I am making an e-commerce website by Django and want to use Stripe Checkout Session for receiving online payments.
I followed https://stripe.com/docs/api/checkout/sessions for creating checkout sessions and https://stripe.com/docs/webhooks/build for creating the webhooks.
I could receive payments smoothly, but I want to change the 'order' to 'complete = True' right after payments are received. However, the request of view 'stripe_webhook' does not have attribute of user, so I can't call 'request.user' to get the corresponding 'order'. How could I solve this issue? Thanks so much.
models.py
class Order(models.Model):
user = models.ForeignKey(User, on_delete=models.CASCADE)
date_created = models.DateTimeField(auto_now_add=True, null = True, blank = True)
date_completed = models.DateTimeField(null = True, blank = True)
complete = models.BooleanField(default=False)
transaction_id = models.CharField(max_length=100, null=True)
def __str__(self):
return f'{self.user.username} {self.date_created}'
