如何更新成员模型中的记录

好吧,这里有一种方法来获得所选的值,让我们把它们放在应该放的地方,好吧,首先,让我们创建一个控制器,它将装饰你的响应记录,你混合了名称,你正在使用Post,所以,我将使用这个名称,这是控制器:

App.PostController = Ember.ObjectController.extend({
  selectedChanged: function() {
    //here, you have access to the selected value with this:
    // this.get('selected')

    //And also, this controller represents you object rendered on the screen,
    //so, you can change it here if you want like this:
    //this.set('whataverPropertyYouWantToChange', 'newValue');

    //then you can save this record(send the request to the server) by just doing this:
    //this.save(); this will make a request to the server
  }.observes('selected')
});

然后,为了使用该控制器,将渲染记录的循环更改为:

{{#each model itemController="post"}}
  <tr>
    <td>{{author}}</td>
    <td>{{book}}</td>
    <td>
      {{view Ember.Select
        contentBinding= 'App.names.content'
        selectionBinding='selected'}}
    </td>
  </tr>
{{/each}}

请注意,在PostController中,即使“selected”属性具有null值,也会触发观察者,您需要验证它是否为null。
