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
.
