How does transaction rollback work in Django?

How does transaction rollback work in Django?

In Django, a transaction rollback is used to revert the database to its previous state if an error occurs during a transaction.

Can you give me an example of how to implement it?

Sure! You can use the atomic context manager to wrap your database operations. If an exception occurs, it will automatically rollback.

What happens if I don't use transaction rollback?

If you don't use transaction rollback, any changes made during the transaction will be committed, even if an error occurs, potentially leading to data inconsistency.

Are there any performance implications of using transaction rollback?

Yes, using transactions can have performance implications, as they may lock database rows and affect concurrency, but they ensure data integrity.
