Sencha觸摸列表/商店不會聯繫服務器

Question

我試圖把一個Sencha Touch 2前端放在一起去Rails後端（返回JSON）。但是，我發現運行以下腳本根本不會聯繫服務器。我相信這個問題有一個非常簡單的解決方案！如果我將該行添加到我的商店：autoLoad: true，則服務器已聯繫，但我在瀏覽器中看到一個永不結束的加載圖像。

非常感謝您的幫助！請讓我知道是否有任何更多的信息，你想看到。

index.js

ListDemo = new Ext.Application({ 

name: "ListDemo", 

launch: function() { 

    ListDemo.listPanel = new Ext.List({ 
     id: 'disclosurelist', 
     store: ListDemo.ListStore, 
     itemTpl: '<div class="contact">{title}</div>', 
     onItemDisclosure: function(record, btn, index) { 
      ListDemo.detailPanel.update(record.data); 
      ListDemo.Viewport.setActiveItem('detailpanel'); 
     } 
    }); 

    ListDemo.Viewport = new Ext.Panel ({ 
     fullscreen: true, 
     layout: 'card', 
     cardSwitchAnimation: 'slide', 
     items: [ListDemo.listPanel] 
    }); 

} 
}); 

data.js

Ext.regModel('Article', { 
     fields: [ 
      {name: 'title',  type: 'string'}, 
        {name: 'url',  type: 'string'} 
     ], 
     proxy: { 
      type: 'rest', 
      url : 'articles', 
      format: 'json', 
      reader: { 
       type: 'json', 
       root: 'articles', 
       record: 'entry' 
      } 
     } 
}); 

ListDemo.ListStore = new Ext.data.Store({ 
     model: 'Article' 
}) 

下面介紹一下服務器如果我訪問本地主機迴應：3000 /篇。 json：

{"articles": 
    [ 
     {"created_at":"2012-07-18T23:54:08Z","from":null,"id":1,"image":"","title":"Inquiry Seeks Accomplices of Bomber in Bulgaria","updated_at":"2012-07-21T06:13:54Z","url":"www.newyorktimes.com"}, 
     {"created_at":"2012-07-19T00:01:35Z","from":null,"id":2,"image":"","title":"Changing Harlem Celebrates Queen of Soul Food","updated_at":"2012-07-21T06:26:13Z","url":"www.newyorktimes.com/harlem"} 
    ] 
}

你的服務器腳本應該返回JSON看起來像這樣：

{ 
    "success": true, 
    "articles": [ 
     {"created_at":"2012-07-18T23:54:08Z","from":null,"id":1,"image":"","title":"Inquiry Seeks Accomplices of Bomber in Bulgaria","updated_at":"2012-07-21T06:13:54Z","url":"www.newyorktimes.com"}, 
     {"created_at":"2012-07-19T00:01:35Z","from":null,"id":2,"image":"","title":"Changing Harlem Celebrates Queen of Soul Food","updated_at":"2012-07-21T06:26:13Z","url":"www.newyorktimes.com/harlem"} 
    ] 
}
