Even after adding the instance i am unable to populate my form. However, if
i individually populate each form both of them populate.
def updatePayment(request, id):
> sim = get_object_or_404(Sim, pk=id)
> payment = AddPaymentForm(request.POST or None, instance=Payment)
> if request.method == "POST":
> payment_form = AddPaymentForm(request.POST or None, instance=Payment)
> sim_form = UpdatePayment(request.POST, instance=sim)
> try:
> if payment_form.is_valid():
> payment_form.save()
> sim_form.save()
> messages.success(request, ("Payment has been updated"))
> else:
