Magento的：致命錯誤：調用未定義的方法Varien_Data_Collection :: addFieldToFilter（）

class Nextshopping_Shipment_Model_Mysql4_Shipment_Collection extends  Mage_Core_Model_Mysql4_Collection_Abstract 
{ 
    public function loadProductForShipment(){ 

    $coll = new Varien_Data_Collection(); 

    $shipment = Mage::getModel('shipment/shipment')->getResourceCollection(); 
    $order_item_id = array(); 
    if($shipment){ 
     foreach ($shipment as $item){ 
      $order_item_id[] = $item->getOrderItemId(); 
     } 
    } 
    $collection = Mage::getModel('sales/order_item')->getCollection(); 

    if($order_item_id){ 
     $collection = $collection ->addFieldToFilter('item_id',array('nin'=>$order_item_id)); 
    } 
    $collection->addAttributeToSelect('item_id'); 
    $collection->addAttributeToSelect('product_id'); 
    $collection->addAttributeToSelect('name'); 
    $collection->addAttributeToSelect('sku'); 
    $collection->addAttributeToSelect('qty_ordered'); 


    $collection->getSelect() 
    ->join('sales_flat_order','main_table.order_id = sales_flat_order.entity_id AND sales_flat_order.state = "complete"', 
      array('state','status as order_status','increment_id as order_increment_id')) 
      ->join('sales_flat_invoice','sales_flat_invoice.order_id = sales_flat_order.entity_id', 
        array('entity_id as invoice_id')) 
        ->join('sales_flat_order_payment','sales_flat_order_payment.entity_id = sales_flat_order.entity_id AND method != "cashondelivery"', 
          array('method')) 
          ->join('sales_flat_shipment','sales_flat_shipment.order_id = sales_flat_order.entity_id', 
            array('created_at','updated_at')); 
    if($collection){ 
     foreach ($collection as $item){ 
      $object = new Varien_Object(); 

      $object->setData($item->getData()); 

      $object->setData('qty_shipmented',0); 

      if(strtotime($item['created_at']) + 3600*24*3 < time()){ 
       $object->setData('more_than_three',$item['qty_ordered']); 
      }else{ 
       $object->setData('more_than_three',0); 
      } 

      if(strtotime($item['created_at']) +3600*24*5 < time()){ 
       $object->setData('more_than_five',$item['qty_ordered']); 
      }else{ 
       $object->setData('more_than_five',0); 
      } 

      if(strtotime($item['created_at']) +3600*24*7 < time()){ 
       $object->setData('more_than_seven',$item['qty_ordered']); 
      }else{ 
       $object->setData('more_than_seven',0); 
      } 
      $coll->addItem($object); 
     } 
    } 
    //$coll = Mage::getModel('sales/order_item')->getResourceCollection(); 
    return $coll; 
} 


protected function _prepareCollection() 
{ 
    $collection = Mage::getModel('shipment/shipment')->getCollection()->loadProductForShipment(); 
    $this->setCollection($collection); 
    return parent::_prepareCollection(); 
}

在這種方法中more_than_three是不是在一個數據庫中的自定義字段。這個系列是電網調用，但是當我點擊「搜索」程序回聲Magento的：致命錯誤：調用未定義的方法Varien_Data_Collection :: addFieldToFilter（）

Fatal error: Call to undefined method Varien_Data_Collection::addFieldToFilter() in E:\Program Files\xampp\htdocs\shopping.nextmedia.com\app\code\core\Mage\Adminhtml\Block\Widget\Grid.php on line 472

誰能告訴我該怎麼辦？

定義方法'addFieldToFilter（）''中Varien_Data_Collection'。如果它內置在框架中，請檢查您的版本是否也有一個，如果是，則可能是安裝magento失敗。 – Leri 2012-08-13 10:55:45

，如果你看看官方文檔中，你會看到類不具有這樣的方法：http://docs.magentocommerce.com/Varien/Varien_Data/Varien_Data_Collection.html

我的猜測是，你正在尋找的addFilter方法來達到同樣的;）

檢查錯誤爲什麼涉及類Varien_Data_Collection;因爲當使用Mage::getModel('sales/order_item')->getCollection();時，它應該返回Mage_Sales_Model_Resource_Order_Item_Collection類型的對象！

Varien_Data_Collection只是被Magento中的任何集合擴展的類。

另外，你可以嘗試其他的方法來創建集合 - 我不知道，如果你的版本是正確的：

// instead of 
Mage::getModel('sales/order_item')->getCollection(); 
// try something like: 
Mage::getModel('sales/order_item')->getResourceCollection(); 
// or: 
Mage::getResourceModel('sales/order_item')->getCollection(); 
// or even: 
Mage::getResourceModel('sales/order_item_collection');
