I've got a big cars model. Some are assigned to one site, some to the
other. In the form I only want to show the ones appropriate to the
site, so in my view I've got:
cars = Car.objects.filter(sites__id__exact=settings.SITE_ID)
car_choices = [(i.slug, i.make) for i in cars]
FormClass = nforms.form_for_model(Club) # Create the form class
FormClass.base_fields['club_cars'].widget =
widgets.SelectMultiple(choices=car_choices)
Which - as expected - creates a multi-select box with the appropriate
cars. Problem is, when the user selects one the form validation kicks
it out, saying it is not a valid choice. If I don't use the custom
widget everything is fine, other than it showing cars it shouldn't.
What am I missing here?
