hi,
I have two models called Child and Sponsor. There is a model called
Sponsorship which has foreign keys to Child and Sponsor. For the
foreign key to Child, I want to limit choices to all those children
who are *not* already a foreign key to sponsorship and who are
active. This is the query I generate to get this list:
Child.objects.extra(
where=["""id not in(select child_id from web_sponsorship\
where web_sponsorship.iscurrent=True)"""]
).filter(iscurrent=True)
how do i get this into the limit_choices_to dictionary?

kg
