Explain how to implement transaction management when working with a database using Django ORM.

In Django ORM, transaction management is implemented using the context manager transaction.atomic(). It allows grouping multiple database operations into a single transaction, which will either be fully completed or rolled back in case of an error.

Example of usage:

from django.db import transaction

try:
    with transaction.atomic():
        # Perform several database operations
        obj1.save()
        obj2.save()
        # If an exception occurs here, all changes will be rolled back
except Exception as e:
    # Error handling
    print(f"Transaction error: {e}")

You can also use the @transaction.atomic decorator for functions, so that all their code runs within a transaction.

This guarantees data integrity and prevents partial changes in case of errors.
