Proviamo di nuovo con un'altra soluzione che ti ho menzionato prima :-), ho creato l'estensione completa per mostrarti come aggiungere il campo alla tabella della griglia. Successivamente è necessario solo un file di aggiornamento del layout per aggiungere la colonna alla pagina della griglia dell'ordine.
Ho chiamato l'estensione Example_SalesGrid, ma è possibile modificarlo in base alle proprie esigenze.
Iniziamo creando il modulo init xml in /app/etc/modules/Example_SalesGrid.xml :
<?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>
Quindi creiamo il nostro modulo config xml in /app/code/community/Example/SalesGrid/etc/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>
Ora creiamo lo script di aggiornamento sql in /app/code/community/Example/SalesGrid/sql/example_salesgrid_setup/install-0.1.0.php :
<?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();
Quindi creiamo il file di aggiornamento del layout in /app/design/adminhtml/default/default/layout/example/salesgrid.xml:
<?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>
Ora abbiamo bisogno di due file Block, uno per creare le opzioni di filtro, /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;
}
}
E il secondo per tradurre i valori di riga nel testo corretto che verrà visualizzato, /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;
}
}
L'ultimo file necessario è necessario solo se si crea una colonna aggiuntiva da una tabella diversa da sales / order (sales_flat_order). Tutti i campi in sales / order_grid corrispondenti al nome della colonna da sales / order vengono automaticamente aggiornati nella tabella sales / order_grid. Se è necessario aggiungere l'opzione di pagamento, ad esempio, sarà necessario che questo osservatore aggiunga il campo alla query in modo che i dati possano essere copiati nella tabella corretta. L'osservatore utilizzato per questo è in /app/code/community/Example/SalesGrid/Model/Observer.php :
<?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'
//);
}
}
Questo codice si basa sull'esempio di http://www.ecomdev.org/2010/07/27/adding-order-attribute-to-orders-grid-in-magento-1-4-1.html
Spero che l'esempio sopra risolva il tuo problema.
