ruby on rails - Override the values in the method -


i have online store. there column price(using gem money). , there column "discount". , if store manager records price in column "discount", store needs display price(column "discount") think need override "price" in model. don't know how access column "price"?

class item < activerecord::base   monetize :price_cents   monetize :discount_cents     def price     if self.discount > 0       self.discount     else       ?       if call,        self.price       turns out called once again method.       self[:price]       = nil, why?     end   end end

super may work, or consider using decorators kind of stuff.
