How to reset user password in Graphite

gistfile1.txt

cd /opt/graphite/webapp/graphite
python ./manage.py shell
P
(InteractiveConsole)
>>> from django.contrib.auth.models import User
>>> users = User.objects.all()
>>> users
[<User: graphite>, <User: default>]
>>> users[0].set_password('password-here')
>>> users[0].save()

Wasn't working, but I followed the guide here and it worked. Key was not accessing the user from the array (queryset) but accessing the instance directly:

user = users[0]
user.set_password('123')
user.save()
