A nice way to send session data to the active recored.

application_controller.rb

class ApplicationController < ActionController::Base
  # Your existing stuff
  around_filter :you_dont_have_bloody_clue

  protected

  def you_dont_have_bloody_clue
    klasses = [ActiveRecord::Base, ActiveRecord::Base.class]
    methods = ["session", "cookies", "params", "request"]

    methods.each do |shenanigan|
      oops = instance_variable_get(:"@_#{shenanigan}") 

      klasses.each do |klass|
        klass.send(:define_method, shenanigan, proc { oops })
      end
    end

    yield

    methods.each do |shenanigan|      
      klasses.each do |klass|
        klass.send :remove_method, shenanigan
      end
    end

  end
end
