ember-data DS.RESTAdapter导致TypeError [英] ember-data DS.RESTAdapter causes TypeError

问题描述

我正在尝试使用ember数据的Ember.js，并且定义了以下应用程序：

  window.App = Ember.Application.create（）
 
 App.store = DS.Store.create 
修订版：4 
适配器：DS.RESTAdapter。创建{bulkCommit：false} 
 
 App.Source = DS.Model.extend 
＃options 
 primaryKey：'_id'
 
＃fields 
 name：DS.attr'string'
 raw_text：DS.attr'string'
 
 App.sourcesController = Ember.ArrayProxy.create 
 content：App.store.findAll App.Source 
 
 App.ListSourcesView = Ember.View.extend 
 templateName：'app / templates / sources / list'
 sourcesBinding：'App.sourcesController'
  

该模板如下所示：

 < table> 
< thead> 
< tr> 
< th> ID< / th> 
< th> Name< / th> 
< / tr> 
< / thead> 
< tbody> 
 {{#each sources}} 
 {{view App.ShowSourceView sourceBinding =this}} 
 {{/ each}} 
< / tbody> 
< / table> 
  

当我尝试加载 App.ListSourcesView 在我的页面中，我在ember-data.js中收到错误，说：未捕获TypeError：无法读取未定义的属性map。

我无法弄清楚我做错了什么，在这种情况下，通过源码阅读并没有帮助我的困惑。有没有人经历过这个，或者可以告诉我我已经定义/没有定义不正确？

解决方案

进入此处。简而言之，ember数据期望资源列表嵌套在资源名称下，例如，如果您获得/ users /，则结果应为 {users：[]} 和不是顶级数组 [] 。

I'm trying out Ember.js with ember-data, and I have the following application defined:

window.App = Ember.Application.create()

App.store = DS.Store.create
    revision: 4
    adapter: DS.RESTAdapter.create { bulkCommit: false }

App.Source = DS.Model.extend
    # options
    primaryKey: '_id'

    # fields
    name: DS.attr 'string'
    raw_text: DS.attr 'string'

App.sourcesController = Ember.ArrayProxy.create
    content: App.store.findAll App.Source

App.ListSourcesView = Ember.View.extend
    templateName: 'app/templates/sources/list'
    sourcesBinding: 'App.sourcesController'

That template looks like this:

<table>
    <thead>
        <tr>
            <th>ID</th>
            <th>Name</th>
        </tr>
    </thead>
    <tbody>
        {{#each sources}}
        {{view App.ShowSourceView sourceBinding="this"}}
        {{/each}}
    </tbody>
</table>

When I try to load App.ListSourcesView in my page, I get an error in ember-data.js saying: Uncaught TypeError: Cannot read property 'map' of undefined.

I can't figure out what I'm doing wrong, and reading through the source isn't helping my confusion any in this case. Has anyone experienced this, or can tell me what I've defined/not defined incorrectly?

解决方案

Possibly the same thing I ran into over here. In short ember-data expects resource lists to be nested under the resource name, eg if you get /users/ then the result should be { "users": [] } and not a top-level array [].
