Stripe connect - user account and multiple vendor accounts

There seems to be a fundamental issue with dj-stripe 1.0.0 and Stripe Connect. Stripe Connect allows a single user email to be associated with different vendor accounts by adding “stripe_account=(account_id)”. However, the Customer model has:

unique_together = ("subscriber", "livemode")

Therefore, on my platform when I visit one vendor it creates an account. And then when I visit another vendor, I get an

Integrity Error: UNIQUE constraint failed: djstripe_customer.subscriber_id, djstripe_customer.livemode

I may try to remove the unique constraint but I’m not sure about the ramifications.

You can remove the constraint for now, but you might run into race conditions and such.

I suppose the real fix is to add the account to the unique_together.

@tkwon, I’m curious, did you end up dropping the relation? Are you creating a different Stripe customer for each account + django user combination in your platform? It seems like if one is doing direct charges, then that would make sense.

Update: is the main assumption in this issue incorrect?

1. The email field on Customers is never unique in Stripe—this is not specific to Connect
2. With Stripe Connect you’re usually supposed to save Customers inside connected accounts, not within the platform’s account. (This is indirectly explained in Share customers across accounts)
3. It’s my understanding that dj-stripe is not set up to sync objects from within Connect accounts and you have to just query/manage that data yourself—i.e., the platform is one account and each connected account is it’s own account, and all of them have their own unique sets of customers, charges, subscriptions, etc. and dj-stripe is only syncing the ones from the platform

If my understanding of all that is correct (especially no. 3), then is it possible you were trying to sync customers from your connected accounts into the dj-stripe customers table, and that wasn’t working because it is designed to only sync customers from the platform’s account (not the connected ones)?
