Question about state during subsequent calls of an action

Hi!

i'm developing a rails application for a university assignment. i'll spare you the details as i think my question is much more general.

i have a model, called TreasureHunt, which contains a class variable, @@idno, and a reader class method, TreasureHunt.idno. in the initializer, i increment the @@idno variable, to keep track of the number of objects instantiated.

then i have a controller, treasurehunt_controller, with an action, called load, which does some things (loads a treasurehunt and blah blah blah). in the load method, i create a treasurehunt object, thus supposedly incrementing the @@idno variable.

the problem is i'm not (incrementing the variable).

when i debug the app (using a flash that gets displayed in my layout), the @@idno variable is always 1, even after subsequent calls of the load action.

does anybody know why?

do i need to store that state somewhere else? i'm pretty confused.

thanks asy

in development mode classes are reloaded between requests, so on the second request you get a brand new TreasureHunt class, with a brand new @@idno variable
