Any method for accessing parent object properties in Ember?

This question shows how to get properties of parent views.

Is there a way to achieve the same with general Ember.Objects. For example how does the child access properties of App.Parent:

App.Parent = Ember.Object.extend({
  parentProperty: 'someValue',

  child: App.Child.create()  

});

App.Child = Ember.Object.extend({
   init: function(){
     // I don't know which is my parent object
     // but I still want to access the value of `parentProperty`
     // var parentProperty = ???

   }
});

I put together a jsfiddle demonstrating how to update a child object with a "parent" property. The basic idea is check for the presence of a child on creation of the parent, and watch in case the child changes.

Hopefully, it will help. Comment here is you have any questions.

Can you pass the parent in when you create the child?

App.Parent = Ember.Object.extend({
  parentProperty: 'someValue',

  child: App.Child.create({ parent: App.Parent })  
})
