Hi,

I have two querysets: qs_big and qs_small with qs_small subset of
qs_big (that is, all the objects in qs_small are also objects of
qs_big). I'd like to obtain a queryset of objects which are in qs_big
but not in qs_small.
If exclude could accept a queryset as parameter I would do something
like: qs_big.exclude(qs_small). Unfortunately this is not possible.

Do you have any suggestion on how to solve the problem?

Thanks
Francesco
