title: Ember data multi level hierarchy with embedded always
body: <p>I am able to use embedded always for one level but I am unable to use it for two level deep model. Need an urgent help </p>
  
  <pre><code>App.Post = DS.Model.extend(
    title: DS.attr("string")
    comment: DS.belongsTo("App.Comment")
  )
  
  App.Comment = DS.Model.extend(
    text: DS.attr("string")
    ferment: DS.belongsTo("App.Ferment") 
  )
  
  App.Ferment = DS.Model.extend(
    fermenter: DS.attr("string")
  )
  
  App.Adapter.map App.Post,
    'comment':
      embedded: "always"
  
  
  App.Adapter.map App.Comment,    
    ferment :
      embedded: "always"
  
  # -----------------------------
  App.store = App.Store.create(
    adapter: App.Adapter.create()
  )
  # -----------------------------
  
  App.store.adapter.load App.store, App.Post,
    id: 12
    comment: {text: "blabla", ferment:{fermenter:'abcd'}}
  
  console.log App.Post.find(12).get("comment.text")
  console.log App.Post.find(12).get("comment.ferment.fermenter")
  </code></pre>
  
  <p>I get log for comment.text as blabla
  But cannot get second part to work.
  I am using revision 11 of Ember data store.
  Any one with similar problem/solution.</p>
  
  <p>Interestingly we tried hasMany so Post -hasMany-> Comments, Comment -hasOne-> Ferment. This works fine, here is the code.</p>
  
  <pre><code>App.Post = DS.Model.extend(
    title: DS.attr("string")
    comments: DS.hasMany("App.Comment")
  )
  
  App.Comment = DS.Model.extend(
    text: DS.attr("string")
    ferment: DS.belongsTo("App.Ferment")
  )
  
  App.Ferment = DS.Model.extend(
    fermi: DS.attr("string")
  )
  
  App.Adapter.map App.Post,
    comments:
      embedded: "always"
  
  App.Adapter.map App.Comment,
    ferment:
      embedded: "always"
  
  App.store = App.Store.create(
    adapter: App.Adapter.create()
  )
  
  # App.store.adapter.serializer.configure(App.Comment,
  #   sideloadAs: 'comments' 
  # )
  App.store.adapter.load App.store, App.Post,
    id: 12
    comments: [{text: "blabla", ferment:{fermi: "found fermi"}}]
  
  console.log App.Post.find(12).get("comments.firstObject.text")
  console.log App.Post.find(12).get("comments.firstObject.ferment.fermi")
  </code></pre>
