Rails session localization tips.

gistfile1.rb

class ApplicationController < ActionController::Base
  protect_from_forgery

  protected
  def local_session
    session[params[:controller].to_s] ||= {}
  end

  def reset_local_session
    session.delete(params[:controller].to_s)
  end
end

# This tip allows to use same session key name in different controllers.
# Also provides clear keys only for the controller name scope. 
# 
#class Page1 < ApplicationController
#  def enter
#    local_session[:params]=params 
#    redirect_to :action=>:confirm
#  end
#
#  def confirm
#    if request.post?
#      # save to file or DB
#      reset_local_session
#      redirect_to :action=>:finish
#      return
#    end
#  end
#
#  def finish
#  end
#end
#
#class Page2 < ApplicationController
#  def enter
#    local_session[:params]=params 
#    redirect_to :action=>:confirm
#  end
#
#  def confirm
#    if request.post?
#      # save to file or DB
#      reset_local_session
#      redirect_to :action=>:finish
