Nested PromiseProxyMixin Properties


I have the following (simplified for this example) data model.

// org.js
export default DS.Model.extend({
  profile: DS.belongsTo('organizations/profile',{ async: true }),

// profile.js
export default DS.Model.extend({
	orgName: DS.attr('string'),
	address: DS.belongsTo('address',{ async: true}),
	org: DS.belongsTo('organizations/org',{ async: true}),

// address.js
export default DS.Model.extend({
    address1: DS.attr('string')

I’d like to create an object after loading the org which will contain computed properties based on the nested async data model. Something like this:

var Marker = Ember.Object.extend({
	id: Ember.computed.alias(''),
	title: Ember.computed.alias('org.profile.orgName'),
	lat: Ember.computed.alias(''),
	lng: Ember.computed.alias('org.profile.address.lng'),
	isDraggable: false

return {
	return Marker.create({ org: org })

This seems to work ok for the title, but for the nested address fields I always get undefined. I think that ideally the Ember.computed.alias helper should just work for nested PromiseObjects but since it doesn’t the only way I can think to do this is to manually wire up then to the profile and address. :frowning:
