Ember数据createRecord无效:" TypeError:undefined不是函数"

我使用Ember数据作为网络应用程序,一切都运行得非常顺利,直到我尝试使用" createRecord"保存一些新数据。

这是代码的要点:

App.Store = DS.Store.extend({
  adapter: DS.RESTAdapter.create({
    namespace: 'api'
  })
});

App.Training = DS.Model.extend({
  dateTimestamp: DS.attr('number'),
  dateTime: DS.attr('string'),
  dateDay: DS.attr('number'),
  dateWeekday: DS.attr('string'),
  dateMonth: DS.attr('string'),
  teacherId: DS.attr('number'),
  teacherFirstName: DS.attr('string'),
  teacherPhoneNumber: DS.attr('string'),
  teacherAvatarCss: DS.attr('string'),
  spotName: DS.attr('string'),
  spotNamespace: DS.attr('string'),
  spotId: DS.attr('number'),
  spotHasPicture: DS.attr('string'),
  spotPictureCss: DS.attr('string'),
  spotUrl: DS.attr('string')
});

我为后端构建了一个简单的REST api,并且获取数据效果很好:

App.KalenderRoute = Em.Route.extend({
  model: function() {
    return this.store.find('training'); // This works!
  }
});

然后我尝试在我的Controller中调用一个动作来保存新记录:

App.KalenderController = Em.ArrayController.extend({
  actions: {
    addTraining: function(){
        var store = this.store;
        store.createRecord('training', {
            spotId: 5
        }); // This does not work :(
    }
  }
});

如果我已经正确理解,这应该使用spotId参数向/ api / training发送POST AJAX请求。但是,似乎从未发送过POST请求,而是我的控制台说:

TypeError: undefined is not a function 

完整堆栈跟踪:

DS.Store.Ember.Object.extend.createRecord ember-data.prod.js:1575
App.KalenderController.Em.ArrayController.extend.actions.addTraining App.js:197
Mixin.create.send ember.prod.js:15207
runRegisteredAction ember.prod.js:34269
Backburner.run ember.prod.js:7947
apply ember.prod.js:7779
run ember.prod.js:6415
handleRegisteredAction ember.prod.js:34267
(anonymous function) ember.prod.js:22582
m.event.dispatch jquery.min.js:3
r.handle

有没有人知道为什么会这样?它让我发疯了!

自从1.0beta +的Ember Data以来,不需要定义商店。您只需定义适配器和序列化器。

App.ApplicationAdapter= DS.RESTAdapter.extend({
  namespace: 'api'
});

App.Training = DS.Model.extend({
  dateTimestamp: DS.attr('number'),
  dateTime: DS.attr('string'),
  dateDay: DS.attr('number'),
  dateWeekday: DS.attr('string'),
  dateMonth: DS.attr('string'),
  teacherId: DS.attr('number'),
  teacherFirstName: DS.attr('string'),
  teacherPhoneNumber: DS.attr('string'),
  teacherAvatarCss: DS.attr('string'),
  spotName: DS.attr('string'),
  spotNamespace: DS.attr('string'),
  spotId: DS.attr('number'),
  spotHasPicture: DS.attr('string'),
  spotPictureCss: DS.attr('string'),
  spotUrl: DS.attr('string')
});

此外,在您在记录上调用保存

之前,不会进行任何ajax调用
var record = this.store.createRecord('training',{
  spotId:1
});
record.save();
