[Rails] Re: Maintaining non persisted data

[Cris Shupp]

I tried with statics and that did not work.  It is as if rails 
completely unloads the controller between invocations.


class TransientController < ApplicationController

  def initialize
    puts 'initialize called'
  end

  def gather
    puts 'gather'
    respond_to do |format|
      format.html # index.html.erb
    end
  end

  def show
    puts 'show '
    TransientData.firstname=(params[:firstname])
    TransientData.lastname=(params[:lastname])
    respond_to do |format|
      format.html #show.html.erb
    end
  end

end

class TransientData

  @@firstname='default1'
  @@lastname='default2'


  def self.firstname()
    @@firstname
  end

  def self.lastname()
    @@lastname
  end

  def self.lastname=(name)
    @@lastname = name
  end

  def self.firstname=(name)
    @@firstname=name
  end

end
