An instance variable (@...) is available in any method. Note though that since the controller is reconstructed for each request it will not survive between requests (so in the above you might want a before_filter calling set_value). To have a persistent object that survives over multiple requests (per user) then use the session. If something is always a fixed value then use a constant.
