In my show method for my products controller I've got a variable that track qty ( @remaining ).

Can I access this variable from another method within the same controller?


Joe,

You *can* as it is an *instance variable*, but it will only be available for that instance of the controller (i.e., a single request). If you're calling other methods during that show request, the instance variable will be available. If you want to access it from another method that responds to a different request, it won't be set. You can also use this instance variable in any views resulting from the show method.

I hope this was clear enough...

Tamara
