Accessing Ember-CLI Nested Controllers

This is my directory structure:

---- restaurant/
---- index.js
---- restaurant.js

And my router declaration:

path: "/restaurants"

this.resource("restaurant", {
path: "/restaurants/:restaurant_id"
}, function() {
this.resource("items", {
path: "/items"

My Items controller (located in restaurants/items.js) begins with the following:

export default Ember.ObjectController.extend({
needs: ["restaurant"],
restaurant: Ember.computed.alias('')

and is then followed by an action to add the item under hte restaurant.

However, I keep getting hte error saying "restaurant" needs to be added to "needs":

ReferenceError: (generated items controller)#needs does not include
. To access the restaurant controller from (generated items controller), (generated items controller) should have a
property that is an array of the controllers it has access to

This is my setup (Ember-CLI 0.1.2 with Ember 1.7) - As i'm using the fireplace adapter to work with firebase, I don't think it supports upgrading Ember (from what I've tried).

DEBUG: -------------------------------
DEBUG: Ember : 1.7.0"
DEBUG: Ember Data : 1.0.0-beta.10"
DEBUG: Handlebars : 1.3.0"
DEBUG: jQuery : 1.11.2"
DEBUG: Fireplace : 0.2.9"
DEBUG: -------------------------------

I've tried the other Stackoverflow answers (e.g. How to communicate between controllers in Ember.js) but they don't seem to help.

Does anyone know what's going on here? Thanks!

As of Ember-CLI v0.2.1 + Ember v1.10.0 (could work for earlier versions; but I haven't tried), this is how you do it:

export default Ember.ObjectController.extend({
    needs: ["restaurant/items"],

To access actions, you'd do this:

actions: {
    myAction: function(arg1, arg2) {
      this.get('').send('someItemActionYouDefine', arg1, arg2);
