Array, having Enumerable mixed in, has a "find" method that takes a
block and returns the first item that matches the condition in the block
(or nil if none do).
So, you should be able to do:
product = @product.find { |p| p.id == 24710290 }
I''m assuming that id is a number there... put it in quotes if not.
