No, really, I don't, sorry. What is a 'list, list, detail'? A list is
a list, and a detail view is a detail view. If you want to show a list
of items, then you'll need to identify something that defines what
that list is - if I understand correctly, it is all models of a
certain make. In which case that is what you need to do in your second
list - select the items from the Product table that all have the same
ProductMake.
So, something like:
def show_make(request, key):
return object_list(request, Product_Model.objects.filter
(make=key))
