Получение ошибки типа при передаче модели в теге select в Django

У меня есть модель Department, в ней есть данные College и HS, когда я пытаюсь сохранить форму, я всегда получаю TypeError. Я попытался проверить форму и обнаружил, что это форма unbound, поэтому я попытался изменить тип поля department с ChoiceField на CharField и в моих шаблонах я попытался вызвать {{form.department}} и это дает мне правильные данные, но все равно выдает TypeError.

        context['department']=Department.objects.all()
        context['program']=Program.objects.all()
        context['year']=Year.objects.all()
        return context

        user.profile.program = form.cleaned_data.get('program')
