A Caching Current User Method Call

• Tweet
• 

        A simple method that returns the current user and caches the result to reduce database hits.  This assumes you're storing user information in User and that the current user is identified by the session variable user_id.

class ApplicationController < ActionController::Base
  def current_user
    session[:user_id] ? @current_user ||= User.find(session[:user_id]) : nil
  end
end
