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
does anybody know why?
do i need to store that state somewhere else?
i’m pretty confused.
