I have two related models (Sim and Payment - A Sim can have many Payment).
On searching of Sim (by ID ) i want its detail to be populated in a form
(*which
i am able to*). But using the same form i want to save the details of
Payment model as well and want to update the Sim model as well.
I am only able to populate only Sim form using the id but the
AddPaymentForm is not populating.
def updatePayment(request, id):
> sim = get_object_or_404(Sim, pk=id)
> payment = AddPaymentForm()
> sim_form = UpdatePayment(request.POST, instance=sim)
> if request.method == "POST":
> # sim_form = UpdatePayment(request.POST, instance=payment)
> payment_form = AddPaymentForm()
> try:
> if payment_form.is_valid():
> payment_form.save()
> sim_form.save()
> messages.success(request, ("Payment has been updated"))
> else:
> messages.warning(request, ("Data in fields is incorrect,
> please try again"))
> except Exception as e:
> messages.warning(request, ("Error: {}".format(e)))
> else:
> form = UpdatePayment(instance=sim)
> payment = AddPaymentForm()
> context = {'payment': payment, 'form': form,}
> return render(request, 'payment/updatePayment.html', context)
>
