Question

I want to change a single line of code in a single method in e.g. the class Mage_Reports_Model_Resource_Product_Collection. The easiest way seems to be to copy the entire class file to app/code/local/..., but then I have replaced the original class, not overridden a method.

How can I create a new class that inherits from e.g. Mage_Reports_Model_Resource_Product_Collection and only override one method? And still tell Magento to use my new class instead of the original.

Here’s the working code to rewrite product collection:

<global>
    <models>
        <reports_resource>
            <rewrite>
                <product_collection>Company_ModelName_Model_Resource_Product_Collection</product_collection>
            </rewrite>
        </reports_resource>
    </models>
</global>

It should work for Mage::getResourceModel('reports/product_collection') call.

Yeah and I haven’t included the <config> tag, I think you should already have even <global> one, so I felt it wasn’t necessary.
