What are the best practices for database transactions in Django ORM?

When using Django ORM, it's important to manage database transactions effectively. Here are some best practices:

1. Use atomic transactions to ensure data integrity.
2. Handle exceptions properly to avoid leaving transactions open.
3. Keep transactions short to reduce locking issues.
4. Use the select_for_update() method when necessary to prevent race conditions.

Can you explain what atomic transactions are?

Atomic transactions in Django ensure that a series of database operations are executed as a single unit. If any operation fails, the entire transaction is rolled back, maintaining data integrity.

How do I implement atomic transactions in my Django views?

You can implement atomic transactions using the @transaction.atomic decorator or context manager. For example:

from django.db import transaction

@transaction.atomic
def my_view(request):
    # Your database operations here
