Hi Chris,
Isn't it this what you are trying to do?
class DocumentForm(ModelForm):
def __init__(self, *args, **kwargs):
super(MyForm, self).__init__(*args, **kwargs)
self.fields['title'].required = False
Which works perfectly fine. You can tweak pretty much any property at
runtime like that, without replacing the field entirely.
Regards,
Boti
