I may not be answering your question on this one, but I just an admin tool to add a user since the administrator of the system must grant the proper role to the new user. So, if am using rails_admin with the project, add the user in that tool and assign the appropriate role_id.
The code can also be setup so a user can sign-up them selves and a default role is assigned. You can also add a user with a tool such as phpmyadmin, pgadmin, sqlite-browser like http://sqlitebrowser.org/.
