Here is an approach I have used. I can't tell from your question
whether this will help you or not.
class AccountEntryModelForm(ModelForm):
def __init__(self, organization=None, operation=None, *args,
**kwargs):
super(ModelForm, self).__init__(*args, **kwargs)
self.organization = organization
if self.organization:
account_entry_types =
AccountEntryType.objects.filter(organization=self.organization)
self.fields['account_entry_type'].choices = [('',
'-----------')]
self.fields['account_entry_type'].choices.extend([(aet.id,
aet.name) for aet in account_entry_types])
