binding to a preference and you want to be notified if the preference
has changed, but your object will not be changing the preference itself, you
could do:
```
bigTitlesBinding: Ember.Binding.oneWay("MyApp.preferencesController.bigTitles")
```
This way if the value of `MyApp.preferencesController.bigTitles` changes the
`bigTitles` property of your object will change also. However, if you
change the value of your `bigTitles` property, it will not update the
`preferencesController`.
One way bindings are almost twice as fast to setup and twice as fast to
execute because the binding only has to worry about changes to one side.
You should consider using one way bindings anytime you have an object that
may be created frequently and you do not intend to change a property; only
to monitor it for changes (such as in the example above).
## Adding Bindings Manually
All of the examples above show you how to configure a custom binding, but the
result of these customizations will be a binding template, not a fully active
Binding instance. The binding will actually become active only when you
instantiate the object the binding belongs to. It is useful however, to
understand what actually happens when the binding is activated.
For a binding to function it must have at least a `from` property and a `to`
property. The `from` property path points to the object/key that you want to
bind from while the `to` path points to the object/key you want to bind to.
When you define a custom binding, you are usually describing the property
you want to bind from (such as `MyApp.someController.value` in the examples
above). When your object is created, it will automatically assign the value
you want to bind `to` based on the name of your binding key. In the
examples above, during init, Ember objects will effectively call
something like this on your binding:
```javascript
binding = Ember.Binding.from(this.valueBinding).to("value");
```
This creates a new binding instance based on the template you provide, and
sets the to path to the `value` property of the new object. Now that the
binding is fully configured with a `from` and a `to`, it simply needs to be
connected to become active. This is done through the `connect()` method:
```javascript
binding.connect(this);
```
Note that when you connect a binding you pass the object you want it to be
connected to. This object will be used as the root for both the from and
to side of the binding when inspecting relative paths. This allows the
binding to be automatically inherited by subclassed objects as well.
Now that the binding is connected, it will observe both the from and to side
and relay changes.
If you ever needed to do so (you almost never will, but it is useful to
understand this anyway), you could manually create an active binding by
using the `Ember.bind()` helper method. (This is the same method used by
to setup your bindings on objects):
```javascript
Ember.bind(MyApp.anotherObject, "value", "MyApp.someController.value");
```
Both of these code fragments have the same effect as doing the most friendly
form of binding creation like so:
```javascript
MyApp.anotherObject = Ember.Object.create({
valueBinding: "MyApp.someController.value",
// OTHER CODE FOR THIS OBJECT...
});
```
Ember's built in binding creation method makes it easy to automatically
create bindings for you. You should always use the highest-level APIs
available, even if you understand how it works underneath.

// COMPUTED PROPERTY
//
/**
A computed property transforms an objects function into a property.
By default the function backing the computed property will only be called
once and the result will be cached. You can specify various properties
that your computed property is dependent on. This will force the cached
result to be recomputed if the dependencies are modified.
In the following example we declare a computed property (by calling
`.property()` on the fullName function) and setup the properties
dependencies (depending on firstName and lastName). The fullName function
will be called once (regardless of how many times it is accessed) as long
as it's dependencies have not been changed. Once firstName or lastName are updated
any future calls (or anything bound) to fullName will incorporate the new
values.
```javascript
Person = Ember.Object.extend({
// these will be supplied by `create`
firstName: null,
lastName: null,
fullName: function() {
var firstName = this.get('firstName');
var lastName = this.get('lastName');
return firstName + ' ' + lastName;
}.property('firstName', 'lastName')
});
var tom = Person.create({
firstName: 'Tom',
lastName: 'Dale'
});
tom.get('fullName') // 'Tom Dale'
```
You can also define what Ember should do when setting a computed property.
If you try to set a computed property, it will be invoked with the key and
value you want to set it to. You can also accept the previous value as the
third parameter.
```javascript
Person = Ember.Object.extend({
// these will be supplied by `create`
firstName: null,
lastName: null,
fullName: function(key, value, oldValue) {
// getter
if (arguments.length === 1) {
var firstName = this.get('firstName');
var lastName = this.get('lastName');
return firstName + ' ' + lastName;
// setter
} else {
var name = value.split(" ");
this.set('firstName', name[0]);
this.set('lastName', name[1]);
return value;
}
}.property('firstName', 'lastName')
});
var person = Person.create();
person.set('fullName', 'Peter Wagenet');
person.get('firstName') // 'Peter'

The purpose of the Ember Instrumentation module is
to provide efficient, general-purpose instrumentation
for Ember.
Subscribe to a listener by using `Ember.subscribe`:
```javascript
Ember.subscribe("render", {
before: function(name, timestamp, payload) {
},
after: function(name, timestamp, payload) {
}
});
```
If you return a value from the `before` callback, that same
value will be passed as a fourth parameter to the `after`
callback.
Instrument a block of code by using `Ember.instrument`:
```javascript
Ember.instrument("render.handlebars", payload, function() {
// rendering logic
}, binding);
```
Event names passed to `Ember.instrument` are namespaced
by periods, from more general to more specific. Subscribers
can listen for events by whatever level of granularity they
are interested in.
In the above example, the event is `render.handlebars`,
and the subscriber listened for all events beginning with
`render`. It would receive callbacks for events named
`render`, `render.handlebars`, `render.container`, or
even `render.handlebars.layout`.

JavaScript (before ES6) does not have a Map implementation. Objects,
which are often used as dictionaries, may only have Strings as keys.
Because Ember has a way to get a unique identifier for every object
via `Ember.guidFor`, we can implement a performant Map with arbitrary
keys. Because it is commonly used in low-level bookkeeping, Map is
implemented as a pure JavaScript object for performance.
This implementation follows the current iteration of the ES6 proposal for
maps (http://wiki.ecmascript.org/doku.php?id=harmony:simple_maps_and_sets),
with two exceptions. First, because we need our implementation to be pleasant
on older browsers, we do not use the `delete` name (using `remove` instead).
Second, as we do not have the luxury of in-VM iteration, we implement a
forEach method for iteration.
Map is mocked out to look like an Ember object, so you can do
`Ember.Map.create()` for symmetry with other Ember classes.

The `Ember.Mixin` class allows you to create mixins, whose properties can be
added to other classes. For instance,
```javascript
App.Editable = Ember.Mixin.create({
edit: function() {
console.log('starting to edit');
this.set('isEditing', true);
},
isEditing: false
});
// Mix mixins into classes by passing them as the first arguments to
// .extend.
App.CommentView = Ember.View.extend(App.Editable, {
template: Ember.Handlebars.compile('{{#if view.isEditing}}...{{else}}...{{/if}}')
});
commentView = App.CommentView.create();
commentView.edit(); // outputs 'starting to edit'
```
Note that Mixins are created with `Ember.Mixin.create`, not
`Ember.Mixin.extend`.
Note that mixins extend a constructor's prototype so arrays and object literals
defined as properties will be shared amongst objects that implement the mixin.
If you want to define a property in a mixin that is not shared, you can define
it either as a computed property or have it be created on initialization of the object.
```javascript
//filters array will be shared amongst any object implementing mixin
App.Filterable = Ember.Mixin.create({
filters: Ember.A()
});
//filters will be a separate array for every object implementing the mixin
App.Filterable = Ember.Mixin.create({
filters: Ember.computed(function(){return Ember.A();})
});
//filters will be created as a separate array during the object's initialization
App.Filterable = Ember.Mixin.create({
init: function() {
this._super();
this.set("filters", Ember.A());
}
});

