灰烬中的嵌套视图 [英] Nested Views in Ember

问题描述

我需要在Ember中使用一组嵌套的递归视图。

I've got the need for a recursive nested set of views in Ember. Basically think of it as a file structure with folders.

我想我可以用 render 做到这一点，但是那没用。在结构/显示内部视图中：

I thought I could do it with render, but that didn't work. Inside structures/show view:

{{#each child in structures}}
  {{ render 'structures/show' child }}
{{/each}}

我得到错误：

Uncaught Error: assertion failed: This view is already rendered 

我在另一个 SO问题有关使用 {{view}} 助手：

I read in another SO Question about using the {{view}} helper:

{{#each child in structure.structures}}
  {{ view App.StructuresShowView structureBinding='child'}}<br>
{{/each}}

但这无法正确呈现。

如何正确渲染具有不同对象的同一视图（和控制器？）以构建嵌套/递归视图？

How do I properly render the same view (and controller?) with a different object in order to build a nested/recursive view? Is there a better way than the object directions?

谢谢。

更新。看起来 itemControllerClass 可能是我想要的吗？

Update. Looks like itemControllerClass might be what I'm looking for? Still trying to figure it out.

推荐答案

我认为您无法调用 {{render}} 在一条路线上多次。如果您需要多次创建内容，则可能需要使用 {{control}} ，与 {{render}} ，不同之处在于 {{render}} 有一个控制器（singelton）和 {{control}}

I think you cannot call {{render}} multiple times on a single route. If you need to create something many times, you probably need to use {{control}}, which is the same as {{render}} with a difference that {{render}} has one controller (singelton) and {{control}} has a new controller every time it's called.
