Rails - Mar 2010 - Authlogic and Aegis, current_user nil problem, Guest user

Hi All,

I have set up Authlogic and Aegis for role based authorization.

Each time I check if a user has permission to do something, as it
stands now I have to check ''current_user'' isn''t empty
first, like
this:

<% if current_user and current_user.may_do_something? %>

I''d like to change it so that if the user isn''t logged in, an
empty
user is created with the role of ''guest'', an like explained in
this
post:

http://www.agileweboperations.com/role-based-permissions-for-your-ruby-on-rails-application/#comment-1657

@current_user = User.find_by_id(session["user_id"]) ||
User.new(:role_name => "guest")


The problem is that I have no idea how to implement this in Authlogic,
the application controller has these two methods, can anyone help out?

def current_user_session
      return @current_user_session if defined?(@current_user_session)
        @current_user_session = UserSession.find
    end

    def current_user
      return @current_user if defined?(@current_user)
      @current_user = current_user_session &&
current_user_session.user
    end


Thanks in advance!