Normally this method takes only three parameters. However if you pass an
instance of `Ember.Descriptor` as the third param then you can pass an
optional value as the fourth parameter. This is often more efficient than
creating new descriptor hashes for each property.
## Examples
```javascript
// ES5 compatible mode
Ember.defineProperty(contact, 'firstName', {
writable: true,
configurable: false,
enumerable: true,
value: 'Charles'
});
// define a simple property
Ember.defineProperty(contact, 'lastName', undefined, 'Jolley');
// define a computed property
Ember.defineProperty(contact, 'fullName', Ember.computed(function() {
return this.firstName+' '+this.lastName;
}).property('firstName', 'lastName'));
```
@private
@method defineProperty
@for Ember
@param {Object} obj the object to define this property on. This may be a prototype.
@param {String} keyName the name of the property
@param {Ember.Descriptor} [desc] an instance of `Ember.Descriptor` (typically a
computed property) or an ES5 descriptor.
You must provide this or `data` but not both.
@param {*} [data] something other than a descriptor, that will
become the explicit value of this property.

Provides a useful utility for when integrating with non-Ember libraries

Ember utilizes a run-loop to batch and coalesce changes. This works by
marking the start and end of Ember-related Javascript execution.
When using events such as a View's click handler, Ember wraps the event
handler in a run-loop, but when integrating with non-Ember libraries this
can be tedious.
For example, the following is rather verbose but is the correct way to combine
third-party events and Ember code.
```javascript
var that = this;
jQuery(window).on('resize', function(){
run(function(){
that.handleResize();
});
});
```
To reduce the boilerplate, the following can be used to construct a

```javascript
jQuery(window).on('resize', run.bind(this, this.handleResize));

Calling this method with the same queue/target/method combination will have
no effect (past the initial call).

function scheduleIt() {
run.scheduleOnce('actions', myContext, function() { console.log("Closure"); });
}
scheduleIt();
scheduleIt();

Schedules an item to run from within a separate run loop, after

`run.later` with a wait time of 1ms.
```javascript
run.next(myContext, function() {
// code to be executed in the next run loop,
// which will be scheduled after the current one
});
```
Multiple operations scheduled with `run.next` will coalesce
into the same later run loop, along with any other operations
scheduled by `run.later` that expire right around the same
time that `run.next` operations will fire.
Note that there are often alternatives to using `run.next`.
For instance, if you'd like to schedule an operation to happen
after all DOM element operations have completed within the current
run loop, you can make use of the `afterRender` run loop queue (added
by the `ember-views` package, along with the preceding `render` queue
where all the DOM element operations happen). Example:
```javascript
App.MyCollectionView = Ember.CollectionView.extend({
didInsertElement: function() {
run.scheduleOnce('afterRender', this, 'processChildElements');
},
processChildElements: function() {
// ... do something with collectionView's child view
// elements after they've finished rendering, which
// can't be done within the CollectionView's
// `didInsertElement` hook because that gets run
// before the child elements have been added to the DOM.
}
});
```
One benefit of the above approach compared to using `run.next` is
that you will be able to perform DOM/CSS operations before unprocessed
elements are rendered to the screen, which may prevent flickering or
other artifacts caused by delaying processing until after rendering.
The other major benefit to the above approach is that `run.next`
introduces an element of non-determinism, which can make things much
harder to test, due to its reliance on `setTimeout`; it's much harder
to guarantee the order of scheduled operations when they are scheduled
outside of the current run loop, i.e. with `run.next`.

This method should be used when an event may be called multiple times
but the action should only be called once when the event is done firing.
A common example is for scroll events where you only want updates to
happen once scrolling has ceased.

@deprecated
@private
In order to store defaults for a class, a prototype may need to create
a default meta object, which will be inherited by any objects instantiated
from the class's constructor.
However, the properties of that meta object are only shallow-cloned,
so if a property is a hash (like the event system's `listeners` hash),
it will by default be shared across all instances of that class.
This method allows extensions to deeply clone a series of nested hashes or
other complex objects. For instance, the event system might pass
`['listeners', 'foo:change', 'ember157']` to `prepareMetaPath`, which will
walk down the keys provided.
For each key, if the key does not exist, it is created. If it already
exists and it was inherited from its constructor, the constructor's
key is cloned.
You can also pass false for `writable`, which will simply return
undefined if `prepareMetaPath` discovers any part of the path that
shared or undefined.

/**
The `{{action}}` helper registers an HTML element within a template for DOM
event handling and forwards that interaction to the templates's controller
or supplied `target` option (see 'Specifying a Target').
If the controller does not implement the event, the event is sent
to the current route, and it bubbles up the route hierarchy from there.
User interaction with that element will invoke the supplied action name on
the appropriate target. Specifying a non-quoted action name will result in
a bound property lookup at the time the event will be triggered.
Given the following application Handlebars template on the page
```handlebars
<div {{action 'anActionName'}}>
click me
</div>
```
And application code
```javascript
App.ApplicationController = Ember.Controller.extend({
actions: {
anActionName: function() {
}
}
});
```
Will result in the following rendered HTML
```html
<div class="ember-view">
<div data-ember-action="1">
click me
</div>
</div>
```
Clicking "click me" will trigger the `anActionName` action of the
`App.ApplicationController`. In this case, no additional parameters will be passed.
If you provide additional parameters to the helper:
```handlebars
<button {{action 'edit' post}}>Edit</button>
```
Those parameters will be passed along as arguments to the JavaScript
function implementing the action.
### Event Propagation
Events triggered through the action helper will automatically have
`.preventDefault()` called on them. You do not need to do so in your event
handlers. If you need to allow event propagation (to handle file inputs for
example) you can supply the `preventDefault=false` option to the `{{action}}` helper:
```handlebars
<div {{action "sayHello" preventDefault=false}}>
<input type="file" />
<input type="checkbox" />
</div>
```
To disable bubbling, pass `bubbles=false` to the helper:
```handlebars
<button {{action 'edit' post bubbles=false}}>Edit</button>
```
If you need the default handler to trigger you should either register your
own event handler, or use event methods on your view class. See [Ember.View](/api/classes/Ember.View.html)
'Responding to Browser Events' for more information.
### Specifying DOM event type
By default the `{{action}}` helper registers for DOM `click` events. You can
supply an `on` option to the helper to specify a different DOM event name:
```handlebars
<div {{action "anActionName" on="doubleClick"}}>
click me
</div>
```
See `Ember.View` 'Responding to Browser Events' for a list of
acceptable DOM event names.
NOTE: Because `{{action}}` depends on Ember's event dispatch system it will
only function if an `Ember.EventDispatcher` instance is available. An
`Ember.EventDispatcher` instance will be created when a new `Ember.Application`
is created. Having an instance of `Ember.Application` will satisfy this
requirement.
### Specifying whitelisted modifier keys
By default the `{{action}}` helper will ignore click event with pressed modifier
keys. You can supply an `allowedKeys` option to specify which keys should not be ignored.
```handlebars
<div {{action "anActionName" allowedKeys="alt"}}>
click me
</div>
```
This way the `{{action}}` will fire when clicking with the alt key pressed down.
Alternatively, supply "any" to the `allowedKeys` option to accept any combination of modifier keys.
```handlebars
<div {{action "anActionName" allowedKeys="any"}}>
click me with any key pressed
</div>
```
### Specifying a Target
There are several possible target objects for `{{action}}` helpers:
In a typical Ember application, where views are managed through use of the
`{{outlet}}` helper, actions will bubble to the current controller, then
to the current route, and then up the route hierarchy.
Alternatively, a `target` option can be provided to the helper to change
which object will receive the method call. This option must be a path
to an object, accessible in the current context:
```handlebars
{{! the application template }}
<div {{action "anActionName" target=view}}>
