Uncaught TypeError: Cannot call method ‘map’ of undefined

这是coffescript代码：

window.Cosmetics = Ember.Application.create

Cosmetics.store = DS.Store.create
  revision: 4
  adapter: DS.RESTAdapter.create 
    bulkCommit: false

Cosmetics.admin_user = DS.Model.extend({
  name: DS.attr('string')
  email: DS.attr('string')
});

Cosmetics.view = Ember.View.extend
  templateName: 'ember/views/aaa'

Cosmetics.admin_user.reopenClass
  url: 'admin/user'

Cosmetics.store.findAll(Cosmetics.admin_user)

Controller获取正确的JSON数据.我已经尝试从互联网上找到的示例中映射代码,但没有任何帮助.有任何想法吗？我想我做错了.在此先感谢您的帮助.
