Authlogic current_user_session and current_user
authentication, authlogic, ruby-on-rails
Solution
It doesn't need to pass it an argument since it uses a unique session ID whose functionality is built into Rails. Check out the authlogic documentation for the find method for more information on it. It's not the same thing as an Active Record class, where `find` queries the database for a specific primary key.
Problem
I have the following helper methods in the application_controller.rb for authlogic: ``` 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.record end ``` I do not understand how the current_user_session method - specifically, how UserSession.find obtains the current user's session. I also do not understand what it is doing with find, where no argument is given.
