sessions - active record store

Question - I'm using acts_as_authenticated and would like to store sessions in ActiveRecord. I've done the correct call in config/environment.rb Still no sessions are being recorded in AR.

In looking through the code of AAA I see in authenticated_system.rb there is this call:

module AuthenticatedSystem   protected     # Returns true or false if the user is logged in.     # Preloads @current_user with the user model if they're logged in.     def logged_in?       (@current_user ||= session[:user] ? User.find_by_id(session[:user]) : :false).is_a?(User)     end

    # Accesses the current user from the session.     def current_user       @current_user if logged_in?     end

    # Store the given user in the session.     def current_user=(new_user)       session[:user] = (new_user.nil? || new_user.is_a?(Symbol)) ? nil : new_user.id       @current_user = new_user     end

Shouldn't the def current_user set the user id in an active record session ?

TIA Stuart

Thought I had restarted server before posting but did it again. Sessions now working. Sorry Stuart
