Lazy choices in Django form
Try using a ModelChoiceField instead of a simple ChoiceField. I think you will be able to achieve what you want by tweaking your models a bit. Take a look at the docs for more.
I would also add that ModelChoiceFields are lazy
by default :)
You can use the "lazy" function :)
from django.utils.functional import lazy
class CarSearchForm(forms.Form):
# lots of fields like this
bodystyle = forms.ChoiceField(choices=lazy(bodystyle_choices, tuple)())
very nice util function !
