There is no relationship between the Order and the Seller, so you can't
filter the Order's based on a specific Seller. You probably want to add a
FK from Order to Seller.

I'm a bit confused. Are you trying to filter based on kwarg arguments
captured through your urls.py, or via GET/POST parameters provided by a
form, or just trying to limit the scope of available objects that a
specific user can see?

Everything you've shown here is a model (not an app). Filtering is
generally performed either in the views, and/or in the model managers. Can
you provide the views and possibly mixins?

If you have existing filters that aren't working, please post up that code
along with any trace backs.
