How does transaction management work in Django ORM?

In Django ORM, transaction management allows you to group multiple database operations into a single unit of work. This ensures that either all operations succeed or none at all, maintaining data integrity.

Can you explain how to use the atomic context manager?

Sure! The atomic context manager is used to wrap a block of code in a transaction. If an exception occurs within the block, all changes are rolled back. Here's a simple example:

from django.db import transaction

with transaction.atomic():
    # Your database operations here

What happens if an error occurs inside the atomic block?

If an error occurs inside the atomic block, Django will automatically roll back all changes made during that block, ensuring that your database remains consistent.

Are there any performance considerations I should be aware of?

Yes, using transactions can have performance implications. Keeping transactions short and avoiding long-running operations within an atomic block can help maintain performance.
