Ember.js pre4 router get other controllers

Question

Possible Duplicate:
Accessing controllers from other controllers

In Ember pre2 and before with the old Router style, you could get other controllers from the router, so if I were in a controller called PeopleController I could do something like this

App.PeopleController = Ember.Controller.extend({
     some_computed_property: (function() {
          return this.get('target.otherController.property_i_want');
     }).property('target.otherController.property_i_want')
});

or from a debug console

> App.router.get('otherController.property_i_want')

Both of these worked. Pre4 / the new routing style seems to break this. How do I get this functionality with the new router and pre4?

I asked a similar question; you can declare dependencies in the current version.

I had a horrible hack:

Em.Route.reopen({init:function(){
  window.App.currentRoute = this;
  this._super.apply(this,arguments);
}})

Which lets you do things like:

App.currentRoute.controllerFor('something');
App.currentRoute.target...

EDIT: Currently, ember supports defining "needs" for controllers, as well as exposes the container for lookups:

App.__container__.lookup("controller:application").get("someProperty")

App.ApplicationController = Em.Controller.extend({
    needs: ["authentication","notifications"],
    init: function(){
       this._super.apply(this,arguments)
       console.log(this.get("controllers.authentication"), this.get("controllers.notifications"))
    }
})

That's clever, I like that :) – wmarbut Jan 23 '13 at 15:38 — wmarbut, Jan 23 '13 at 15:38

Try this.controllerFor('other').get('property_i_want')

See last part of http://emberjs.com/guides/routing/setting-up-a-controller/

Thanks! This works within a controller, but not from the debug console. – wmarbut Jan 22 '13 at 21:30
This also doesn't provide a way to handle the `.property('target.otherController.property_i_want')` – wmarbut Jan 22 '13 at 22:30

To access the controller from the console, set debugger; in your code, refresh the browser, that will halt execution where you set the debugger statement, then you can access your controller within the scope you're in, using

this.controllerFor('abs');

This also very useful in debugging template, you can insert {{debugger;}} and that gives you access to the whole scope of the template in the console, try for example to find out what your controller or your view are.
