How in Ruby on Rails to rollback an add if its related ones fail?

Question

Ruby on Rails

For example, there are Subscriber and Address models and they are interconnected, that is, Subscriber is added first, and then Address is added with the Subscriber id saved.
That is something like this, in the controller:

def create
subs = Subscriber.create(...)
Address.create(subscriber_id: subs.id...)
end

Here, sometimes it can happen that the Subscriber can be added, but the Address is not (for example, the Internet is gone).
Indeed, in this case, Subscriber will be, but there will be no Address.
How to make it so that if the Address is not added, then the created Subscriber is also deleted?

Use transactions.
