Django: How to rollback (@transaction.atomic) without raising exception?

Question

I'm using Django's command to perform some tasks involving database manipulation:

class SomeCommand(BaseCommand):
    @transaction.atomic
    def handle(self, *args, **options):
        # Some stuff on the database

If an exception is thrown during execution of my program, @transaction.atomic guarantees rollback. Can I force this behavior without throwing exception? Something like:

# Doing some stuff, changing objects

if some_condition:
    # ABANDON ALL CHANGES AND RETURN

Answer 1

transaction.set_rollback can do this.

class SomeCommand(BaseCommand):     @transaction.atomic     def handle(self, *args, **options):         # Doing some stuff, changing objects         if some_condition:             # Return, rolling back transaction when atomic block exits             transaction.set_rollback(True)             return 

Quoting from the docs:

Setting the rollback flag to True forces a rollback when exiting the innermost atomic block. This may be useful to trigger a rollback without raising an exception.
