Do Observers in Laravel guarantee a transaction?

Question

Laravel

For example, I have a model Cards and CardTransactions
DB::transaction - Guarantees me to rollback a new transaction if an error occurs during the write-off. And I can wrap the following steps in the database in my controller (or rather in the service):
- Adding a new CardTransaction
- Decrease the balance of the card

Does the Observer transaction rollback?
For example, I will have a TransactionObserver created() which will write off the balance of the card when the CardTransaction creation event has occurred. But in the event of an error in the Observer method, I expect the saving of the new CardTransaction to be cancelled.

Thank you all in advance!

Answer 1

Does the Observer transaction rollback?

No, because there are no transactions. This could be easily verified.
