Ember.js如何获取控制器的需求是嵌套的controllerName [英] Ember.js How to get controller in needs which is nested controllerName

问题描述

我想使用 this.get（'controllers.pack.query'）; 来获取
App.PackQueryController 在 App.PackController ，但失败。

我认为问题是Ember使用 pack 不 pack.query as controllerName
尝试获取控制器。
虽然我可以通过 this.controllerFor（'pack.query'），
获得控制器，但Ember说它已被弃用，请使用需要而不是

我的路由器映射喜欢下面，我定义了 needs： $

> App.Router.map（function（）{
this.resource（'pack'，function（）{
this.route（'index'，{path：'/：pack_id'}）
this.route（'query'）;
}）;
}）;

App.PackController = Ember.ObjectController.extend（{
需要：['pack.query']，
queryPack：function（）{
var packQueryCtrller = this.get（'controllers.pack.query'）;

Ember.debug（'packQueryCtrller：'+ packQueryCtrller）;
// DEBUG：packQueryCtrller：undefined

packQueryCtrller.queryPack（）; // faild packQuery未定义
}
}）;

App.PackQueryController = Ember.ArrayController.extend（{
queryPack：function（queryKey）{
//...do查询包
}
}）;


解决方案

您应该使用驼峰盒，而不是圆点符号

您的包控制器应为

  App.PackController = Ember .ObjectController.extend（{
 need：['packQuery']，
 queryPack：function（）{
 var packQueryCtrller = this.get（'controllers.packQuery'）; 
 
 Ember.debug（'packQueryCtrller：'+ packQueryCtrller）; 
 // DEBUG：packQueryCtrller：undefined 
 
 packQueryCtrller.queryPack（）; // faild packQuery未定义
} 
}）; 
  

I want to use this.get('controllers.pack.query'); to get App.PackQueryController in App.PackController, but failed.

I think the problem is Ember use pack not pack.query as controllerName when it tries to get the controller. Although I can get the controller by this.controllerFor('pack.query'), but Ember says it is deprecated, please use needs instead

My router map likes below and I've defined needs: ['pack.query'] in App.PackController

App.Router.map(function () {
    this.resource('pack', function () {
        this.route('index', {path: '/:pack_id'})
        this.route('query');
    });
});

App.PackController = Ember.ObjectController.extend({
    needs: ['pack.query'],
    queryPack: function () {
        var packQueryCtrller = this.get('controllers.pack.query');            

        Ember.debug('packQueryCtrller: ' + packQueryCtrller);
        //DEBUG: packQueryCtrller: undefined

        packQueryCtrller.queryPack(); //faild packQuery is undefined
    }
});

App.PackQueryController = Ember.ArrayController.extend({
    queryPack: function (queryKey) {
        //...do query pack
    }
});

解决方案

You should use camel case, not dot notation for this.

Your pack controller should be

 App.PackController = Ember.ObjectController.extend({
   needs: ['packQuery'],
   queryPack: function () {
     var packQueryCtrller = this.get('controllers.packQuery');            

     Ember.debug('packQueryCtrller: ' + packQueryCtrller);
     //DEBUG: packQueryCtrller: undefined

     packQueryCtrller.queryPack(); //faild packQuery is undefined
   }
});
