When you will use it to login on the web, Relaying Party  will redirect you to your site. If you aren’t logged in on your site you’ll first have to log in, then you’ll be asked if you want to add Relaying Party to your “Trusted Roots” . Add it and next time you’ll log in it’ll be automatic - you won’t even notice your site appearance if you’ll be still logged in.
You can grant your users way to customize their OpenID by preparing form or you can automate it’s creation.
After creating user you can:
from django.contrib.auth.models import User user = User.objects.get(pk=...) # create openid for that user: user.openid_set.create(openid=user.username)
