What are some examples of transactions in Django ORM?

Can you give me some examples of how to use transactions in Django ORM?

Sure! In Django ORM, you can use the transaction.atomic() context manager to manage transactions. For example:

from django.db import transaction

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

This ensures that all operations within the block are treated as a single transaction.

What happens if an error occurs inside the transaction block?

If an error occurs, the transaction will be rolled back, meaning none of the operations will be saved to the database. This helps maintain data integrity.

Can you show me a more complex example?

Absolutely! Here's a more complex example:

from django.db import transaction

@transaction.atomic()
def create_user_and_profile(username, profile_data):
    user = User.objects.create(username=username)
    Profile.objects.create(user=user, **profile_data)

In this example, both the user and profile are created in a single transaction.

Are there any best practices for using transactions?

Yes! Some best practices include keeping the transaction block as short as possible, avoiding long-running transactions, and handling exceptions properly to ensure rollbacks occur when needed.
