如何使用 celery/cronjobs 每 5 分钟在数据库中添加一个用户

Question

How to add a user in database in every 5min using celery/cronjobs?

My code is not working:

@periodic_task(run_every=crontab( minute='5', day_of_week="*"))
def create_user():
    try
        user = registrations.objects.get(username='username',password='password')
    except User.DoesNotExist:
        user = registrations(username='username', password='password')
        user.save()

I guess you can do some thing like this.

from uuid import uuid4

@periodic_task(run_every=crontab(minute='*/5'))
def create_user():
    try:
        username = uuid4().hex # username should be unique
        user = registrations(username=username,password='pass123')
        user.save()
        # user = User.objects.create(username=username,password='pass123')  # If you are using Django auth user model, which you should. No need to call .save() on this
    except Exception, e:
        print str(e)  # Log the error