click me
</div>
```
```javascript
App.ApplicationView = Ember.View.extend({
actions: {
anActionName: function(){}
}
});
```
### Additional Parameters
You may specify additional parameters to the `{{action}}` helper. These
parameters are passed along as the arguments to the JavaScript function
implementing the action.
```handlebars
{{#each person in people}}
<div {{action "edit" person}}>
click me
</div>
{{/each}}
```
Clicking "click me" will trigger the `edit` method on the current controller
with the value of `person` as a parameter.

The `{{link-to}}` helper renders a link to the supplied
`routeName` passing an optionally supplied model to the
route as its `model` context of the route. The block
for `{{link-to}}` becomes the innerHTML of the rendered
element:
```handlebars
{{#link-to 'photoGallery'}}
Great Hamster Photos
{{/link-to}}
```
```html
<a href="/hamster-photos">
Great Hamster Photos
</a>
```
### Supplying a tagName
By default `{{link-to}}` renders an `<a>` element. This can
be overridden for a single use of `{{link-to}}` by supplying
a `tagName` option:
```handlebars
{{#link-to 'photoGallery' tagName="li"}}
Great Hamster Photos
{{/link-to}}
```
```html
<li>
Great Hamster Photos
</li>
```
To override this option for your entire application, see
"Overriding Application-wide Defaults".
### Disabling the `link-to` helper
By default `{{link-to}}` is enabled.
any passed value to `disabled` helper property will disable the `link-to` helper.
static use: the `disabled` option:
```handlebars
{{#link-to 'photoGallery' disabled=true}}
Great Hamster Photos
{{/link-to}}
```
dynamic use: the `disabledWhen` option:
```handlebars
{{#link-to 'photoGallery' disabledWhen=controller.someProperty}}
Great Hamster Photos
{{/link-to}}
```
any passed value to `disabled` will disable it except `undefined`.
to ensure that only `true` disable the `link-to` helper you can
override the global behaviour of `Ember.LinkView`.
```javascript
Ember.LinkView.reopen({
disabled: Ember.computed(function(key, value) {
if (value !== undefined) {
this.set('_isDisabled', value === true);
}
return value === true ? get(this, 'disabledClass') : false;
})
});
```
see "Overriding Application-wide Defaults" for more.
### Handling `href`
`{{link-to}}` will use your application's Router to
fill the element's `href` property with a url that
matches the path to the supplied `routeName` for your
routers's configured `Location` scheme, which defaults
to Ember.HashLocation.
### Handling current route
`{{link-to}}` will apply a CSS class name of 'active'
when the application's current route matches
the supplied routeName. For example, if the application's
current route is 'photoGallery.recent' the following
use of `{{link-to}}`:
```handlebars
{{#link-to 'photoGallery.recent'}}
Great Hamster Photos from the last week
{{/link-to}}
```
will result in
```html
<a href="/hamster-photos/this-week" class="active">
Great Hamster Photos
</a>
```
The CSS class name used for active classes can be customized
for a single use of `{{link-to}}` by passing an `activeClass`
option:
```handlebars
{{#link-to 'photoGallery.recent' activeClass="current-url"}}
Great Hamster Photos from the last week
{{/link-to}}
```
```html
<a href="/hamster-photos/this-week" class="current-url">
Great Hamster Photos
</a>
```
To override this option for your entire application, see
"Overriding Application-wide Defaults".
### Supplying a model
An optional model argument can be used for routes whose
paths contain dynamic segments. This argument will become
the model context of the linked route:
```javascript
App.Router.map(function() {
this.resource("photoGallery", {path: "hamster-photos/:photo_id"});
});
```
```handlebars
{{#link-to 'photoGallery' aPhoto}}
{{aPhoto.title}}
{{/link-to}}
```
```html
<a href="/hamster-photos/42">
Tomster
</a>
```
### Supplying multiple models
For deep-linking to route paths that contain multiple
dynamic segments, multiple model arguments can be used.
As the router transitions through the route path, each
supplied model argument will become the context for the
route with the dynamic segments:
```javascript
App.Router.map(function() {
this.resource("photoGallery", {path: "hamster-photos/:photo_id"}, function() {
this.route("comment", {path: "comments/:comment_id"});
});
});
```
This argument will become the model context of the linked route:
```handlebars
{{#link-to 'photoGallery.comment' aPhoto comment}}
{{comment.body}}
{{/link-to}}
```
```html
<a href="/hamster-photos/42/comment/718">
A+++ would snuggle again.
</a>
```
### Supplying an explicit dynamic segment value
If you don't have a model object available to pass to `{{link-to}}`,
an optional string or integer argument can be passed for routes whose
paths contain dynamic segments. This argument will become the value
of the dynamic segment:
```javascript
App.Router.map(function() {
this.resource("photoGallery", {path: "hamster-photos/:photo_id"});
});
```
```handlebars
{{#link-to 'photoGallery' aPhotoId}}
{{aPhoto.title}}
{{/link-to}}
```
```html
<a href="/hamster-photos/42">
Tomster
</a>
```
When transitioning into the linked route, the `model` hook will
be triggered with parameters including this passed identifier.
### Allowing Default Action
By default the `{{link-to}}` helper prevents the default browser action
by calling `preventDefault()` as this sort of action bubbling is normally
handled internally and we do not want to take the browser to a new URL (for
example).
If you need to override this behavior specify `preventDefault=false` in
your template:
```handlebars
{{#link-to 'photoGallery' aPhotoId preventDefault=false}}
{{aPhotoId.title}}
{{/link-to}}
```
### Overriding attributes
You can override any given property of the Ember.LinkView
that is generated by the `{{link-to}}` helper by passing
key/value pairs, like so:
```handlebars
{{#link-to aPhoto tagName='li' title='Following this link will change your life' classNames='pic sweet'}}
Uh-mazing!
{{/link-to}}
```
See [Ember.LinkView](/api/classes/Ember.LinkView.html) for a
complete list of overrideable properties. Be sure to also
check out inherited properties of `LinkView`.
### Overriding Application-wide Defaults
``{{link-to}}`` creates an instance of Ember.LinkView
for rendering. To override options for your entire
application, reopen Ember.LinkView and supply the
desired values:
``` javascript
Ember.LinkView.reopen({
activeClass: "is-active",
tagName: 'li'
})
```
It is also possible to override the default event in
this manner:
``` javascript
Ember.LinkView.reopen({
eventName: 'customEventName'
});
```

The `outlet` helper is a placeholder that the router will fill in with
the appropriate template based on the current state of the application.
``` handlebars
{{outlet}}
```
By default, a template based on Ember's naming conventions will be rendered
into the `outlet` (e.g. `App.PostsRoute` will render the `posts` template).
You can render a different template by using the `render()` method in the
route's `renderTemplate` hook. The following will render the `favoritePost`
template into the `outlet`.
``` javascript
App.PostsRoute = Ember.Route.extend({
renderTemplate: function() {
this.render('favoritePost');
}
});
```
You can create custom named outlets for more control.
``` handlebars
{{outlet 'favoritePost'}}
{{outlet 'posts'}}
```
Then you can define what template is rendered into each outlet in your
route.
``` javascript
App.PostsRoute = Ember.Route.extend({
renderTemplate: function() {
this.render('favoritePost', { outlet: 'favoritePost' });
this.render('posts', { outlet: 'posts' });
}
});
```
You can specify the view that the outlet uses to contain and manage the
templates rendered into it.
``` handlebars
{{outlet view='sectionContainer'}}

``` javascript
App.SectionContainer = Ember.ContainerView.extend({
tagName: 'section',
classNames: ['special']

Calling ``{{render}}`` from within a template will insert another
template that matches the provided name. The inserted template will
access its properties on its own controller (rather than the controller
of the parent template).
If a view class with the same name exists, the view class also will be used.
Note: A given controller may only be used *once* in your app in this manner.
A singleton instance of the controller will be created for you.
Example:
```javascript
App.NavigationController = Ember.Controller.extend({
who: "world"
});
```
```handlebars
<!-- navigation.hbs -->
Hello, {{who}}.
```
```handelbars
<!-- application.hbs -->
<h1>My great app</h1>
{{render "navigation"}}
```
```html
<h1>My great app</h1>
<div class='ember-view'>
Hello, world.
</div>
```
Optionally you may provide a second argument: a property path
that will be bound to the `model` property of the controller.
If a `model` property path is specified, then a new instance of the
controller will be created and `{{render}}` can be used multiple times
with the same name.
For example if you had this `author` template.
```handlebars
<div class="author">
Written by {{firstName}} {{lastName}}.
Total Posts: {{postCount}}
</div>
```
You could render it inside the `post` template using the `render` helper.
```handlebars
<div class="post">
<h1>{{title}}</h1>
<div>{{body}}</div>
{{render "author" author}}
</div>

