Django, i can't put function form inside generic.UpdateView - django

Question

I am making a app for one kindergarten in my city. I have kids model and payment model.
For updating kid I am using class based view generic UpdateView and for creating a payment i am using form and function view. I have not problems with payment form when I am using a different template but when I try to put it on the same template, payment form is not showing up and it's not working. Is it possible to have payment form on same template as UpdateView class ? I am using UpdateView class as profile page and I would like to have payment form on the same page. Please help. Thanks

Answer 1

class UpdateKidView(UpdateView):
model = Kids
form_class = KidsForm
second_form_class = PaymentForm
template_name = 'vrtic/update_kid.html'
success_url = reverse_lazy('vrtic:kids')
def get_context_data(self, **kwargs):
context = super(UpdateKidView, self).get_context_data(**kwargs)
context['form'] = self.form_class(instance=self.get_object())
context['second_form'] = self.second_form_class()
return context
def post(self, request, **kwargs):
kids_form = self.form_class(request.POST, request.FILES, instance=self.get_object())
if kids_form.is_valid():
kid = kids_form.save()
payment_form = self.second_form_class(request.POST)
