Resetting Django Admin Password

This barely qualifies for a blog post, but what to do if you loaded, via loaddataa full json file from someone during testing, and don't have their user's password?

Just run the shell, and by hand reset all the passwords:

from django.contrib.auth.models import User for u in Users: u.set_password('secret')

That's why you have to keep your shell login and settings files safe !!
