Magento 创建新的数据实体 model 、 resource 和 collection 文件

一、创建model文件

class Bestbuy_PrepaidCard_Model_Used extends Mage_Core_Model_Abstract

{

 

    protected function _construct()

    {

        $this->_init('prepaidcard/used');

    }

 

}

二、创建resource文件

class Bestbuy_PrepaidCard_Model_Resource_Used extends Mage_Core_Model_Resource_Db_Abstract

{

    /**

     * Initialize resource model

     *

     */

    protected function _construct()

    {

        $this->_init('prepaidcard/used', 'id');

    }

 

}

三、创建Collection文件

class Bestbuy_PrepaidCard_Model_Resource_Used_Collection extends Mage_Core_Model_Mysql4_Collection_Abstract

{

       public function _construct()

       {

            parent::_construct();

            $this->_init('prepaidcard/used', 'id');

       }

 

 

}

最后看一下三个文件的目录层次路径：

只有这样，才能在代码中使用这样的语句来操作实体：

//giftcard
$giftcard_model = Mage::getModel('enterprise_giftcardaccount/history');
$giftcard_info = $giftcard_model->getCollection()
    ->join(array('g' => 'giftcardaccount'),'main_table.giftcardaccount_id = g.giftcardaccount_id','*')
    ->addFieldToFilter('additional_info','订单 # '.$order_info->getData('increment_id').'.')->load();
//prepaycard
$prepaycard_model = Mage::getModel('prepaidcard/used');
$prepaycard_info = $prepaycard_model->getCollection()
    ->addFieldToFilter('order_id',$this->getRequest()->getParam('order_id'))->load();

print_r($prepaycard_info->getFirstItem()->getData());
