Filtering by category in Magento 1.4

I have a custom module I made to show featured products on the homepage. I set it up to show products that are in a ‘featured’ category. It works fine in 1.3, but now in 1.4 I get the 开发者_StackOverflowfollowing error:

SQLSTATE[42S22]: Column not found: 1054 Unknown column ‘e.category_ids’ in ‘where clause’

Here’s my code:

$_productCollection = Mage::getResourceModel('reports/product_collection')
    ->addAttributeToSelect('*')
    ->addAttributeToFilter('visibility', $visibility)
    ->addAttributeToFilter('category_ids',array('finset'=>$featuredcategory))
    $_productCollection->load();

The featured category is specified from the admin.

Anyone any ideas what might be up?

Looks like the reports/product_collection Model doesn't have a category_ids attribute anymore.

$_productCollection = Mage::getResourceModel('reports/product_collection')
    ->addAttributeToSelect('*');
$_productCollection->load();
    foreach($_productCollection as $item)
    {
        var_dump(array_keys($item->getData()));
        exit;
    }

You'll need to find a different Model to grab the information you need.

Just to clarify the answer. You can get it to work by defining the featured category first:

$_featcategory = Mage::getModel('catalog/category')->load($featuredcategory); 

and then using the normal category filter:

->addCategoryFilter($_featcategory)
