產品名稱不在Magento中的過濾器搜索的自定義網格中返回

Question

我一直試圖在我的自定義模塊的自定義網格上獲取基於SKU的產品名稱。 我成功地在網格上顯示產品名稱。

下面是下面的代碼...

<?php 
    protected function _prepareCollection() 
     { 
      $collection = Mage::getModel('questionanswer/answer')->getCollection(); 
      // $collection_join = Mage::getModel('questionanswer/answer')->getCollection() 
      //  ->join(
      //   'questionanswer/question', 
      //   '`questionanswer/question`.question_id=`main_table`.question_id' 
      //   ,array('question') 
      //  ) 
      //   ->join(
      //   'catalog/product', 
      //   '`catalog/product`.entity_id=`main_table`.product_id' 
      //   ,array('sku') 
      //  ); 

      $entityTypeId = Mage::getModel('eav/entity') 
       ->setType('catalog_product') 
       ->getTypeId(); 
      $prodNameAttrId = Mage::getModel('eav/entity_attribute') 
       ->loadByCode($entityTypeId, 'name') 
       ->getAttributeId(); 
      $collection->getSelect() 
       ->joinLeft(
      array('prod' => 'catalog_product_entity'), 
      'prod.entity_id = main_table.product_id', 
      array('sku') 
      ) 
      ->joinLeft(
      array('cpev' => 'catalog_product_entity_varchar'), 
      'cpev.entity_id=prod.entity_id AND cpev.attribute_id='.$prodNameAttrId.'', 
      array('name' => 'value') 
      )->joinLeft(
      array('que'=>'questionanswer_question'), 
      'que.question_id = main_table.question_id', 
      array('question') 
      ); 

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

     } 
    ?> 

但whernever我試圖篩選搜索的產品名稱它給我下面的錯誤..

a:5:{i:0;s:413:"SQLSTATE[42S22]: Column not found: 1054 Unknown column 'name' in 'where clause', query was: SELECT COUNT(*) FROM `questionanswer_question` AS `main_table` 
LEFT JOIN `catalog_product_entity` AS `prod` ON prod.entity_id = main_table.product_id 
LEFT JOIN `catalog_product_entity_varchar` AS `cpev` ON cpev.entity_id=prod.entity_id AND cpev.attribute_id=71 WHERE (`name` LIKE '%hp%') AND (`status` LIKE '%pending%')";i:1;s:6069:"#0 /home/vhost/_default/magento1.9.2/lib/Varien/Db/Statement/Pdo/Mysql.php(110): Zend_Db_Statement_Pdo->_execute(Array) 
#1 /home/vhost/_default/magento1.9.2/app/code/core/Zend/Db/Statement.php(291): Varien_Db_Statement_Pdo_Mysql->_execute(Array) 

我我知道它搜索列名不存在..但我想在哪裏改變...

過濾搜索工作非常細跟所有其他列...

只需添加follwing代碼

$this->addColumn('names',array(
          'header' => 'Product Name', 
          'index' => 'name', 
          'filter_index'=> 'value', 
     ));
