ruby on rails - How to create method that converts attribute's value to new value -


i have form in users input number attribute :bytesize, has integer datatype. number represents amount of bytes object @catcher.

i'd have method convert value of :bytesize megabytes. is, i'd able run @catcher.mbsize, , display number of megabytes object.

i'm pretty new rails, apologies if seems obvious.

conversion methods pretty straight-forward:

class catcher   def mbsize     self.bytesize / (1 << 20)   end end

remember attributes internally stored instance variables, attr_accessor :bytesize stored in @bytesize.
