Question

我正在Magento 1.7中创建销售订单项网格。我在管理员的销售菜单下创建了一个新的子菜单。订单项目网格将显示在新行中订购的每个产品。因此，网格中可能存在多个OrderId。我在网格类中的查询是：

$collection = Mage::getResourceModel('sales/order_collection')
        ->join(
            'sales/order_item',
            '`sales/order_item`.order_id=`main_table`.entity_id',
            array(
                'skus'  => `sales/order_item`.`sku`,
                'names' => `sales/order_item`.`name`,
                'order_incharge' => `sales/order_item`.`order_incharge` ,
                'proptions' => `sales/order_item`.`product_options` ,

            ));

我没有任何GroupBy子句。当我在日志中打印此查询时，它显示为：

SELECT `main_table`.* FROM `sales_flat_order` AS `main_table` INNER JOIN `sales_flat_order_item` AS `sales/order_item` ON `sales/order_item`.order_id=`main_table`.entity_id

我的数据库中有2个订单。订单ID = 24有两个产品订单ID 25有一个产品所以上面的查询在数据库上运行时会正确显示3条记录。但是这不会显示在网格上。尝试在网格中显示时出现以下错误：

Item (Mage_Sales_Model_Order) with the same id "24" already exist";i:1;s:4274:"#0 C:\wamp\www\bakery\lib\Varien\Data\Collection\Db.php(576): Varien_Data_Collection->addItem(Object(Mage_Sales_Model_Order))

如何解决此问题，以便可以将相同的订单ID添加到集合中？

谢谢，尼特

Answer 1

您应该获得sales/order_item_collection，然后加入sales/order表格。

您的问题是您在订单上显示每件商品的订单信息。相反，您应该专门获取商品信息，并将一些订单信息与加入相混合。

根据您的需要，您甚至可能无需加入sales/order表格 - 只需sales/order_item集合即可。

感谢Marshall指出我正确的方向。这是我的解决方案，以防有人需要它

MY_MODULE_Block_Adminhtml_Order_Grid

protected function _getCollectionClass()
{
   // This is the model we are using for the grid
   // We need to work with the item collection and join the sales/order table because we wanna show one item per line
   return 'sales/order_item_collection';
}

protected function _prepareCollection()
{
    // Get the collection for the grid
    $collection = Mage::getResourceModel($this->_getCollectionClass())

    // Join the order table
    // The order item collection object already implements Mage_Core_Model_Mysql4_Collection_Abstract. 
    // That means, the join method doesn't need an array for the table and you don't need to get the table manually. 
    ->join('order', 'order_id=entity_id')

    // Get the address
    ->join(array('a' => 'sales/order_address'), 'order.entity_id = a.parent_id AND a.address_type != \'billing\'', array(
        'city'       => 'city',
        'postcode'   => 'postcode',
        'region'     => 'region',
        'country_id' => 'country_id',
        'street'     => 'street',
        'telephone'  => 'telephone'
    ))

    // Get the customer group
    ->join(array('c' => 'customer/customer_group'), 'order.customer_group_id = c.customer_group_id', array(
            'customer_group_code' => 'customer_group_code'
    ))

    // Concat customer name
    ->addExpressionFieldToSelect(
        'customer_name',
        'CONCAT({{customer_firstname}}, \' \', {{customer_lastname}})',
        array('customer_firstname' => 'order.customer_firstname', 'customer_lastname' => 'order.customer_lastname'))
    ;
