i'm trying create class instance variables can linked , manipulated separate class. here's code: class product attr_accessor :name, :quantity def initialize(name, quantity) @name = name @quantity = quantity end end class production def initialize(factory) @factory = factory end def create "#{@name}: #{@factory}" end end basically, i'd able use attributes instance of product class in production class. if = product.new('widget', 100), want able call a.name variable in instance of production. test have: a = product.new('widget', 100) b = production.new('building 1') puts b.create('building 1') however, it's returning following: : building 1 instead of widget: building 1 any ideas what's going wrong? i'd add, subtract, etc. quantity. i'm hoping if figure out how link name property can same quantity pretty easily. first of all, want produce product during produc...
