Do transactions work in a loop in Django?

Question

Django

There is a function processing the request. The application structure requires that writing to the database is carried out in a loop in a separate function:

def responseFunction(request):
    for el in request.POST['elements']:
        #...
        saveToDb(el)

def saveToDb(el):
    #...
    enrty.save()
    return HttpResponse()

Whether probably in that case to carry out all records in a cycle by transaction?
There is this line in settings.MIDDLEWARE_CLASSES: 'django.middleware.transaction.TransactionMiddleware', but the transaction does not work - if an error occurs in one of the iterations, the actions of the previous ones are not rolled back

Answer 1

Specify 'ATOMIC_REQUESTS': True in DBMS connection settings in jang and all your requests will turn into transactions
