Double model creation after payment in django website
I am currently working on Learning management course using Django and React .I am creating payment gateway using stripe . After the payment is successfully done , the courses should be called enrolled courses and a model of it created after payment . But for some issue , double course model gets created after payment for each course purchased. I don't know the issue in code. I have attached the code of payment and model created .enter image description here
I tried to pay using stripe and get the enrolled course created of that course. But duplicate (double) enrolled course created for some reason.
