Question

I want to use this.get(\'controllers.pack.query\'); to get App.PackQueryController in App.PackController, but failed.

I think

Answer 1

Ember.inject.controller() should be used to access a controller. Use it like so:

Setting

...
myController: Ember.inject.controller('pack'),
nestedController: Ember.inject.controller('pack/query')
...

Getting

...
this.get('myController');
this.get('nestedController');
...

The answer above was updated to reflect the needs deprecation in Ember 1.13.5 (released July 19, 2015). I've left the old answers below, but shouldn't be used unless you're using an older version of Ember.

[DEPRECATED] Accessing nested controllers from other controllers using needs:

Set needs on the controller:

...
needs: ['pack/query'],
...

Then access it using:

this.get('controllers.pack/query');

[DEPRECATED] Accessing nested controllers from routes:

Ideally, actions should be put on a Route. If you're using the needs pattern outlined above in your actions on a controller, consider refactoring.

You can access nested controllers from a Route using controllerFor like so:

this.controllerFor('pack/query')
