无法确定magento过滤器查询中的字段名称

Question

我在使用Magento查询中的OR过滤器时遇到问题。这是我用什么：

$collection = Mage::getModel('sales/order')->getCollection() 
     ->addAttributeToSelect('*') 
     ->addAttributeToFilter(
          array(
           array('attribute'=>'status','eq'=>'pending'), 
           array('attribute'=>'created_at', 'from'=>$startDate, 'to'=>$finishDate) 
          ) 
    ); 

我想以下WHERE语句：WHERE 'status' = 'pending' OR (created_at < $startDate AND created_at > $finishDate) 但我得到以下错误消息

Fatal error: Uncaught exception 'Mage_Core_Exception' with message 'Cannot determine the field name.' in /home/content/r/o/n/ronakkaria/html/magento/app/Mage.php:563 
Stack trace:

#3 {main} thrown in /home/content/r/o/n/ronakkaria/html/magento/app/Mage.php on line 563 

我目前使用的版本1.6-2rc。

Afaik您不能使用addAttributeToFilter()到OR两个属性为sales/order模型。

使用addAttributeToSearchFilter()代替：

$startDate = '2011-01-01'; 
$finishDate = '2011-01-31'; 

var_dump(
    Mage::getModel('sales/order')->getCollection() 
    ->addAttributeToSelect('*') 
    ->addAttributeToSearchFilter(
     array(
      array(
       'attribute' => 'status', 
       'eq' => 'pending' 
      ), 
      array(
       'attribute' => 'created_at', 
       'from' => $startDate, 
       'to' => $finishDate 
      ) 
     ) 
    ) 
    ->getSelectSql(true) 
); 

这将创建一个WHERE子句：

WHERE 
    (status = 'pending') OR 
    (created_at >= '2011-01-01' AND created_at <= '2011-01-31')
