dj-stripe way of stripe.checkout.Session.create

[Guest007]

For now, I make One-time Payments with Checkout, passing "checkout session id" to client's side and get data from webhook after payment success.
Like in Stripe's docs:

stripe_sess = stripe.checkout.Session.create(
                    api_key=stripe_key,
                    customer=customer.id,
                    payment_method_types=['card'],
                    line_items=[{
                        'name': order.oid,
                        'amount': int(final_cost['total'] * 100),
                        'currency': 'usd',
                        'quantity': 1
                    }],
                    success_url=link,
                    cancel_url=c_url,
                )

I tried to create it by dj-stripe way:

stripe_sess = Session.objects.create(
                    client_reference_id=order.oid,
                    customer=customer,
                    payment_method_types=['card'],
                    display_items=[{
                        'name': order.oid,
                        'amount': int(final_cost['total'] * 100),
                        'currency': 'usd',
                        'quantity': 1
                    }],
                    success_url=link,
                    cancel_url=c_url,
                )

but got error due to empty (not unique) id field (on second session - first session creates with empty id)
How can I create Session with non-empty (autofilled?) id?

Hi, you should almost never directly call djstripe object.create (or objects.get_or_create), because those won't trigger object creation in stripe.

A few classes do have their own create classmethods eg Plan.create - note that that's not Plan.objects.create, but Session doesn't have that yet.

Currently your best bet is your existing first example, and the using Session.sync_from_stripe_data(stripe_sess) to sync that to the database.

@Guest007 in your code..

stripe_sess = stripe.checkout.Session.create(
                    api_key=stripe_key,
                    customer=customer.id,
                    ...
                )

That customer.id.. did you create a DJ-stripe Customer object?

If so, why? Wouldn't be better to use request.user? Just in case the payment fails or gets cancelled.

                    api_key=stripe_key,
                    customer=customer.id,
                    ...
                )

That customer.id.. did you create a DJ-stripe Customer object?

Yes. I do customer, created = Customer.get_or_create(subscriber=user) before shown code

that's what i mean.. if the payment fails, your customer object would be invalid.

Why? If now Customer for this User - it will be created. Once. In next try we got existed Customer, associated with giver User.

See https://github.com/dj-stripe/dj-stripe/issues/1228; docs updates are coming to make this more clear.
