无法使用自定义渲染器在网格中过滤或搜索产品

Question

I have a problem with filter in my module in admin grid. I also used 'order_item_id' field in my custom table and fetching product name based on '(sales/order_item)' using renderer. I also using " 'filter_condition_callback' => array($this, '_productFilter') " but it cant' work My problem is: can't Filter for columns with custom renderer not working. When i search product name in column,it returns zero records. What i wrong in My Code ?

public function _prepareColumns()
{
   $this->addColumn('entity_id', array(
      'header'    => Mage::helper('adminhtml')->__('ID'),
      'align'     =>'right',
      'width'     => '50px',
      'index'     => 'entity_id',
    ));         

    $this->addColumn('order_item_id', array(
      'header'    => Mage::helper('adminhtml')->__('Product Name'),
      'align'     =>'right',
      'index'     => 'order_item_id',
      'renderer' => 'Test_Module1_Block_Adminhtml_Renderer_Product',
      'filter_condition_callback' => array($this, '_productFilter'),
    ));
    return parent::_prepareColumns();
}
protected function _productFilter($collection, $column)
{
    if (!$value = $column->getFilter()->getValue()) {
        return $this;
    }

    $this->getCollection()->getSelect()->where(
        "order_item_id like ?
        "
    , "%$value%");


    return $this;
}

my renderer is

 class Test_Module1_Block_Adminhtml_Renderer_Product extends Mage_Adminhtml_Block_Widget_Grid_Column_Renderer_Abstract
{
    public function render(Varien_Object $row)
    {
        $order = Mage::getModel('sales/order_item')->load($row->getData('order_item_id'));

        return $order->getName();
    }
}

Answer 1

因为你渲染了id，而且你是用产品名搜索的。所以你需要改变你的productfilter功能，并根据产品名称放入table中搜索id的代码。你需要改变你的功能：

protected function _productFilter($collection, $column)
{
  if (!$value = $column->getFilter()->getValue()) {
    return $this;
}
 $orderitem = Mage::getModel('sales/order_item')->getCollection();
 $orderitem->addFieldToFilter('name',array('like'=>'%'.$value.'%'));  
   $ids =array();
  foreach($orderitem as $item){
      $ids[] = $item->getId();
 }

$this->getCollection()->addFieldToFilter("id",array("in",$ids));
return $this;
}

我对 saumik 代码及其工作做了一些更改。

protected function _productFilter($collection, $column)
    {
        if (!$value = $column->getFilter()->getValue()) {
            return $this;
        }
        $orderitem = Mage::getModel('sales/order_item')->getCollection();
        $orderitem->addFieldToFilter('name',array('like'=>'%'.$value.'%'));  
        $ids =array();
        foreach($orderitem as $item){
          $ids[] = $item->getOrderId(); //  sales_flat_order_item.order_id = sales_flat_order.entity_id
        }
        $this->getCollection()->addFieldToFilter("entity_id",array("in",$ids));
        return $this;
    }
