When to make stripe subscription object and assign to user - Django - django

Question

Tech Stack - Django, Angular
I have been implementing stripe subscription model but stuck at some absurd scenario. I am getting Subscription not found by django. Please read the full scenario.
Firstly I am successfull in creating stripe session.
Code
session = stripe.checkout.Session.create(
metadata={'price_id':request.data.get('price_id'),'product_id':request.data.get('product_id'),'product_name':request.data.get('product_name')},
client_reference_id=request.user.id,
customer=customer.stripe_customer_id,
success_url='http://localhost:4200/success?session_id={CHECKOUT_SESSION_ID}',
cancel_url='http://localhost:4200/canceled.html',
mode='subscription',
line_items=[{
'price': request.data['price_id'],
# For metered billing, do not pass quantity
'quantity': 1,
}],
)
Webhooks Implementation:
checkout.session.completed
I am creating customer and subscription model in my db.
print(user)
customer = RecruiterUserProfile.objects.get(user = user)
print(customer)
customer.customer_id = session.customer
customer.save()
stripecustomer = Customer.objects.get(recruiter = customer, checkout_session_id = stripe_session_id)
print(stripecustomer)
stripecustomer.stripe_customer_id = stripe_customer_id
stripecustomer.save()
subscription,created = Subscriptions.objects.get_or_create(recruiter = customer,
sub_id=stripe_subscription_id,customer_id = stripecustomer,stripe_customer_id = stripe_customer_id,
payment_status=stripe_payment_status, amount = stripe_amount,
status = stripe_status, product_id = stripe_metadata['product_id'], price_id = stripe_metadata['price_id'], product_name = stripe_metadata['product_name'])
invoice.paid
Then it triggers Invoice.paid, in which I am getting the subscription model and update others values in it. But since webhooks do not wait for our calls, Sometimes, It doesn't find the subscription.
Now if I create subscription and customer in invoice.paid webhook using ger_or_create, How am I supposed to link it to the user.
Below are my models:
class Customer(models.Model):
recruiter = models.OneToOneField(RecruiterUserProfile, on_delete=models.PROTECT)
stripe_customer_id = models.CharField(max_length=80, blank=True, null=True)
checkout_session_id = models.CharField(max_length=100,blank=True,null=True)
created_at = models.DateTimeField(auto_now_add=True)
updated_at = models.DateTimeField(auto_now=True)
def __str__(self):
return f"{self.recruiter.user.email} has a stripe customer id {self.stripe_customer_id}"
def expiration():
return now() + timedelta(days=30)
class Subscriptions(models.Model):
STATUS_CHOICES =(
('utilised','Utilised'),
('accessible','Accessible'),
('notaccessible','Notaccessible')
)
recruiter = models.ForeignKey(RecruiterUserProfile, on_delete=models.PROTECT)
customer_id = models.ForeignKey(Customer, on_delete=models.PROTECT)
stripe_customer_id = models.CharField(max_length=80, blank=True, null=True)
sub_id = models.CharField(max_length=80, blank=True, null=True)
product_id = models.CharField(max_length=80, blank=True, null=True)
product_name = models.CharField(max_length=80, null=True, blank=True)
price_id = models.CharField(max_length=80, blank=True, null=True)
offer_id = models.CharField(max_length=80, blank=True, null=True)
notes = models.JSONField(default=list,blank=True)
status = models.CharField(max_length=100, default="Initial")
payment_status = models.CharField(max_length = 100, default='')
amount = models.CharField(max_length=20,blank=True, null=True)
start_date = models.DateTimeField(null=True, blank=True)
expiration_date = models.DateTimeField(
default=expiration,
verbose_name='Expirate in'
)
created_at = models.DateTimeField(auto_now_add=True)
updated_at = models.DateTimeField(auto_now=True)
client_validity = models.CharField(max_length=20,choices= STATUS_CHOICES, default='accessible')
product_job_credits = models.IntegerField(default=0)
active_job_credits = models.IntegerField(default=0)
is_cancelled = models.BooleanField(default=False)

Answer 1

I managed to solve this question by just simple workflow change. Do not call the subscription API directly. Create a stripe customer initially by yourself and store the value in your local db. So while creation subscription, you will be able to get the customer and It will be easy to link the subscription with the customer.
I can share the code if necessary.
