Magento Grid - 将平台连接到EAV后,分拣和过滤工作不正确

Question

我有2个自定义收藏.平面数据的常用集合.我需要加入他们给客户选择.它适用于innerJoin,但对连接字段的过滤和排序不起作用.我怎么解决这个问题？

_prepareCollection()示例

$collection = Mage::getResourceModel('customer/customer_collection')
    ->addNameToSelect()
    ->addAttributeToSelect('email');

$collection
    ->getSelect()
    ->joinInner(array('my_table' => $collection->getTable('my/table')), 'e.entity_id = my_table.customer_id', array('custom_field' => my_table.custom_field))
    ->joinInner(array('my_table1' => $collection->getTable('my/table1')), 'my_table1.other_id = my_table.id', array('custom_field1' => my_table1.custom_field));

$this->setCollection($collection);
return parent::_prepareCollection();

因此,排序和过滤不适用于custom_field和custom_field1

添加列调用:

$this->addColumn('custom_field',
        array(
            'header'=>$this->__('Shopping club name'),
            'index'=>'custom_field',
            'filter_index'=>'my_table.custom_field',
    ));

过滤时我得到了致命的错误:

Call to a member function getBackend() on a non-object

排序不起作用,没有显示错误

如果您将平面连接到平面表,'filter_index'可以正常工作.但这里平坦加入了EAV.

这实际上并不太难!

当我这样做时,我将last_login添加到客户网格中.

第一步,您已经完成但我在这里包括完整性,是将列添加到初始select语句:

/**
 * set collection object
 *
 * @param Mage_Customer_Model_Resource_Customer_Collection $collection
 */
public function setCollection($collection)
{
    //Group by email since multiple customer_ids can exist in the log/customer.
    $collection->groupByEmail();

    //join the last_login field here.
    $collection->getSelect()->joinLeft(array('c_log' => $collection->getTable('log/customer')), 'c_log.customer_id=e.entity_id', array('last_login' => 'login_at'));

    parent::setCollection($collection);
}

接下来,我们将列添加到网格中.请注意,我们正在定义两个回调.'filter_condition_callback'是Magento的股票.奇怪的是,没有回调索引(据我所知)对此进行排序.我们需要添加一个排序回调,否则我们无法对新列进行排序.

    $this->addColumnAfter('last_login', array(
         'header'                    => Mage::helper('customer')->__('Last Login'),
         'type'                      => 'datetime',
         'align'                     => 'center',
         'index'                     => 'last_login',
         'filter_index'              => '`c_log`.`login_at`',
         'gmtoffset'                 => true,
         //Stock Magento Callback - Notice the callback key has been assigned.
         'filter_condition_callback' => 'filter_last_login',
         //Custom Callback Index
         'order_callback'            => 'sort_last_login'
    ), 'customer_since');

接下来,我们添加将处理过滤和排序的回调函数:

if (!function_exists('filter_last_login')) {
    /**
     * @param Mage_Customer_Model_Resource_Customer_Collection $collection
     * @param Mage_Adminhtml_Block_Widget_Grid_Column          $column
     */
    function filter_last_login($collection, $column)
    {
        if (!$column->getFilter()->getCondition()) {
            return;
        }

        $condition = $collection->getConnection()
            ->prepareSqlCondition('c_log.login_at', $column->getFilter()->getCondition());
        $collection->getSelect()->where($condition);
    }
}

if (!function_exists('sort_last_login')) {
    /**
     * @param Mage_Customer_Model_Resource_Customer_Collection $collection
     * @param Mage_Adminhtml_Block_Widget_Grid_Column          $column
     */
    function sort_last_login($collection, $column)
    {
        $collection->getSelect()->order($column->getIndex() . ' ' . strtoupper($column->getDir()));
    }
}

最后,由于order_callback不是真正的索引,我们需要在定义时调用此回调而不是默认的排序机制.这就是我完成它的方式:

/**
 * Sets sorting order by some column
 *
 * @param Mage_Adminhtml_Block_Widget_Grid_Column $column
 *
 * @return Mage_Adminhtml_Block_Widget_Grid
 */
protected function _setCollectionOrder($column)
{
    if ($column->getOrderCallback()) {
        call_user_func($column->getOrderCallback(), $this->getCollection(), $column);

        return $this;
    }

    return parent::_setCollectionOrder($column);
}

希望这有助于某人.

你能展示一个addColumn()调用,它将你的属性添加到网格中吗？

应该是这样的:

$this->addColumn('custom_field', array(
    ...
    'filter_index' => 'my_table.custom_field',
    ...
));

您可能为"filter_index"键设置了别名值.
