How to implement transaction management in Django to ensure data integrity?

In Django, transaction management is handled using the django.db.transaction module. To ensure data integrity, you can use the @transaction.atomic decorator or the transaction.atomic() context manager. They create an atomic block where all operations either succeed or are rolled back if an exception occurs.

Example of usage:

from django.db import transaction

def my_view(request):
    with transaction.atomic():
        # database operations
        obj = MyModel.objects.create(name='example')
        # if an exception occurs here, all changes will be rolled back

Or with a decorator:

from django.db import transaction

@transaction.atomic
def my_function():
    # database operations
    pass

This guarantees that the data remains in a consistent state, even if errors occur during execution.
