零追踪号码出货magento的集合

Question

我需要得到一个没有跟踪号码在magento中关联的货件的集合。

$collection = Mage::getModel('sales/order_shipment')->getCollection(); 
$collection->addAttributeTofilter('track_number', ''); //not working 

请给我一个解决方案，如果你有。

Answer 1

我需要同和管理，用下面的代码（Magento的1.9.3），以获得它：

$collection = Mage::getModel('sales/order_shipment')->getCollection() 
     ->addAttributeTofilter('track_number', array('null' => true)); 

$trackTableName = Mage::getSingleton('core/resource')->getTableName('sales/shipment_track'); 
$collection->getSelect()->joinLeft(
    array('tracking' => $trackTableName), 'main_table.order_id=tracking.order_id', 
     array() 
); 

foreach ($collection as $shipment) { 
    print_r($shipment->getData()); 
}
