Hi Tom, What do you mean callable? I tried changing desig_group = forms.ChoiceField(choices=choice_desig()) to desig_group = forms.ChoiceField(choices=choice_desig)
It gave error 'function' object is not iterable. But I want to know if the following would work. desig = forms.ModelChoiceField(queryset=Group.objects.all()) But how do I change my view and template for it. Can you please correct my view and template.
