How do I use transaction.atomic in Django?

You can use transaction.atomic as a context manager to wrap your database operations. It ensures that all operations within the block are executed as a single transaction.

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

Sure! Here's a simple example:

from django.db import transaction

with transaction.atomic():
    # Your database operations here
    obj1.save()
    obj2.save()

This will ensure that both saves are treated as a single transaction.

What happens if one of the operations fails?

If any operation within the transaction.atomic block fails, all changes made in that block will be rolled back, ensuring data integrity.

Are there any performance considerations I should be aware of?

Yes, using transactions can lock database rows, which may lead to performance issues if not managed properly. It's best to keep the block as short as possible.
