If you want the ability — as I do — to really start with a fresh database without getting asked that superuser question, then you can just de-register the signal handler that asks that question. Check out the very bottom of the file:
django/contrib/auth/management/__init__.py
to see how the registration of the superuser function gets performed. I found that I could reverse this registration, and never get asked the question during "syncdb", if I placed this code in my "models.py":
from django.db.models import signals
from django.contrib.auth.management import create_superuser
from django.contrib.auth import models as auth_app
# Prevent interactive question about wanting a superuser created. (This
# code has to go in this otherwise empty "models" module so that it gets
# processed by the "syncdb" command during database creation.)
signals.post_syncdb.disconnect(
create_superuser,
sender=auth_app,
dispatch_uid = "django.contrib.auth.management.create_superuser")
I am not sure how to guarantee that this code gets run after the Django code that does the registration. I had thought that it would depend on whether your app or the django.contrib.auth app gets mentioned first in INSTALLED_APPS, but it seems to work for me regardless of the order I put them in. Maybe they are done alphabetically and I'm lucky that my app's name starts with a letter later than "d"? Or is Django just smart enough to do its own stuff first, then mine in case I want to muck with their settings? Let me know if you find out. :-)
