如何在Magento查詢中添加「order by」

Question

我爲magento安裝了一個腳本。它允許添加對訂單的評論。所以它對訂單網格顯示一個評論。

問題是它沒有按「created_at」列對評論排序。我不知道如何設置訂單。

這是代碼的一部分：

protected function _initSelect() 
{ 
    parent::_initSelect(); 

    // Join order comment 
    $this->getSelect()->joinLeft(
     array('ordercomment_table' => $this->getTable('sales/order_status_history')), 
     'main_table.entity_id = ordercomment_table.parent_id AND ordercomment_table.comment IS NOT NULL', 
     array(
      'ordercomment' => 'ordercomment_table.comment', 
     ) 
    )->group('main_table.entity_id'); 

    return $this; 
} 

感謝您的幫助。

protected function _initSelect() 
{ 
    parent::_initSelect(); 

    // Join order comment 
    $this->getSelect()->joinLeft(
     array('ordercomment_table' => $this->getTable('sales/order_status_history')), 
     'main_table.entity_id = ordercomment_table.parent_id AND ordercomment_table.comment IS NOT NULL', 
     array(
      'ordercomment' => 'ordercomment_table.comment', 
     ) 
    )->group('main_table.entity_id'); 

    //Add ORDER BY 
    $this->getSelect()->order(array('ordercomment_table.created_at DESC')); 

    return $this; 
}

在上述現有函數中替換此行。添加一個ORDER BY。

$this->getSelect()->order('ordercomment_table.created_at', 'DESC');