/**
Ember.Location returns an instance of the correct implementation of
the `location` API.
## Implementations
You can pass an implementation name (`hash`, `history`, `none`) to force a
particular implementation to be used in your application.
### HashLocation
Using `HashLocation` results in URLs with a `#` (hash sign) separating the
server side URL portion of the URL from the portion that is used by Ember.
This relies upon the `hashchange` event existing in the browser.
Example:
```javascript
App.Router.map(function() {
this.resource('posts', function() {
this.route('new');
});
});
App.Router.reopen({
location: 'hash'
});
```
This will result in a posts.new url of `/#/posts/new`.
### HistoryLocation
Using `HistoryLocation` results in URLs that are indistinguishable from a
standard URL. This relies upon the browser's `history` API.
Example:
```javascript
App.Router.map(function() {
this.resource('posts', function() {
this.route('new');
});
});
App.Router.reopen({
location: 'history'
});
```
This will result in a posts.new url of `/posts/new`.
Keep in mind that your server must serve the Ember app at all the routes you
define.
### AutoLocation
Using `AutoLocation`, the router will use the best Location class supported by
the browser it is running in.
Browsers that support the `history` API will use `HistoryLocation`, those that
do not, but still support the `hashchange` event will use `HashLocation`, and
in the rare case neither is supported will use `NoneLocation`.
Example:
```javascript
App.Router.map(function() {
this.resource('posts', function() {
this.route('new');
});
});
App.Router.reopen({
location: 'auto'
});
```
This will result in a posts.new url of `/posts/new` for modern browsers that
support the `history` api or `/#/posts/new` for older ones, like Internet
Explorer 9 and below.
When a user visits a link to your application, they will be automatically
upgraded or downgraded to the appropriate `Location` class, with the URL
transformed accordingly, if needed.
Keep in mind that since some of your users will use `HistoryLocation`, your
server must serve the Ember app at all the routes you define.
### NoneLocation
Using `NoneLocation` causes Ember to not store the applications URL state
in the actual URL. This is generally used for testing purposes, and is one
of the changes made when calling `App.setupForTesting()`.
## Location API
Each location implementation must provide the following methods:
* implementation: returns the string name used to reference the implementation.
* getURL: returns the current URL.
* setURL(path): sets the current URL.
* replaceURL(path): replace the current URL (optional).
* onUpdateURL(callback): triggers the callback when the URL changes.
* formatURL(url): formats `url` to be placed into `href` attribute.
Calling setURL or replaceURL will not trigger onUpdateURL callbacks.

