Re: Filtering foreignkey results with newforms form_for_model
Thank you James, for both the solution and the advice. I really liked forms_for_model as a crutch while I got up to speed on newforms, but like most crutches, I'm finding I may spend more time working against it. Still, a nifty thing for a simple, straightforward form.

Re: Filtering foreignkey results with newforms form_for_model
I'm still struggling with this... came up with EventFormClass.base_fields['club'].widget = widgets.Select(choices=Club.objects.filter(approved=True)) But that throws TypeError at /clubs/events/ unpack non-sequence Any ideas?

Filtering foreignkey results with newforms form_for_model
I have an "Event" model that has a foreignkey relationship with "Club", and I'm using form_for_model to create the form. This spits out all "Club" entries in a dropdown. The trick is, "Club" has a boolean field for "approved", and I want to filter according to that. So, is there some way to filter it? At the newform level. Should I get 'club.objects.filter(approved=true)' and pass that to form somehow (maybe form.club = approvedclubs)?
