could you please help me join the stock inventory resource to my grid.php? I would like to edit my grid in order to filter by availability "is in stock".

Tried adding this code, but without joining the resource it will not work.

    $this->addColumn('inventory_stock_availability ',
                'header' => Mage::helper('catalog')->__('Status'),
                'width' => '100px',
                'index' => 'inventory_stock_availability',
                'type' => 'options',
                'options' => Mage::getSingleton('catalog/inventory_stock_availability ')->getOptionArray(),

my grid file is just like this one https://github.com/jayelkaake/enhancedgrid/blob/master/app/code/community/TBT/Enhancedgrid/Block/Catalog/Product/Grid.php


Add below code:

$collection = Mage::getModel('catalog/product')->getCollection()
    )->joinTable('cataloginventory/stock_item', 'product_id=entity_id', array('stock_status' => 'is_in_stock'))

Add below code in function _prepareColumns()

$this->addColumn('stock_status', array(
    'header'=> 'Availability',
    'width' => '60px',
    'index' => 'stock_status',
    'type'  => 'options',
    'options' => array(
        '1' => 'In stock',
        '0' => 'Out of stock'

  • this solution does not work for me: Fatal error: Call to a member function getBackend() on a non-object in app/code/core/Mage/Eav/Model/Entity/Abstract.php on line 816 – Sam Provides Apr 5 '16 at 10:06

  • sorry where do you add the first code exactly? what line? thanks! – Sam Provides Apr 5 '16 at 10:13
  • You just need to add code: ->joinTable( 'cataloginventory/stock_item', 'product_id=entity_id', array("stock_status" => "is_in_stock") ) ->addAttributeToSelect('stock_status'); after your collection code in function _prepareCollection – Prashant Valanda Apr 5 '16 at 10:18
  • ok, that's fine now I see the column, but does it work for you when you filter it? for example by searching only "out of stock" products? for me it does not thanks again – Sam Provides Apr 5 '16 at 10:34