The `willTransition` action is fired at the beginning of any
attempted transition with a `Transition` object as the sole
argument. This action can be used for aborting, redirecting,
or decorating the transition from the currently active routes.
A good example is preventing navigation when a form is
half-filled out:
```js
App.ContactFormRoute = Ember.Route.extend({
actions: {
willTransition: function(transition) {
if (this.controller.get('userHasEnteredData')) {

```
You can also redirect elsewhere by calling
`this.transitionTo('elsewhere')` from within `willTransition`.
Note that `willTransition` will not be fired for the
redirecting `transitionTo`, since `willTransition` doesn't
fire when there is already a transition underway. If you want
subsequent `willTransition` actions to fire for the redirecting
transition, you must first explicitly call
`transition.abort()`.

/**
When attempting to transition into a route, any of the hooks
may return a promise that rejects, at which point an `error`
action will be fired on the partially-entered routes, allowing
for per-route error handling logic, or shared error handling
logic defined on a parent route.
Here is an example of an error handler that will be invoked
for rejected promises from the various hooks on the route,
as well as any unhandled errors from child routes:
```js
App.AdminRoute = Ember.Route.extend({
beforeModel: function() {
return Ember.RSVP.reject("bad things!");
},
actions: {
error: function(error, transition) {
// Assuming we got here due to the error in `beforeModel`,
// we can expect that error === "bad things!",
// but a promise model rejecting would also
// call this hook, as would any errors encountered
// in `afterModel`.
// The `error` hook is also provided the failed
// `transition`, which can be stored and later
// `.retry()`d if desired.
this.transitionTo('login');
}
}
});
```
`error` actions that bubble up all the way to `ApplicationRoute`
will fire a default error handler that logs the error. You can
specify your own global default error handler by overriding the
`error` handler on `ApplicationRoute`:
```js
App.ApplicationRoute = Ember.Route.extend({
actions: {
error: function(error, transition) {
this.controllerFor('banner').displayError(error.message);
}
}
});

Transition the application into another route. The route may

Optionally supply a model for the route in question. The model
will be serialized into the URL using the `serialize` hook of

```javascript

If a literal is passed (such as a number or a string), it will

It is also possible to pass a URL (a string that starts with a
`/`). This is intended for testing and debugging purposes and
should rarely be used in production code.
```javascript
this.transitionTo('/');

/**
This hook is the first of the route entry validation hooks
called when an attempt is made to transition into a route
or one of its children. It is called before `model` and
`afterModel`, and is appropriate for cases when:
1) A decision can be made to redirect elsewhere without
needing to resolve the model first.
2) Any async operations need to occur first before the
model is attempted to be resolved.
This hook is provided the current `transition` attempt
as a parameter, which can be used to `.abort()` the transition,
save it for a later `.retry()`, or retrieve values set
on it from a previous hook. You can also just call
`this.transitionTo` to another route to implicitly
abort the `transition`.
You can return a promise from this hook to pause the
transition until the promise resolves (or rejects). This could
be useful, for instance, for retrieving async code from
the server that is required to enter a route.
```js
App.PostRoute = Ember.Route.extend({
beforeModel: function(transition) {
if (!App.Post) {
return Ember.$.getScript('/models/post.js');
}
}
});
```
If `App.Post` doesn't exist in the above example,
`beforeModel` will use jQuery's `getScript`, which
returns a promise that resolves after the server has
successfully retrieved and executed the code from the
server. Note that if an error were to occur, it would
be passed to the `error` hook on `Ember.Route`, but
it's also possible to handle errors specific to
`beforeModel` right from within the hook (to distinguish
from the shared error handling behavior of the `error`
hook):
```js
App.PostRoute = Ember.Route.extend({
beforeModel: function(transition) {
if (!App.Post) {
var self = this;
return Ember.$.getScript('post.js').then(null, function(e) {
self.transitionTo('help');
// Note that the above transitionTo will implicitly
// halt the transition. If you were to return
// nothing from this promise reject handler,
// according to promise semantics, that would
// convert the reject into a resolve and the
// transition would continue. To propagate the
// error so that it'd be handled by the `error`
// hook, you would have to either
return Ember.RSVP.reject(e);
});
}
}
});

`model`, and `afterModel` hooks being fired again within
the new, redirecting transition. Redirects that occur within

A hook you can implement to convert the URL into the model for

```js
App.Router.map(function() {

```
The model for the `post` route is `App.Post.find(params.post_id)`.
By default, if your route has a dynamic segment ending in `_id`:
* The model class is determined from the segment (`post_id`'s
class is `App.Post`)
* The find method is called on the model class with the value of
the dynamic segment.
Note that for routes with dynamic segments, this hook is only
executed when entered via the URL. If the route is entered
through a transition (e.g. when using the `link-to` Handlebars
helper), then a model context is already provided and this hook
is not called. Routes without dynamic segments will always
execute the model hook.
This hook follows the asynchronous/promise semantics
described in the documentation for `beforeModel`. In particular,
if a promise returned from `model` fails, the error will be
handled by the `error` hook on `Ember.Route`.

