You won't need to call it explicitly in the methods, that is what
before_filter does. If you only need it in those two methods then
either specify that in the before filter (look at the docs for how to
do that), or don't use before filter just call it in the methods.
However if @taken is also a query on product then define a method in
product called, possibly, remaining and then in your methods just do
@remaining = @product.remaining
