What methods can be used to implement transaction processing via endpoint in Django?

In Django, to handle transactions in an endpoint, several approaches can be used:

1. Decorator @transaction.atomic — wraps the view function, ensuring atomicity of all database operations inside it.

from django.db import transaction
from django.http import JsonResponse

@transaction.atomic
def my_view(request):
    # database operations
    return JsonResponse({'status': 'ok'})

2. Context manager transaction.atomic() — explicitly limits the scope of the transaction inside a function.

from django.db import transaction

def my_view(request):
    with transaction.atomic():
        # database operations
    return JsonResponse({'status': 'ok'})

3. Using middleware or mixins — for more global control of transactions at the class-based view level.

4. Exception handling — to ensure that in case of errors, the transaction is rolled back automatically.

Thus, data integrity can be guaranteed during complex operations in an endpoint.
