[5.4] Related model connection after upgrade to 5.4

[RidgeA]

• Laravel Version: 5.4.0
• PHP Version: 7.0.14
• Database Driver & Version: mysql 5.7.17

Description:

Hello. I have a simple application based on Laravel to provide OAuth2 service. User's table maintained by another application and stored in another database.

So, I use 2 database connections - default connection for Laravel application (where applied migrations from laravel/passport) and secondary connection, where stored user's table.

In User model I specified custom database connection and on Laravel 5.3.x version it works properly.

After updating to 5.4 version, when I try to get acces to user's tokens (oauth/tokens endpoint) I see an error - application trying to find oauth_access_tokens table in secondary connection, while this table on primary connection.

I think the problem is that parent's model connection settings obtained by related model.

In 5.4 related models are queried based on the parent's connection, do you use Passport for this or a custom implementation?

[RidgeA]

Yep, I have just found #16103.

I use Passport.

As I understand, I should clearly setup connection for passport's models?

[themsaid]

Yes you need to set a connection for passport models if the parent model is on a non-default connection.
