如何在Magento的低库存集合中只获得启用的产品

Question

/** @var $collection Mage_Reports_Model_Resource_Product_Lowstock_Collection  */
        $collection = Mage::getResourceModel('reports/product_lowstock_collection')
            ->addAttributeToSelect('*')
            ->setStoreId($storeId)
            ->filterByIsQtyProductTypes()
            ->joinInventoryItem('qty')
            ->joinInventoryItem('low_stock_date')
            ->useManageStockFilter($storeId)
            ->useNotifyStockQtyFilter($storeId)
            ->setOrder('qty', Varien_Data_Collection::SORT_ORDER_ASC);

->addAttributeToFiler('status', array('eq' => Mage_Catalog_Model_Product_Status::STATUS_ENABLED))

有人知道怎么做吗？

Answer 1

您将需要加入保存每个产品状态值的catalog_product_entity_int表，为了方便起见，请确保status属性的attribute_id，在我的示例中是96。您可以从管理面板Manage Attributes或EAV_Attribute表中检查它。

下面是要应用的内部联接：

$collection = Mage::getResourceModel('reports/product_lowstock_collection')
            ->addAttributeToSelect('*')
            ->setStoreId($storeId)
            ->filterByIsQtyProductTypes()
            ->joinInventoryItem('qty')
            ->joinInventoryItem('low_stock_date')
            ->useManageStockFilter($storeId)
            ->useNotifyStockQtyFilter($storeId)
            ->setOrder('qty', 'asc')
                 ->getSelect()
                 ->join(Mage::getConfig()->getTablePrefix().'catalog_product_entity_int', 'lowstock_inventory_item.product_id ='.Mage::getConfig()->getTablePrefix().'catalog_product_entity_int.entity_id',array('value'))
                 ->where(Mage::getConfig()->getTablePrefix().'catalog_product_entity_int.value=1 AND '.Mage::getConfig()->getTablePrefix().'catalog_product_entity_int.attribute_id=96');

这是生成的SQL查询：

SELECT `e`.*, `lowstock_inventory_item`.`qty`, `lowstock_inventory_item`.`low_stock_date`, `catalog_product_entity_int`.`value` FROM `catalog_product_entity` AS `e`
 INNER JOIN `cataloginventory_stock_item` AS `lowstock_inventory_item` ON e.entity_id = lowstock_inventory_item.product_id
 INNER JOIN `catalog_product_entity_int` ON lowstock_inventory_item.product_id =catalog_product_entity_int.entity_id WHERE (((`e`.`type_id` = 'simple') OR (`e`.`type_id` = 'virtual') OR (`e`.`type_id` = 'giftcard'))) AND (IF(lowstock_inventory_item.use_config_manage_stock = 1, 1, lowstock_inventory_item.manage_stock) = 1) AND (qty < IF(lowstock_inventory_item.use_config_notify_stock_qty = 1, 1, lowstock_inventory_item.notify_stock_qty)) AND (catalog_product_entity_int.value=1 AND catalog_product_entity_int.attribute_id=96)
