Magento 1.4.1类别筛选器

Question

我必须显示在ajax请求上添加到特定类别的产品列表。所以当我尝试使用类别过滤方法时，它显示致命错误。使用Magento的1.4.1

Fatal error: Uncaught exception 'PDOException' with message 'SQLSTATE[42S22]: Column not found: 1054 Unknown column 'e.category_ids' in 'where clause'' in /var/www/html/wc2/lib/Zend/Db/Statement/Pdo.php:228 Stack trace:

这是我加入Ajax的文件

$_productCollection = Mage::getModel('catalog/product')->getCollection() 
->addPriceData()  
->addAttributeToSort('name', 'ASC') 
->addAttributeToFilter('category_ids',array('finset'=>'604')) 
->addCategoryFilter('category_id','604') 
->setPageSize($limit) 
->setPage($p, $limit)  
->addAttributeToSelect('*'); 



$_productCollection = Mage::getResourceModel('reports/product_collection') 
    ->addAttributeToSelect('*') 
    ->setPageSize($limit) 
    ->setPage($p, $limit)  
    ->addAttributeToFilter('category_ids',array('finset'=>'66,67')); 
foreach ($_productCollection as $_product): 
    echo $_product->getId(); 
endforeach; 

两个人都没有工作的代码。他们都显示相同的错误。请有人帮助我。 谢谢

Answer 1

$category = Mage::getModel('catalog/category')->load(604); 

$_productCollection = Mage::getModel('catalog/product')->getCollection() 
->addPriceData()  
->addAttributeToSort('name', 'ASC') 
->addCategoryFilter($category) 
->setPageSize($limit) 
->setPage($p, $limit)  
->addAttributeToSelect('*'); 

此过滤器应该工作。
