Magento - 覆盖网格不刷新

Question

我覆盖class My_CategoryFilters_Block_Adminhtml_Catalog_Category_Tab_Product extends Mage_Adminhtml_Block_Widget_Grid并将列'可见性'添加到_prepareCollection和_prepareColumns。每当我尝试过滤时，网格都不会刷新。

我读Grid doesn't appear in custom admin module in Magento和Magento Grid Container Block not loading grid。两者都建议围绕创建一个过载的控制器。有更多的Magento经验的人可以告诉我错过了什么吗？

在此先感谢。

编辑：从代码中删除“渲染器”和“控制器”。

这是树的样子：

CategoryFilters 
├── Block 
│   └── Adminhtml 
│    └── Catalog 
│       └── Category 
│        └── Tab 
│         └── Product.php 
├── Core 
│   └── etc 
│    └── config.xml 
└── etc 

这是我的代码：

protected function _prepareCollection() 
{ 
    if ($this->getCategory()->getId()) { 
     $this->setDefaultFilter(array('in_category'=>1)); 
    } 
    $store = $this->_getStore(); 
    $collection = Mage::getModel('catalog/product')->getCollection() 
     ->addAttributeToSelect('name') 
     ->addAttributeToSelect('sku') 
     ->addAttributeToSelect('price') 
     ->addAttributeToSelect('store_id') 
     ->addStoreFilter($this->getRequest()->getParam('store')) 
     ->joinField('position', 
      'catalog/category_product', 
      'position', 
      'product_id=entity_id', 
      'category_id='.(int) $this->getRequest()->getParam('id', 0), 
      'left') 
     ->joinAttribute('visibility', 'catalog_product/visibility', 'entity_id', null, 'inner', $store->getId()); 
     ; 

    $this->setCollection($collection); 

    $this->getCollection()->addWebsiteNamesToResult(); 

    if ($this->getCategory()->getProductsReadonly()) { 
     $productIds = $this->_getSelectedProducts(); 
     if (empty($productIds)) { 
      $productIds = 0; 
     } 
     $this->getCollection()->addFieldToFilter('entity_id', array('in'=>$productIds)); 
    } 

    return parent::_prepareCollection(); 
} 


protected function _prepareColumns() 
{ 
    $this->addColumn('visibility', array(
     'header' => Mage::helper('catalog')->__('Visibility'), 
     'width' => '100', 
     'sortable' => false, 
     'index' => 'visibility', 
     'type'  => 'options', 
     'options' => Mage::getModel('catalog/product_visibility')->getOptionArray(), 
     #'renderer' => new Rogue_CategoryFilters_Block_Adminhtml_Renderer_Visibility() 
    )); 
}

这个答案有点超出了我的理解范围。我没有深入挖掘，但我认为它必须按照父母处理我的请求的方式进行。

发布更新后的代码片段。

protected function _addColumnFilterToCollection($column) 
{ 
    // Set custom filter for in category flag 
    if ($column->getId() == 'in_category') { 
     $productIds = $this->_getSelectedProducts(); 
     if (empty($productIds)) { 
      $productIds = 0; 
     } 
     if ($column->getFilter()->getValue()) { 
      $this->getCollection()->addFieldToFilter('entity_id', array('in'=>$productIds)); 
     } 
     elseif(!empty($productIds)) { 
      $this->getCollection()->addFieldToFilter('entity_id', array('nin'=>$productIds)); 
     } 
    } 
    else if ($column->getId() == 'websites') { 
     $this->getCollection()->joinField('websites', 
      'catalog/product_website', 
      'website_id', 
      'product_id=entity_id', 
      null, 
      'left'); 
     return parent::_addColumnFilterToCollection($column); 
    } 
    else { 
     parent::_addColumnFilterToCollection($column); 
    } 

    return $this; 
} 

protected function _prepareCollection() 
{ 
    $store = $this->_getStore(); 
    $collection = Mage::getModel('catalog/product')->getCollection() 
     ->addAttributeToSelect('name') 
     ->addAttributeToSelect('sku') 
     ->addAttributeToSelect('price') 
     ->addAttributeToSelect('store_id') 
     ->addStoreFilter($this->getRequest()->getParam('store')) 
     ->joinField('position', 
      'catalog/category_product', 
      'position', 
      'product_id=entity_id', 
      'category_id='.(int) $this->getRequest()->getParam('id', 0), 
      'left'); 

    if ($store->getId()) { 
     $collection->addStoreFilter($store); 
     $collection->joinAttribute('visibility', 'catalog_product/visibility', 'entity_id', null, 'inner', $store->getId()); 
    } 
    else { 
     $collection->addAttributeToSelect('visibility'); 
    } 

    $this->setCollection($collection); 

    if ($this->getCategory()->getProductsReadonly()) { 
     $productIds = $this->_getSelectedProducts(); 
     if (empty($productIds)) { 
      $productIds = 0; 
     } 
     $this->getCollection()->addFieldToFilter('entity_id', array('in'=>$productIds)); 
    } 

    parent::_prepareCollection(); 
    $this->getCollection()->addWebsiteNamesToResult(); 

    return $this; 
}
