9.7.1）带有余烬数据（最新的主人），我遇到了一个奇怪的问题。我有一个嵌入的关系：

App.Person = DS.Model.extend({
  ...
  portions: DS.hasMany("App.PersonPortion", { embedded: true}),
  ...
  portionCount: function() {
    return this.get('person_portions').get('length')
  }.property("person_portions.@each")  //This line is the problem.  If I remove "person_portions.@each" it will load correctly
})

person 的 JSON 如下所示：

{"age":null,
 "created_at":"2012-03-24T09:15:31Z",
 "diet_id":5,
 "id":1,
 "lactating":false,
 "name":"cool Name new",
 "pregnant":false,
 "sex":"F","updated_at":"2012-03-27T15:44:03Z",
 "portions":[{"created_at":"2012-04-12T14:54:49Z","crop_id":1,"id":13,"person_id":1,"portion":50,"unit":"grams","updated_at":"2012-04-25T00:41:36Z"},{"created_at":"2012-04-25T00:57:43Z","crop_id":16,"id":20,"person_id":1,"portion":null,"unit":null,"updated_at":"2012-04-26T12:13:48Z"},{"created_at":"2012-04-26T12:13:27Z","crop_id":6,"id":62,"person_id":1,"portion":null,"unit":null,"updated_at":"2012-04-26T12:16:38Z"}]}

但是，当我加载人员时，App.store.find(App.Person, 1)Ember 仍然尝试从服务器加载“部分”关系。这是来自 Chrome 控制台：

GET http://localhost:3000/person_portions?ids%5B0%5D%5Bcreated_at%5D=2012-04-12T14%3A54%3A49Z&ids%5B0%5D%5Bcrop_id%5D=1&ids%5B0%5D%5Bid%5D=13&ids%5B0%5D%5Bperson_id%5D=1&ids%5B0%5D%5Bportion%5D=50&ids%5B0%5D%5Bunit%5D=grams&ids%5B0%5D%5Bupdated_at%5D=2012-04-25T00%3A41%3A36Z

关于我可能做错了什么或者这是一个错误的任何想法？
