让我们在我之前提到的其他解决方案上再试一次:-)，我已经构建了完整的扩展以向您展示如何将字段添加到网格表中。之后，您只需要一个布局更新文件即可将列添加到订单网格页面。
我将扩展名为Example_SalesGrid，但您可以根据自己的需要进行更改。
让我们从/app/etc/modules/Example_SalesGrid.xml中创建模块初始化xml 开始：
<?xml version="1.0" encoding="UTF-8"?>
<!--
Module bootstrap file
-->
<config>
<modules>
<Example_SalesGrid>
<active>true</active>
<codePool>community</codePool>
<depends>
<Mage_Sales />
</depends>
</Example_SalesGrid>
</modules>
</config>
接下来，我们在/app/code/community/Example/SalesGrid/etc/config.xml中创建模块config xml ：
<?xml version="1.0" encoding="UTF-8"?>
<config>
<modules>
<Example_SalesGrid>
<version>0.1.0</version> <!-- define version for sql upgrade -->
</Example_SalesGrid>
</modules>
<global>
<models>
<example_salesgrid>
<class>Example_SalesGrid_Model</class>
</example_salesgrid>
</models>
<blocks>
<example_salesgrid>
<class>Example_SalesGrid_Block</class>
</example_salesgrid>
</blocks>
<events>
<!-- Add observer configuration -->
<sales_order_resource_init_virtual_grid_columns>
<observers>
<example_salesgrid>
<model>example_salesgrid/observer</model>
<method>addColumnToResource</method>
</example_salesgrid>
</observers>
</sales_order_resource_init_virtual_grid_columns>
</events>
<resources>
<!-- initialize sql upgrade setup -->
<example_salesgrid_setup>
<setup>
<module>Example_SalesGrid</module>
<class>Mage_Sales_Model_Mysql4_Setup</class>
</setup>
</example_salesgrid_setup>
</resources>
</global>
<adminhtml>
<layout>
<!-- layout upgrade configuration -->
<updates>
<example_salesgrid>
<file>example/salesgrid.xml</file>
</example_salesgrid>
</updates>
</layout>
</adminhtml>
</config>
现在，我们在/app/code/community/Example/SalesGrid/sql/example_salesgrid_setup/install-0.1.0.php中创建sql升级脚本：
<?php
/**
* Setup scripts, add new column and fulfills
* its values to existing rows
*
*/
$this->startSetup();
// Add column to grid table
$this->getConnection()->addColumn(
$this->getTable('sales/order_grid'),
'customer_group_id',
'smallint(6) DEFAULT NULL'
);
// Add key to table for this field,
// it will improve the speed of searching & sorting by the field
$this->getConnection()->addKey(
$this->getTable('sales/order_grid'),
'customer_group_id',
'customer_group_id'
);
// Now you need to fullfill existing rows with data from address table
$select = $this->getConnection()->select();
$select->join(
array('order'=>$this->getTable('sales/order')),
$this->getConnection()->quoteInto(
'order.entity_id = order_grid.entity_id'
),
array('customer_group_id' => 'customer_group_id')
);
$this->getConnection()->query(
$select->crossUpdateFromSelect(
array('order_grid' => $this->getTable('sales/order_grid'))
)
);
$this->endSetup();
接下来，我们在/app/design/adminhtml/default/default/layout/example/salesgrid.xml中创建布局更新文件：
<?xml version="1.0"?>
<layout>
<!-- main layout definition that adds the column -->
<add_order_grid_column_handle>
<reference name="sales_order.grid">
<action method="addColumnAfter">
<columnId>customer_group_id</columnId>
<arguments module="sales" translate="header">
<header>Customer Group</header>
<index>customer_group_id</index>
<type>options</type>
<filter>Example_SalesGrid_Block_Widget_Grid_Column_Customer_Group</filter>
<renderer>Example_SalesGrid_Block_Widget_Grid_Column_Renderer_Customer_Group</renderer>
<width>200</width>
</arguments>
<after>grand_total</after>
</action>
</reference>
</add_order_grid_column_handle>
<!-- order grid action -->
<adminhtml_sales_order_grid>
<!-- apply the layout handle defined above -->
<update handle="add_order_grid_column_handle" />
</adminhtml_sales_order_grid>
<!-- order grid view action -->
<adminhtml_sales_order_index>
<!-- apply the layout handle defined above -->
<update handle="add_order_grid_column_handle" />
</adminhtml_sales_order_index>
</layout>
现在我们需要两个Block文件，一个用于创建过滤器选项，/ app / code / community / Example / SalesGrid / Block / Widget / Grid / Column / Customer / Group.php：
<?php
class Example_SalesGrid_Block_Widget_Grid_Column_Customer_Group extends Mage_Adminhtml_Block_Widget_Grid_Column_Filter_Select {
protected $_options = false;
protected function _getOptions(){
if(!$this->_options) {
$methods = array();
$methods[] = array(
'value' => '',
'label' => ''
);
$methods[] = array(
'value' => '0',
'label' => 'Guest'
);
$groups = Mage::getResourceModel('customer/group_collection')
->addFieldToFilter('customer_group_id', array('gt' => 0))
->load()
->toOptionArray();
$this->_options = array_merge($methods,$groups);
}
return $this->_options;
}
}
第二个将行值转换为将要显示的正确文本，/ app/code/community/Example/SalesGrid/Block/Widget/Grid/Column/Renderer/Customer/Group.php：
<?php
class Example_SalesGrid_Block_Widget_Grid_Column_Renderer_Customer_Group extends Mage_Adminhtml_Block_Widget_Grid_Column_Renderer_Abstract {
protected $_options = false;
protected function _getOptions(){
if(!$this->_options) {
$methods = array();
$methods[0] = 'Guest';
$groups = Mage::getResourceModel('customer/group_collection')
->addFieldToFilter('customer_group_id', array('gt' => 0))
->load()
->toOptionHash();
$this->_options = array_merge($methods,$groups);
}
return $this->_options;
}
public function render(Varien_Object $row){
$value = $this->_getValue($row);
$options = $this->_getOptions();
return isset($options[$value]) ? $options[$value] : $value;
}
}
仅当您从销售/订单（sales_flat_order）以外的表中创建额外的列时，才需要最后一个文件。sales / order_grid中与销售/订单中的列名匹配的所有字段都会在sales / order_grid表中自动更新。例如，如果您需要添加付款选项，则需要该观察员将字段添加到查询中，以便可以将数据复制到正确的表中。用于此目的的观察者位于/app/code/community/Example/SalesGrid/Model/Observer.php中：
<?php
/**
* Event observer model
*
*
*/
class Example_SalesGrid_Model_Observer {
public function addColumnToResource(Varien_Event_Observer $observer) {
// Only needed if you use a table other than sales/order (sales_flat_order)
//$resource = $observer->getEvent()->getResource();
//$resource->addVirtualGridColumn(
// 'payment_method',
// 'sales/order_payment',
// array('entity_id' => 'parent_id'),
// 'method'
//);
}
}
该代码基于http://www.ecomdev.org/2010/07/27/adding-order-attribute-to-orders-grid-in-magento-1-4-1.html中的示例
希望上面的示例解决您的问题。
