Question

我正在使用Ember Data 1.0.0-beta1和EmberJS 1.0.0。

我的保存操作

App.UsersNewController = Ember.ObjectController.extend({
  actions: {
    save: function() {
      var self = this;
      self.content.save().then(function() {
        self.transitionToRoute('index');
      });
    },

    cancel: function() {
      this.content.deleteRecord();
      this.transitionToRoute('index');
    }
  }
});

调用

，它会抛出一个Uncaught TypeError

Uncaught TypeError: Cannot call method 'lookup' of undefined ember-data.js?body=1:6576
DS.RESTAdapter.DS.Adapter.extend.serializerFor ember-data.js?body=1:6576

编辑：这是路线

App.UsersNewRoute = Ember.Route.extend({
  model: function() {
    return this.store.createRecord('user');
  },

  setupController: function(controller, model) {
    controller.set('content', model);
  }
});

型号：

App.User = DS.Model.extend({
  email: DS.attr('string'),
  password: DS.attr('string'),
  passwordConfirmation: DS.attr('string')
});

商店：

App.Store = DS.Store.extend
  revision: 13
  adapter: DS.RESTAdapter.create()

似乎您的RESTAdapter没有对容器的引用。通常在ember创建适配器时设置 - 由于您手动创建实例，因此可能会丢失。尝试将App.Store声明更改为仅使用默认值：

App.Store = DS.Store.extend({})

保存模型时，EmberJS无法调用undefined方法'lookup'
