hi, I am not sure about this either, maybe I must not answer this :) in fact, I thought twice before posting that answer, but decided that this kind of forums are for discussion and speculation for beginners. we will learn together. anyway I'll answer, as far as I know, controllers are created and discarded for each request, so you have to initialize the variables again. this is the way it is. but, if you *really* want to do this, you can achieve a *similar* effect by using a class global variable i.e. @@myvar but this is a very bad idea, so don't do it. basically, initialize the variable in each controller method. onur -- Posted via http://www.ruby-forum.com/. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
