Question

very simple question here but I don’t have the answer… 😉

I just need to browse my user db by roles. I don’t know how to match the role I’m looking for with the mask created by cancan

I tried:

@users= User.role?('manager') but of course it doesn’t work.

Do you have the answer? Thanks!!

Answer 1

OK, I got it. The answer was given by Ryan B. in his excellent railscasts:

Use this scope:

  scope :with_role, lambda { |role| {:conditions => "roles_mask & #{2**ROLES.index(role.to_s)} > 0"} }

and simply apply it this way:

@admins = User.with_role('admin')
