It All Starts With Templates

An Ember application starts with its main template. Put your header, footer, and any other decorative content in application.handlebars.

<header>

Recently, we've been working on extracting Ember conventions from applications we're working on into the framework. Our goal is to make it clearer how the parts of an Ember application work together, and how to organize and bootstrap your objects.

Routing

Routing is an important part of web applications. It allows your users to share the URL they see in their browser, and have the same things appear when their friends click on the link.

The Ember.js ecosystem has several great solutions for routing. But, since it is such an important part of most web applications, we've decided to build it right into the framework.

If you have already modeled your application state using Ember.StateManager, there are a few changes you'll need to make to enable routing. Once you've made those changes, you'll notice the browser's address bar spring to life as you start using your app—just by moving between states, Ember.js will update the URL automatically.

Routing in Ember

In Ember, the application's state manager handles routing. Let's take a look at a simple example:

App.stateManager = Ember.StateManager.create({
  start: Ember.State.extend({
    index: Ember.State.extend({
      route: "/",

View Context Changes

The rules for how Ember.js evaluates Handlebars templates have recently changed, and you may need to update your application's templates to ensure they continue working..

Template Contexts

Remember that a template is always evaluated against a context object. When you render a template, values are looked up from that object. For example:

Hello, {{firstName}} {{lastName}}!

Polymorphic Associations reversed

It's pretty easy to do polymorphic associations in Rails: A Picture can belong to either a BlogPost or an Article. But what if you need the relationship the other way around? A Picture, a Text and a Video can belong to an Article, and that article can find all media by calling @article.media

This example shows how to create an ArticleElement join model that handles the polymorphic relationship. To add fields that are common to all polymorphic models, add fields to the join model.
