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

Django 1.7

from django.db.models import F

counter, created = Counter.objects.get_or_create(name = name)
counter.count = F('count') +1
counter.save()
