Ember.js Optional Route Parameters

A topic that comes up quite often in Ember.js discussion forums is optional route parameters. Unfortunately for those who have this problem, there's no built-in way to achieve this functionality. But there is a very nice little hack that will emulate optional route parameters for most sitautions. The actual method is pretty simple, it just requires combining a few tricks. I'll describe the high-level deatils here, and you can find working example code below.

What's needed to pull this off:

1. You'll need a resource with a sub-route. The sub-route is the 'real' route that you're going to use. All of your logic should be declared in the controller and template for this route. (Also remember that using a resource generates an implicit index route.)
2. The implicit index route is where you should redirect to if you have no model to provide. It's also where you end up if you go to a URL without providing the parameter. This route immediately redirects to your other sub-r

// tests/acceptance/foo-test.js

// Assert that text should be found
assert.hasText('Not Found'); // Error: Could not find text "Not Found" on the page

// Provide custom message
assert.hasText('Not Found', 'Expected to find "Not Found"'); // Error: Expected to find "Not Found"

// Find any number of elements containing the query text
text('Found'); // [<div>Found</div>, <input value="Found">]
