Magento后台的“Sales > Orders”和“Sales > Orders > Create New Order” 网格里没有“用户组”这一列。为什么我们需要这一列呢？也许你需要在网格中列出/筛选“经销商”组支付的订单。也许你能够筛选 “Sales > Orders > Create New Order” 网格通过在创建订单前的用户组来查看“经销商”客户数量。

默认情况下“Sales > Orders” 网格使用“sales_flat_order_grid”进行渲染。这个表基本上是“sales_flat_order”表的冗余子组。令人惊讶的是“sales_flat_order” 表里有“customer_group_id”列，而“sales_flat_order_grid”表中没有。所以我们第一步就是要添加“customer_group_id”列到“sales_flat_order_grid”表中。

我们通过一个类似这样的简单升级脚本来实现：

$installer->getConnection()
        ->addColumn($installer->getTable('sales/order_grid'), 'customer_group_id', array(
            'TYPE' => Varien_Db_Ddl_Table::TYPE_SMALLINT,
            'NULLABLE'  => false,
            'DEFAULT'   => '0',
            'COMMENT' => 'Customer Group'
        ));

如果这个安装/升级脚本执行成功，我们就会在“sales_flat_order_grid”表中看到“customer_group_id”列。注意，Magento会在新订单保存时自动填充“sales_flat_order_grid.customer_group_id”中的数据。

然后我们将重写Mage_Adminhtml_Block_Sales_Order_Grid和Mage_Adminhtml_Block_Sales_Order_Create_Customer_Grid。但只做些小的修改来让我们的“Customer Group”显示。

我们通过config.xml来添加合适的入口：

<global>
    <blocks>
        <adminhtml>
            <rewrite>      <sales_order_create_customer_grid>Mycompany_Myextension_Block_Adminhtml_Sales_Order_Create_Customer_Grid</sales_order_create_customer_grid>
                <sales_order_grid>Mycompany_Myextension_Block_Adminhtml_Sales_Order_Grid</sales_order_grid>
            </rewrite>
        </adminhtml>
    </blocks>
</global>

最后，添加重写模块

<?php
 
class Mycompany_Myextension_Block_Adminhtml_Sales_Order_Grid extends Mage_Adminhtml_Block_Sales_Order_Grid 
{
    protected function _prepareColumns()
    {
        $groups = Mage::getResourceModel('customer/group_collection')
            ->addFieldToFilter('customer_group_id', array('gt'=> 0))
            ->load()
            ->toOptionHash();
 
        $this->addColumn('customer_group_id', array(
            'header'    =>  Mage::helper('customer')->__('Customer Group'),
            'width'     =>  '100',
            'index'     =>  'customer_group_id',
            'type'      =>  'options',
            'options'   =>  $groups,
        ));
 
        $this->addColumnsOrder('customer_group_id', 'shipping_name');
 
        return parent::_prepareColumns();
    }
}

<?php
 
class Mycompany_Myextension_Block_Adminhtml_Sales_Order_Create_Customer_Grid extends 

Mage_Adminhtml_Block_Sales_Order_Create_Customer_Grid
{
    protected function _prepareColumns()
    {
        $groups = Mage::getResourceModel('customer/group_collection')
            ->addFieldToFilter('customer_group_id', array('gt'=> 0))
            ->load()
            ->toOptionHash();
 
        $this->addColumn('group', array(
            'header'    =>  Mage::helper('customer')->__('Group'),
            'width'     =>  '100',
            'index'     =>  'group_id',
            'type'      =>  'options',
            'options'   =>  $groups,
        ));
 
        $this->addColumnsOrder('group', 'email');
 
        return parent::_prepareColumns();
    }
}
