无效的方法custom_abc_model_custom :: AddFieldTofilter管理面板的Magento CE 1.9.2

Question

在我的网格文件中筛选收集，但它显示错误。

这是我的网格文件的代码

protected function _prepareCollection() {

    $custom_id = Mage::getSingleton('adminhtml/session')->getCustom()->getId();

    $collection = Mage::getModel('custom_abc/custom')
            ->addFieldToFilter('custom_id',1)
            ->getCollection();

    $adminStore = Mage_Core_Model_App::ADMIN_STORE_ID;
    $store = $this->_getStore();

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

.

这是我的型号

model / custom.php

class Custom_ABC_Model_Custom extends Mage_Core_Model_Abstract
{
  public function _construct()
  {
    parent::_construct();
    $this->_init('custom_abc/custom');
  }
}

.

model /资源/ custom.php

class Custom_ABC_Model_Resource_Custom extends Mage_Core_Model_Resource_Db_Abstract 
{
  public function _construct()
   {
       $this->_init('custom_abc/custom', 'custom_id');
   }
}

.

model /资源/自定义/ collection.php

class Custom_ABC_Model_Resource_Custom_Collection extends Mage_Core_Model_Resource_Db_Collection_Abstract{

  protected function _construct()
  {
      parent::_construct();
      $this->_init('custom_abc/custom');
  }

}

嗯，你只能应用addFieldToFilter一旦你收集，所以而不是这个：

$collection = Mage::getModel('custom_abc/custom')
            ->addFieldToFilter('custom_id',1)
            ->getCollection();

.

你应该做：

$collection = Mage::getModel('custom_abc/custom')
            ->getCollection()
            ->addFieldToFilter('custom_id',1);

.

也可能是：

$collection = Mage::getResourceModel('custom_abc/custom_collection')
            ->addFieldToFilter('custom_id',1);