App.PostRoute = Ember.Route.extend({

A hook you can use to setup the controller for the current route.
This method is called with the controller for the current route and the
model supplied by the `model` hook.
By default, the `setupController` hook sets the `model` property of
the controller to the `model`.
If you implement the `setupController` hook in your Route, it will
prevent this default behavior. If you want to preserve that behavior
when implementing your `setupController` function, make sure to call
`_super`:
```js
App.PhotosRoute = Ember.Route.extend({
model: function() {
return App.Photo.find();
},
setupController: function (controller, model) {
// Call _super for default behavior
this._super(controller, model);
// Implement your custom setup after
this.controllerFor('application').set('showingPhotos', true);
}
});
```
This means that your template will get a proxy for the model as its
context, and you can act as though the model itself was the context.
The provided controller will be one resolved based on the name
of this route.
If no explicit controller is defined, Ember will automatically create
an appropriate controller for the model.
* if the model is an `Ember.Array` (including record arrays from Ember
Data), the controller is an `Ember.ArrayController`.
* otherwise, the controller is an `Ember.ObjectController`.
As an example, consider the router:
```js
App.Router.map(function() {
this.resource('post', {path: '/posts/:post_id'});
});
```
For the `post` route, a controller named `App.PostController` would
be used if it is defined. If it is not defined, an `Ember.ObjectController`
instance would be used.
Example
```js
App.PostRoute = Ember.Route.extend({
setupController: function(controller, model) {
controller.set('model', model);
}
});

A hook you can use to render the template for the current route.

This method can be overridden to set up and render additional or
alternative templates.
```js
App.PostsRoute = Ember.Route.extend({
renderTemplate: function(controller, model) {
var favController = this.controllerFor('favoritePost');
// Render the `favoritePost` template into
// the outlet `posts`, and display the `favoritePost`

Renders a template into an outlet.
This method has a number of defaults, based on the name of the
route specified in the router.
For example:
```js
App.Router.map(function() {
this.route('index');
this.resource('post', {path: '/posts/:post_id'});
});
App.PostRoute = App.Route.extend({
renderTemplate: function() {
this.render();
}
});
```
The name of the `PostRoute`, as defined by the router, is `post`.
By default, render will:
* render the `post` template
* with the `post` view (`PostView`) for event handling, if one exists
* and the `post` controller (`PostController`), if one exists
* into the `main` outlet of the `application` template
You can override this behavior:
```js
App.PostRoute = App.Route.extend({
renderTemplate: function() {
this.render('myPost', { // the template to render
into: 'index', // the template to render into
outlet: 'detail', // the name of the outlet in that template
controller: 'blogPost' // the controller to use for the template
});
}
});
```
Remember that the controller's `model` will be the route's model. In
this case, the default model will be `App.Post.find(params.post_id)`.

