How to organize a subscription in a rails project?

Question

PostgreSQL

There is a service with configured devise and cancan. You need to make a premium subscription with a number of benefits for the user. How is it usually organized to check that the subscription has expired / is active?
The only option that comes to mind is checking all users on a schedule, which, it seems to me, is not very correct.

Answer 1

I would make the field "active until", per user.
And if this field is greater than the current time - the subscription is active.
When paying, we add time.
