I have recently integrated a PayPal payment option to my project and everything is working fine for the amounts of the items in the cart except that after a payment is made the items remain in the cart and there is no payment notified to the backend.
My question is how to set a submit for the address and all the details made in the check out the template along with the paid amount to reflect in the backend.
Here is the views.py
class CheckoutView(View):
def get(self, *args, **kwargs):
try:
order = Order.objects.get(user=self.request.user, ordered=False)
form = CheckoutForm()
context = {
'form': form,
'couponform': CouponForm(),
'order': order,
'DISPLAY_COUPON_FORM': True
}
shipping_address_qs = Address.objects.filter(
user=self.request.user,
address_type='S',
default='True'
)
if shipping_address_qs.exists():
context.update(
{'default_shipping_address': shipping_address_qs[0]})
billing_address_qs = Address.objects.filter(
user=self.request.user,
address_type='B',
default='True'
)
if billing_address_qs.exists():
context.update(
{'default_billing_address': billing_address_qs[0]})
return render(self.request, "checkout.html", context)
except ObjectDoesNotExist:
messages.info(self.request, "You do not have an active order")
return redirect("core:checkout")

form = CheckoutForm(self.request.POST or None)
