  body: DS.attr("string")

  validate: ->
    if @get("title") is `undefined` or @get("title") is "" or @get("body") is `undefined` or @get("body") is ""

post_serializer.rb

class PostSerializer < ActiveModel::Serializer
  embed :ids, :include => true
  attributes :title, :body, :id
  has_many :comments
end

comment = App.store.find(App.Comment,1)
JSON.stringify(comment)
"{"id":1,"body":"wheeeee","post_id":1}"

Ahh. So this is the syntax

JSON.stringify(post.get('comments').objectAt(0))
"{"id":1,"body":"wheeeee","post_id":1}"
