What are your real world cases for this? If you combine several models
to make up a page, you should consider writing your own mixins that
inherit only from ContextMixin and implement get_context_data() to add
the extra information.
For example:
class OnSaleMixin(ContextMixin) :
on_sale_queryset = Products.objects.filter(on_sale=True)
def get_context_data(self, **kwargs) :
context = { 'on_sale_list': self.on_sale_queryset }
context.update(kwargs)
return super(OnSaleMixin, self).get_context_data(
**context)

class ProductList(ListView, OnSaleMixin) :
model = Products
