在ember.js中遇到奇怪的问题：

TypeError: Object Status has no method 'eachRelatedType'

at Object.DeferredActionQueues.flush (http://localhost:5000/assets/ember.js?body=1:5894:24)

当我的代码尝试显示状态列表时：

window.App = Ember.Application.create()

App.Status = DS.Model.extend
  body: DS.attr('string')

App.StatusesRoute = Ember.Route.extend
 model: ->
    @get('store').findAll 'Status'

App.Router.map ()->
   @resource 'statuses'

DS.RESTAdapter.reopen({ namespace: "api/v1" });

DS.RESTAdapter.configure("plurals", {
  status: "statuses"
});

App.Store = DS.Store.extend
 revision: 12
 adapter: DS.RESTAdapter.create() 

模板：

状态。把手： 条目

状态。把手： {{body}}

Json:

版本：

DEBUG: Ember      : 1.4.0 ember.js?body=1:3462
DEBUG: Handlebars : 1.3.0 ember.js?body=1:3462
DEBUG: jQuery     : 1.10.2 

有人能看出我做错了什么吗？真的很难对付这一点，一定很简单：）

谢谢你

通过将ember数据库更新至最新版本，解决了这一问题

{"statuses":[{"id":2,"body":"Test","user_id":3}]}

DEBUG: Ember      : 1.4.0 ember.js?body=1:3462
