Make Pay::Customer belongs_to :owner optional

[marckohlbrugge]

Currently, every Pay::Customer needs an owner. Is there a specific reason for this?

I would like to make it optional for the following the reason:

On my website someone can sign up through a Stripe Payment Link. Completely skipping the Rails app. I would like to listen for the checkout.session.completed webhook and create the Pay::Customer and Pay::Subscription records. At this point I do not yet have an Owner to link them to.

I will then send them an email to sign up on the website, where I'll eventually associate their Pay::Customer with their User record.

I had a reason previously, but I don't remember.

Probably can change the owner to optional in a future release.

Thanks for your reply.

FWIW, it's no longer a blocker for me as I solved the problem in different manner.

Sharing for future reference:

After someone completes the Stripe Checkout, we redirect them to our sign up process. In our case, we have an Invite record that is created in a stripe.checkout.session.completed webhook and holds the stripe_customer_id, but you could just as easily use the Stripe Checkout ?session_id=… and fetch the Stripe Customer ID through that.

Somewhere along the sign up process, once the User record has been created, we execute this code:

# Link Stripe customer & subscription if the invite contains a Stripe customer ID
if @invite.stripe_customer_id.present?
  unless Pay::Customer.exists?(processor: :stripe, processor_id: @invite.stripe_customer_id)
    @user.set_payment_processor(:stripe)
    @user.payment_processor.update!(processor_id: @invite.stripe_customer_id)
    @user.payment_processor.sync_subscriptions(status: "all")
    @user.update!(premium: true) if @user.payment_processor.subscription&.active?
  end
end

In our case the Stripe Customer already existing is optional. As some people might end up in the sign up process without paying ahead of time. If you want to require Stripe Checkout payment before the sign up process, you can just verify the Stripe Checkout Session ID and ensure the associated Stripe Customer has no matching Pay::Customer record yet.
