Atomic increment of a counter in django

Question

I\'m trying to atomically increment a simple counter in Django. My code looks like this:

from models import Counter
from django.db import transaction

@trans         


        

Answer 1

Keeping it simple and building on @Oduvan's answer:

counter, created = Counter.objects.get_or_create(name = name, 
                                                 defaults={'count':1})
if not created:
    counter.count = F('count') +1
    counter.save()

The advantage here is that if the object was created in the first statement, you don't have to do any further updates.