/**
Creates a computed property which operates on dependent arrays and
is updated with "one at a time" semantics. When items are added or
removed from the dependent array(s) an array computed only operates
on the change instead of re-evaluating the entire array. This should
return an array, if you'd like to use "one at a time" semantics and
compute some value other then an array look at
`Ember.reduceComputed`.
If there are more than one arguments the first arguments are
considered to be dependent property keys. The last argument is
required to be an options object. The options object can have the
following three properties.
`initialize` - An optional initialize function. Typically this will be used
to set up state on the instanceMeta object.
`removedItem` - A function that is called each time an element is
removed from the array.
`addedItem` - A function that is called each time an element is
added to the array.
The `initialize` function has the following signature:
```javascript
function (array, changeMeta, instanceMeta)
```
`array` - The initial value of the arrayComputed, an empty array.
`changeMeta` - An object which contains meta information about the
computed. It contains the following properties:
- `property` the computed property
- `propertyName` the name of the property on the object
`instanceMeta` - An object that can be used to store meta
information needed for calculating your computed. For example a
unique computed might use this to store the number of times a given
element is found in the dependent array.
The `removedItem` and `addedItem` functions both have the following signature:
```javascript
function (accumulatedValue, item, changeMeta, instanceMeta)
```
`accumulatedValue` - The value returned from the last time
`removedItem` or `addedItem` was called or an empty array.
`item` - the element added or removed from the array
`changeMeta` - An object which contains meta information about the
change. It contains the following properties:
- `property` the computed property
- `propertyName` the name of the property on the object
- `index` the index of the added or removed item
- `item` the added or removed item: this is exactly the same as
the second arg
- `arrayChanged` the array that triggered the change. Can be
useful when depending on multiple arrays.
For property changes triggered on an item property change (when
depKey is something like `someArray.@each.someProperty`),
`changeMeta` will also contain the following property:
- `previousValues` an object whose keys are the properties that changed on
the item, and whose values are the item's previous values.
`previousValues` is important Ember coalesces item property changes via
Ember.run.once. This means that by the time removedItem gets called, item has
the new values, but you may need the previous value (eg for sorting &
filtering).
`instanceMeta` - An object that can be used to store meta
information needed for calculating your computed. For example a
unique computed might use this to store the number of times a given
element is found in the dependent array.
The `removedItem` and `addedItem` functions should return the accumulated
value. It is acceptable to not return anything (ie return undefined)
to invalidate the computation. This is generally not a good idea for
arrayComputed but it's used in eg max and min.
Example
```javascript
Ember.computed.map = function(dependentKey, callback) {
var options = {
addedItem: function(array, item, changeMeta, instanceMeta) {
var mapped = callback(item);
array.insertAt(changeMeta.index, mapped);
return array;
},
removedItem: function(array, item, changeMeta, instanceMeta) {
array.removeAt(changeMeta.index, 1);
return array;
}
};
return Ember.arrayComputed(dependentKey, options);
};

/**
Creates a computed property which operates on dependent arrays and
is updated with "one at a time" semantics. When items are added or
removed from the dependent array(s) a reduce computed only operates
on the change instead of re-evaluating the entire array.
If there are more than one arguments the first arguments are
considered to be dependent property keys. The last argument is
required to be an options object. The options object can have the
following four properties:
`initialValue` - A value or function that will be used as the initial
value for the computed. If this property is a function the result of calling
the function will be used as the initial value. This property is required.
`initialize` - An optional initialize function. Typically this will be used
to set up state on the instanceMeta object.
`removedItem` - A function that is called each time an element is removed
from the array.
`addedItem` - A function that is called each time an element is added to
the array.
The `initialize` function has the following signature:
```javascript
function (initialValue, changeMeta, instanceMeta)
```
`initialValue` - The value of the `initialValue` property from the
options object.
`changeMeta` - An object which contains meta information about the
computed. It contains the following properties:
- `property` the computed property
- `propertyName` the name of the property on the object
`instanceMeta` - An object that can be used to store meta
information needed for calculating your computed. For example a
unique computed might use this to store the number of times a given
element is found in the dependent array.
The `removedItem` and `addedItem` functions both have the following signature:
```javascript
function (accumulatedValue, item, changeMeta, instanceMeta)
```
`accumulatedValue` - The value returned from the last time
`removedItem` or `addedItem` was called or `initialValue`.
`item` - the element added or removed from the array
`changeMeta` - An object which contains meta information about the
change. It contains the following properties:
- `property` the computed property
- `propertyName` the name of the property on the object
- `index` the index of the added or removed item
- `item` the added or removed item: this is exactly the same as
the second arg
- `arrayChanged` the array that triggered the change. Can be
useful when depending on multiple arrays.
For property changes triggered on an item property change (when
depKey is something like `someArray.@each.someProperty`),
`changeMeta` will also contain the following property:
- `previousValues` an object whose keys are the properties that changed on
the item, and whose values are the item's previous values.
`previousValues` is important Ember coalesces item property changes via
Ember.run.once. This means that by the time removedItem gets called, item has
the new values, but you may need the previous value (eg for sorting &
filtering).
`instanceMeta` - An object that can be used to store meta
information needed for calculating your computed. For example a
unique computed might use this to store the number of times a given
element is found in the dependent array.
The `removedItem` and `addedItem` functions should return the accumulated
value. It is acceptable to not return anything (ie return undefined)
to invalidate the computation. This is generally not a good idea for
arrayComputed but it's used in eg max and min.
Note that observers will be fired if either of these functions return a value
that differs from the accumulated value. When returning an object that
mutates in response to array changes, for example an array that maps
everything from some other array (see `Ember.computed.map`), it is usually
important that the *same* array be returned to avoid accidentally triggering observers.
Example
```javascript
Ember.computed.max = function (dependentKey) {
return Ember.reduceComputed(dependentKey, {
initialValue: -Infinity,
addedItem: function (accumulatedValue, item, changeMeta, instanceMeta) {
return Math.max(accumulatedValue, item);
},
removedItem: function (accumulatedValue, item, changeMeta, instanceMeta) {
if (item < accumulatedValue) {
return accumulatedValue;
}
}
});
};
```
Dependent keys may refer to `@this` to observe changes to the object itself,
which must be array-like, rather than a property of the object. This is
mostly useful for array proxies, to ensure objects are retrieved via
`objectAtContent`. This is how you could sort items by properties defined on an item controller.
Example
```javascript
App.PeopleController = Ember.ArrayController.extend({
itemController: 'person',
sortedPeople: Ember.computed.sort('@this.@each.reversedName', function(personA, personB) {
// `reversedName` isn't defined on Person, but we have access to it via
// the item controller App.PersonController. If we'd used
// `content.@each.reversedName` above, we would be getting the objects
// directly and not have access to `reversedName`.
//
var reversedNameA = get(personA, 'reversedName'),
reversedNameB = get(personB, 'reversedName');
return Ember.compare(reversedNameA, reversedNameB);
})
});
App.PersonController = Ember.ObjectController.extend({
reversedName: function () {
return reverse(get(this, 'name'));
}.property('name')
})
```
Dependent keys whose values are not arrays are treated as regular
dependencies: when they change, the computed property is completely
recalculated. It is sometimes useful to have dependent arrays with similar
semantics. Dependent keys which end in `.[]` do not use "one at a time"
semantics. When an item is added or removed from such a dependency, the
computed property is completely recomputed.
When the computed property is completely recomputed, the `accumulatedValue`
is discarded, it starts with `initialValue` again, and each item is passed
to `addedItem` in turn.
Example
```javascript
Ember.Object.extend({
// When `string` is changed, `computed` is completely recomputed.
string: 'a string',
// When an item is added to `array`, `addedItem` is called.
array: [],
// When an item is added to `anotherArray`, `computed` is completely
// recomputed.
anotherArray: [],
computed: Ember.reduceComputed('string', 'array', 'anotherArray.[]', {
addedItem: addedItemCallback,
removedItem: removedItemCallback
})
});
```

The callback method you provide should have the following signature:

- `itemA` the first item to compare.
- `itemB` the second item to compare.
This function should return negative number (e.g. `-1`) when `itemA` should come before
`itemB`. It should return positive number (e.g. `1`) when `itemA` should come after
`itemB`. If the `itemA` and `itemB` are equal this function should return `0`.
Therefore, if this function is comparing some numeric values, simple `itemA - itemB` or
`itemA.get( 'foo' ) - itemB.get( 'foo' )` can be used instead of series of `if`.

```javascript

/**
`Ember.ArrayController` provides a way for you to publish a collection of
objects so that you can easily bind to the collection from a Handlebars
`#each` helper, an `Ember.CollectionView`, or other controllers.
The advantage of using an `ArrayController` is that you only have to set up
your view bindings once; to change what's displayed, simply swap out the
`model` property on the controller.
For example, imagine you wanted to display a list of items fetched via an XHR
request. Create an `Ember.ArrayController` and set its `model` property:
```javascript
MyApp.listController = Ember.ArrayController.create();
$.get('people.json', function(data) {
MyApp.listController.set('model', data);
});
```
Then, create a view that binds to your new controller:
```handlebars
{{#each MyApp.listController}}
{{firstName}} {{lastName}}
{{/each}}
```
Although you are binding to the controller, the behavior of this controller
is to pass through any methods or properties to the underlying array. This
capability comes from `Ember.ArrayProxy`, which this class inherits from.
Sometimes you want to display computed properties within the body of an
`#each` helper that depend on the underlying items in `model`, but are not
present on those items. To do this, set `itemController` to the name of a
controller (probably an `ObjectController`) that will wrap each individual item.
For example:
```handlebars
{{#each post in controller}}
<li>{{post.title}} ({{post.titleLength}} characters)</li>
{{/each}}
```
```javascript
App.PostsController = Ember.ArrayController.extend({
itemController: 'post'
});
App.PostController = Ember.ObjectController.extend({
// the `title` property will be proxied to the underlying post.
titleLength: function() {
return this.get('title').length;
}.property('title')
});
```
In some cases it is helpful to return a different `itemController` depending
on the particular item. Subclasses can do this by overriding
`lookupItemController`.
For example:
```javascript
App.MyArrayController = Ember.ArrayController.extend({
lookupItemController: function( object ) {
if (object.get('isSpecial')) {
return "special"; // use App.SpecialController
} else {
return "regular"; // use App.RegularController
}
}
});
```
The itemController instances will have a `parentController` property set to
the `ArrayController` instance.

