I was trying to implement stripe in Django and everything worked fine until I tried to redirect the user to a success page after the payment. Can anybody have a look at my code and tell me what I am doing wrong?

request_data = json.loads(request.body)
gig = get_object_or_404(Gig, pk=id)
stripe.api_key = settings.STRIPE_SECRET_KEY
checkout_session = stripe.checkout.Session.create(
customer_email=request_data['email'],
payment_method_types=['card'],
line_items=[
{
'price_data': {
'currency': 'eur',
'product_data': {
'name': gig.seller,

)
order = OrderDetail()
order.customer_email = request_data['email']
order.gig = gig
order.stripe_payment_intent = checkout_session.payment_intent
order.amount = int(gig.price * 100)
order.save()
# return JsonResponse({'data': checkout_session})
return JsonResponse({'sessionId': checkout_session.id})

template_name = "checkout/payment_success.html"
def get(self, request, *args, **kwargs):
session_id = request.GET.get('session_id')
if session_id is None:
return HttpResponse("failed")
stripe.api_key = settings.STRIPE_SECRET_KEY
session = stripe.checkout.Session.retrieve(session_id)
order = get_object_or_404(OrderDetail, stripe_payment_intent=session.payment_intent)

After placing an order, when I go in the 'order details' object and see the 'stripe_payment_intend' key is always empty, it doesn't get saved. What else could I try to get each different order?
CodePudding user response：
The issue is that the point when you create the Checkout Session and set the order data is disconnected from the point at which you render your success page with the PaymentSuccessView class. Just because those two pieces of code are in the same file does not mean the state will be maintained between different requests.
What you can do instead is add the order information to the Checkout Session using metadata. Then when you retrieve the Checkout Session on your success page you can read the metadata from the Checkout Session to get the associated information.
