Hi, I''m creating a rails app which requires an authentication system based on an Access Control List. Basically I have a User model associated to a Role model where every user has one and only one role. The problem I''m facing right now is with the creation of new users and validation. The role has to change the validation applied to a user fields on creation (and update), for instance a user having role "employee" is forced to provide information about its phone number, while a "manager" doesn''t need to provide it. Is there a clean way to solve this without applying conditions to every validated field for every role?
