So my question is how would you implement your handwritten Helpers based on the role of current user.

Would it be efficient to change the behaviour at request time? e.g. the Helper somehow figures out the role of user, and include the proper SubModule?

module ApplicationHelper
    module LoggedInHelper
        # Some functions
    end

    module GuestHelper
        # The Same functions
    end

    # If User is Guest then include GuestHelper
    # If User is LoggedIn then include LoggedInHelper

end

Is it efficient this way? is it rails way? I've got a whole bunch of function that act like this, and I don't want to wrap every single one of them in an if statement

def menu_actions
    if current_user.nil?
        # User is guest
        { "Log in" => link_to "Login", "/login" }
    else
        # User is Logged In
        { "Log out" => link_to "Logout", "/logout" }
    end
end

Thank you for your time and thoughts.
