javascript - Ember 数据 createRecord 不工作 : "TypeError: undefined is not a function"

Question

我正在为 Web 应用程序使用 Ember 数据，在我尝试使用“createRecord”保存一些新数据之前，一切都运行得非常顺利。

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，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 中调用一个操作来保存新记录:

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

如果我没理解错的话，这应该使用 spotId 参数向/api/training 发送一个 POST AJAX 请求。但是，似乎从未发送过 POST 请求，而是我的控制台显示:

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

有人知道这是为什么吗？这让我发疯!

从 Ember Data 的 1.0beta+ 开始，不需要定义存储。您只需定义适配器和序列化程序。

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，在您调用保存记录之前，不会进行 ajax 调用

var record = this.store.createRecord('training',{
  spotId:1
});
record.save();