The `property` extension of Javascript's Function prototype is available
when `Ember.EXTEND_PROTOTYPES` or `Ember.EXTEND_PROTOTYPES.Function` is
`true`, which is the default.
Computed properties allow you to treat a function like a property:
```javascript
MyApp.President = Ember.Object.extend({
firstName: '',
lastName: '',
fullName: function() {
return this.get('firstName') + ' ' + this.get('lastName');
// Call this flag to mark the function as a property
}.property()
});
var president = MyApp.President.create({
firstName: "Barack",
lastName: "Obama"
});
president.get('fullName'); // "Barack Obama"
```
Treating a function like a property is useful because they can work with
bindings, just like any other property.
Many computed properties have dependencies on other properties. For
example, in the above example, the `fullName` property depends on
`firstName` and `lastName` to determine its value. You can tell Ember
about these dependencies like this:
```javascript
MyApp.President = Ember.Object.extend({
firstName: '',
lastName: '',
fullName: function() {
return this.get('firstName') + ' ' + this.get('lastName');
// Tell Ember.js that this computed property depends on firstName
// and lastName
}.property('firstName', 'lastName')
});
```
Make sure you list these dependencies so Ember knows when to update
bindings that connect to a computed property. Changing a dependency
will not immediately trigger an update of the computed property, but
will instead clear the cache so that it is updated when the next `get`
is called on the property.

`Ember.Route`, `Ember.View`, `Ember.Component`, and controllers such as
`Ember.Controller` and `Ember.ObjectController`.
(Internally the mixin is used by `Ember.CoreView`, `Ember.ControllerMixin`,
and `Ember.Route` and available to the above classes through
inheritance.)
@class ActionHandler

*/
var ActionHandler = Mixin.create({
mergedProperties: ['_actions'],
/**
The collection of functions, keyed by name, available on this
`ActionHandler` as action targets.
These functions will be invoked when a matching `{{action}}` is triggered
from within a template and the application's current route is this route.
Actions can also be invoked from other parts of your application
via `ActionHandler#send`.
The `actions` hash will inherit action handlers from
the `actions` hash defined on extended parent classes
or mixins rather than just replace the entire hash, e.g.:
```js
App.CanDisplayBanner = Ember.Mixin.create({
actions: {
displayBanner: function(msg) {
// ...
}
}
});
App.WelcomeRoute = Ember.Route.extend(App.CanDisplayBanner, {
actions: {
playMusic: function() {
// ...
}
}
});
// `WelcomeRoute`, when active, will be able to respond
// to both actions, since the actions hash is merged rather
// then replaced when extending mixins / parent classes.
this.send('displayBanner');
this.send('playMusic');
```
Within a Controller, Route, View or Component's action handler,
the value of the `this` context is the Controller, Route, View or
Component object:
```js
App.SongRoute = Ember.Route.extend({
actions: {
myAction: function() {
this.controllerFor("song");
this.transitionTo("other.route");
...
}
}
});
```
It is also possible to call `this._super()` from within an
action handler if it overrides a handler defined on a parent
class or mixin:
Take for example the following routes:
```js
App.DebugRoute = Ember.Mixin.create({
actions: {
debugRouteInformation: function() {
console.debug("trololo");
}
}
});
App.AnnoyingDebugRoute = Ember.Route.extend(App.DebugRoute, {
actions: {
debugRouteInformation: function() {
// also call the debugRouteInformation of mixed in App.DebugRoute
this._super();
// show additional annoyance
window.alert(...);
}
}
});
```
## Bubbling
By default, an action will stop bubbling once a handler defined
on the `actions` hash handles it. To continue bubbling the action,
you must return `true` from the handler:
```js
App.Router.map(function() {
this.resource("album", function() {
this.route("song");
});
});
App.AlbumRoute = Ember.Route.extend({
actions: {
startPlaying: function() {
}
}
});
App.AlbumSongRoute = Ember.Route.extend({
actions: {
startPlaying: function() {
// ...
if (actionShouldAlsoBeTriggeredOnParentRoute) {
return true;
}
}
}
});
```

/**
This mixin implements Observer-friendly Array-like behavior. It is not a
concrete implementation, but it can be used up by other classes that want
to appear like arrays.
For example, ArrayProxy and ArrayController are both concrete classes that can
be instantiated to implement array-like behavior. Both of these classes use
the Array Mixin by way of the MutableArray mixin, which allows observable
changes to be made to the underlying array.
Unlike `Ember.Enumerable,` this mixin defines methods specifically for
collections that provide index-ordered access to their contents. When you
are designing code that needs to accept any kind of Array-like object, you
should use these methods instead of Array primitives because these will
properly notify observers of changes to the array.
Although these methods are efficient, they do add a layer of indirection to
your application so it is a good idea to use them only when you need the
flexibility of using both true JavaScript arrays and "virtual" arrays such
as controllers and collections.
You can use the methods defined in this module to access and modify array
contents in a KVO-friendly way. You can also be notified whenever the
membership of an array changes by using `.observes('myArray.[]')`.
To support `Ember.Array` in your own class, you must override two
primitives to use it: `replace()` and `objectAt()`.
Note that the Ember.Array mixin also incorporates the `Ember.Enumerable`
mixin. All `Ember.Array`-like objects are also enumerable.

Both callbacks will be passed the observed object, starting index of the
change as well a a count of the items to be removed and added. You can use
these callbacks to optionally inspect the array during the change, clear
caches, or do any other bookkeeping necessary.

which you can use to override the method names that will be invoked on the
target.
