Correct. Unless you are willing to change (or replace) User there isn't a way.
One (tenuous, hackish) way to do this would be to attach an UserProfile for each User instance. Each User should have exactly one UserProfile.

I'd say that web2py has more potential than RoR, but it is a relatively new framework and... | 0 | 0 | 0 | 0 | 2010-09-05T12:11:00.000 | 7 | 0.057081 | false | 3,646,002 | 0 | 0 | 1 | 3 | I got a project in mind that makes it worth to finally take the plunge into programming.

interface. But uses it's own ORM, i.e. doesn't use SQL-Alchemy.
Web2py: Didn't research this.
Turbogears2:
Uses SQL-Alchemy by default, uses Catwalk for admin
interface, but documentation isn't as
great.
