ruby - How to simplify my Rails money converter module? -


just out of curiosity:

is there way simplify file this:

module converter    def hourly_rate     hourly_rate_in_cents.to_d / 100 if hourly_rate_in_cents   end    def hourly_rate=(number)     self.hourly_rate_in_cents = number.to_d * 100 if number.present?   end    def price     price_in_cents.to_d / 100 if price_in_cents   end    def price=(number)     self.price_in_cents = number.to_d * 100 if number.present?   end      def amount     amount_in_cents.to_d / 100 if amount_in_cents   end    def amount=(number)     self.amount_in_cents = number.to_d * 100 if number.present?   end  end

i using these function because need store money related values integers in database, don't repitition in code.

you this

module converter    def self.def_converter(name)     define_method(name)       value_in_cents = send("#{name}_in_cents")       value_in_cents.to_d / 100 if value_in_cents.present?     end      define_method("#{name}=") |number|       send("#{name}_in_cents=", number.to_d * 100) if number.present?     end   end    def_converter(:hourly_rate)   def_converter(:price)   def_converter(:amount)  end
