如何在自定義網格中顯示任務修訂版本？

Question

我有一個自定義網格，顯示由（Owner = some-user@company.com）過濾的打開任務。

我想包括自定義網格中每個任務的最後一個修訂版本，但修訂列在設置對話框中不可用。如何從修訂歷史遍歷到個別修訂？

Answer 1

它不能用自定義網格完成，但可以用自定義代碼完成。以下是一個應用示例，它基於UserSearchComboBox中的選擇填充網格，然後在單擊事件中顯示所選任務的最新修訂。

你可以從this github repo HTML文件複製到自定義頁：

這裏是js文件：

Ext.define('CustomApp', { 
    extend: 'Rally.app.App', 
    componentCls: 'app', 

     launch: function() { 
     var context = this.getContext(); 
     var currentProject = context.getProject()._ref; 
     var panel = Ext.create('Ext.panel.Panel', { 
       layout: 'hbox', 
       itemId: 'parentPanel', 
       componentCls: 'panel', 
       items: [ 
      { 
        xtype: 'rallyusersearchcombobox', 
        fieldLabel: 'SELECT USER:', 
      project: currentProject, 
         listeners:{ 
          ready: function(combobox){ 
           this._onUserSelected(combobox.getRecord()); 
          }, 
          select: function(combobox){ 
       if (this.down('#c').html !== 'No task is selected') { 
       Ext.getCmp('c').update('No task is selected'); 
       } 
           this._onUserSelected(combobox.getRecord()); 
          }, 
          scope: this 
         } 
        }, 
      { 
        xtype: 'panel',

      width: 600, 
        itemId: 'childPanel2' 
      } 
       ],

      this.add(panel); 
     this.down('#childPanel2').add({
