访问Ember-CLI嵌套控制器 [英] Accessing Ember-CLI Nested Controllers

问题描述

这是我的目录结构：

controllers/
---- restaurant/
    ----items.js
---- index.js
---- restaurant.js

我的路由器声明：

this.route("restaurants",{
path: "/restaurants"
});

this.resource("restaurant", {
path: "/restaurants/:restaurant_id"
}, function() {
    this.resource("items", {
    path: "/items"
    });
});

我的商品控制器（位于restaurants / items.js）以下列开头：

My Items controller (located in restaurants/items.js) begins with the following:

export default Ember.ObjectController.extend({
    needs: ["restaurant"],
    restaurant: Ember.computed.alias('controllers.restaurant.model')

然后跟着一个动作添加

但是，我不断得到hte错误说餐厅需要添加到需求：

However, I keep getting hte error saying "restaurant" needs to be added to "needs":

ReferenceError：（生成的项目控制器）#needs不包括餐厅。要从（生成的项目控制器） ，（生成项目控制器）应该有一个需要属性，它是可以访问的控制器的数组

ReferenceError: (generated items controller)#needs does not include restaurant. To access the restaurant controller from (generated items controller), (generated items controller) should have a needs property that is an array of the controllers it has access to

这是我的设置（Ember-CLI 0.1.2 with Ember 1.7） - 当我使用壁炉适配器与firebase一起工作时，我不认为支持升级Ember（从我尝试过的）。

This is my setup (Ember-CLI 0.1.2 with Ember 1.7) - As i'm using the fireplace adapter to work with firebase, I don't think it supports upgrading Ember (from what I've tried).

DEBUG: -------------------------------
DEBUG: Ember      : 1.7.0"
DEBUG: Ember Data : 1.0.0-beta.10"
DEBUG: Handlebars : 1.3.0"
DEBUG: jQuery     : 1.11.2"
DEBUG: Fireplace  : 0.2.9"
DEBUG: -------------------------------

我已经尝试过其他Stackoverflow的答案（例如如何在Ember.js中的控制器之间进行通信），但他们似乎没有帮助。

I've tried the other Stackoverflow answers (e.g. How to communicate between controllers in Ember.js) but they don't seem to help.

有没有人知道这里发生了什么？

Does anyone know what's going on here?

推荐答案

自Ember-CLI v0.2.1 + Ember v1.10.0（可能适用于早期版本;但我还没有尝试），这是您如何做的：

As of Ember-CLI v0.2.1 + Ember v1.10.0 (could work for earlier versions; but I haven't tried), this is how you do it:

export default Ember.ObjectController.extend({
    needs: ["restaurant/items"],
    ...

要访问操作，您可以这样做：

To access actions, you'd do this:

actions: {
    myAction: function(arg1, arg2) {
      this.get('controllers.restaurant/item').send('someItemActionYouDefine', arg1, arg2);
    }
}
