Accessing Custom Product Attributes

[Jason Buckner]

I'm new to Satchmo and working on a project where people purchase credits that get applied to their account. My first thought was to give a product an option "credits", register for the order_success signal, and access the Products returned in the Order.

In order to access the attribute, I have to call product.productattribute_set.get(option__name='credits').value

Is this the recommended approach for this or would it be better to create a Custom Product Module that has a credits field?

Thanks,

Jason
