Confusion about naming conventions in emberjs

Perhaps some folks just know the answer, but I am trying to understand the following:

Say you are declaring a view:

App.FooView = Ember.View.extend({});

Now referencing this view in App.Router results in the following error:

router.get('applicationController').connectOutlet('Foo')

When I reference Foo the console states: Uncaught Error: assertion failed: The name you supplied Foo did not resolve to a controller FooController

I could not find anywhere in the docs explaining the args. Perhaps the person who downvoted could actually contribute to the solution.

When you connect an outlet, the router looks for both a controller and a view the having the same name as the one supplied. In the example you listed, the router is looking for a FooController and a FooView, and is not finding the controller. If you would like to specify more details you can pass an options object with the view, controller and context, like so:

router.get('applicationController').connectOutlet( {
           outletName: 'master',
           controller: 'fooController',
           view: 'fooView',
           context: data
        });

From the documentation:

connectOutlet: function(name, context) {
// Normalize arguments. Supported arguments:
//
// name
// name, context
// outletName, name
// outletName, name, context
// options
//
// The options hash has the following keys:
//
//   name: the name of the controller and view
//     to use. If this is passed, the name
//     determines the view and controller.
//   outletName: the name of the outlet to
//     fill in. default: 'view'
//   viewClass: the class of the view to instantiate
//   controller: the controller instance to pass
//     to the view
//   context: an object that should become the
//     controller's `content` and thus the
//     template's context.

edit: grammar and code format
