It should be possible to have two categories with the same slug but different site_id and being able to access the category_view.
I'm running 6 eStore instances (built on top of Satchmo 0.8.1) for production use they all use the same database. I would like to have same slug names throughout my instances. However when I have two categories with the same slug and different site_id the category_view trigger a MultipleObjectsReturned error (traceback attached).
This is already fully implemented and part of the core code for product view. It's used in the view product.views.get_product
It's partially implemented in the Category model but not being used in the product.views.category_view
Find attached a patch for this ticket.
