Ember，要重定向的组件

在我的ember应用程序中，我有一个activities路线，带有相应的路线，控制器和一些组件，模板包含：
{{carousel-activities activities=model}}
carousel-activities包含：

{{#each activities as |activity|}}
    <li>{{carousel-block activity=activity}}</li>
  {{/each}}

carousel-block包含一些HBS来显示每个活动的内容：

<div class="carousel-block">
  {{#link-to 'activity' activity class="small"}}
    <div class="full-width-image">
      <img src="{{activity.image}}" class="img img-responsive full-width" alt="{{activity.title}}">
    </div>
    <div class="text-center">
      <h1>{{activity.title}}</h1>
    </div>
  {{/link-to}}
</div>

阻止组件使用ember-gestures监视panDown，当事件发生时，阻止组件将浏览器重定向到活动详细信息页面。

如果我加载活动路线，并在其上向下滑动（引发panDown事件），我会在控制台中得到以下错误：

panDown

您不能从组件调用transitionTo（）。最好的方法是发送一个动作，它将从控制器执行转换。

export default Component.extend(RecognizerMixin, {
  recognizers: 'pan',
  panDown() {
    console.log("panDown");
    this.attrs.showDetailsAction(this.get('activity'));
  }
});

然后在你的控制器中定义动作：

export default Ember.Controller.extend({
  actions: {
    showDetails(activityData) {
      this.transitionToRoute('activity', activityData);
    }
  }
});

并将动作传递给您的元件：

{{carousel-block activity=activity showDetailsAction=(action 'showDetails')}}
