渲染多个视图/控制器对 [英] Render Multiple View/Controller Pairs

问题描述

我目前正在呈现视图列表：

I am currently rendering a list of views:

  <ul>
    {{#each newsItem in controller}}
      {{view App.NewsItemView contentBinding="newsItem" class="news-item" }}
    {{/each}}
  </ul>

但我想在每个视图中注入一个NewsItemController。

But I would like to inject a NewsItemController into each view.

我试过使用 render ，但是这似乎只支持一个视图，给出异常：

I've tried using render, but this only seems to support a single view, giving the exception:

未捕获错误：Handlebars错误：无法在对象上找到属性control
。

Uncaught Error: Handlebars error: Could not find property 'control' on object .

我发现简单提及使用控制，但这似乎不包括。

I've found a brief mention of using control instead, but this no longer seems to be included.

那么，如何渲染同一个视图的多个版本，为每个版本注入一个单独的控制器？

推荐答案

{{render}} 应该固定在当前master中（如果你从Github构建它）。如果您传递模型，则应该可以多次使用它：

{{render}} should be fixed in current master (if you build it from Github). You should be able to use it multiple times if you pass a model:

<ul>
 {{#each controller}}
   {{render "newsItem" this}}
 {{/each}}
</ul>

{{control}} 但隐藏在一个标志后面（因为它仍然是实验性的）。要使用它，您需要在包含 ember.js 文件之前执行： ENV.EXPERIMENTAL_CONTROL_HELPER = true 如果你可以避免使用它，它会更好。

{{control}} is still there but hidden behind a flag (because it's still experimental). To use it you need to do : ENV.EXPERIMENTAL_CONTROL_HELPER = true before including the ember.js file. If you can avoid using it, it would be better.

但我认为最简单的方法是使用 itemController ：

However I think the simplest approach would be to use itemController:

<ul>
  {{#each controller itemController="newsItem"}}
    {{view App.NewsItemView class="news-item" }}
  {{/each}}
</ul>

我认为你可以结合它们使它更简单/ p>

I think you can combine them to make it simpler (I haven't tried it yet):

<ul>
  {{each controller itemController="newsItem" itemViewClass="App.NewsItemView"}}
</ul>
