I think, that this will be better, when in method recountUsersOnline is better to use .filter() instead of .all():

from datetime import datetime, timedelta

def recountUsersOnline(): date_now = datetime.now() delta = datetime.timedelta(seconds=-300) users = UsersOnline.objects.filter(time__lt=date_now+delta) # Deleting expired users for user in users: user.delete()
