阅读官方API documentation并查看joinTable
,joinField
和joinAttribute
方法。
以下是连接与Orders集合相关的表的示例:
$this->_orders = Mage::getResourceModel('sales/order_collection')
->addAttributeToSelect('*')
->joinAttribute('billing_firstname', 'order_address/firstname', 'billing_address_id', null, 'left')
->joinAttribute('billing_lastname', 'order_address/lastname', 'billing_address_id', null, 'left')
->joinAttribute('billing_street', 'order_address/street', 'billing_address_id', null, 'left')
->joinAttribute('billing_company', 'order_address/company', 'billing_address_id', null, 'left')
->joinAttribute('billing_city', 'order_address/city', 'billing_address_id', null, 'left')
->joinAttribute('billing_region', 'order_address/region', 'billing_address_id', null, 'left')
->joinAttribute('billing_country', 'order_address/country_id', 'billing_address_id', null, 'left')
->joinAttribute('shipping_firstname', 'order_address/firstname', 'shipping_address_id', null, 'left')
->joinAttribute('shipping_lastname', 'order_address/lastname', 'shipping_address_id', null, 'left')
->joinAttribute('shipping_street', 'order_address/street', 'shipping_address_id', null, 'left')
->joinAttribute('shipping_company', 'order_address/company', 'shipping_address_id', null, 'left')
->joinAttribute('shipping_telephone', 'order_address/telephone', 'shipping_address_id', null, 'left')
->joinAttribute('shipping_fax', 'order_address/fax', 'shipping_address_id', null, 'left');
