Class variables and servers

In my local development environment I define a class variabel @@has:flock? in a modele that is included in controllers so I can reset this variable in each controller that has to change it The code in the module is module CrudActions   @@page_records=15   @@has_flock = true

   def index      if @@has_flock : paginate_conditions=['flock_id=? ',current_user.flock.id]      else paginate_conditions='' end

......and in the controller class DiswebUsersController < ApplicationController   include CrudActions   @@page_records=15 .....

That works fine locally but when I deploy the application and use an apache server it does not work anymore (@@has_flock? is false) in the method index Then the variable is not set in the module Any idees of what is happening ? I can fix it by defining a method, but I wauld like to know if that is necessery Any help is appreciate?

Hi Hans,

processes don't know each other and i.g. you can't control which
instance of your Application responds to the next request, this means:

Apache (T=0)

+ < Application (Process 0)

    @@flock = nil

+ > Fork'd Application (Process 1)

    @@flock = nil

+ > Fork'd Application (Process 2)        @@flock = nil
