Emberjs 1.0.0-RC3：不能从视图使用发送到调用控制器方法

Question

通常，我们可以从视图中访问控制器中声明的方法:this.get('controller').send('method');。在这个简单的示例中，错误如下:Uncaught TypeError: Cannot read property 'send' of undefined

jsfiddle中的完整代码。

 App = Ember.Application.create();
 App.YesController = Ember.ArrayController.extend({
   cow: function(){
       console.log('say mooooo') ;
    }  
 });
 App.YesView = Ember.View.extend({
    templateName: 'yes',
   um:  function(){    
     this.get('controller').send('cow');
   }
});

整个视图:

<script type='text/x-handlebars' data-template-name='application'>
  {{render yes}}
  {{outlet}}
</script>
<script type='text/x-handlebars' data-template-name='yes'>
   <h1> Can't use send to call controller method from view</h1>
    <button {{action 'um' target='view.content'}}> can't call controller from view</button>
  <button {{action 'cow'}}> controller action works</button>
</script>

Answer 1

据我所知，可以像这样在控制器中调用cow()方法:

App.YesView = Ember.View.extend({
  templateName: 'yes',
  um: function() {
    this.get('controller').cow();
    //this.controller.cow() // <-- this should work also
  }
})

尝试target=view而不是target=view.content，否则您将尝试在模型上调用send，这是未定义的
