Ember.js get controller of parent route using Router architecture

Question

If I have an application using the Router architecture , how do I get the controller of the parent route?

suppose a route like

Router: Ember.Router.extend 
    enableLogging: true
    root: Ember.Route.extend
        main: Ember.Route.extend
            route: '/'
            connectOutlets: (router, event) ->
                 router.get('applicationController').connectOutlet('main')
            editor: Ember.Route.extend
                route: '/editor'
                connectOutlets: (router, event) ->
                    router.get('mainController').connectOutlet('editor')

So how would my EditorController get a hold of my MainController ?

I've tried @get('parentController') , @get('parent') , and @get('controller') with no success

Answer 1

You can access the router through the target property of a controller.

eg, in your case, from any controller:

@get('target.mainController')

Or, if you do not use head revision of Ember:

@getPath('target.mainController')

According to my understanding, an application is supposed to have only one router, so why dont we just do:

@get('App.router.mainController')

I have no idea on what is the right approach! I feel like 'target' is storing the object to which actions or events are dispatched.
