Rails - Aug 2012 - Barcode Generating With Label On Canvas by using Barby gem

********UNDEFINED METHOD REGISTER ERROR IN THE FALLOWING CODE *******
Hi all,

I am trying to generate barcode(including its name as label at the
bottom of barcode image for easy understand with out scanning by barcode
scanner).

For this I am Using barby, chuncky_png, rmagick gems.
I am using the fallowing code to generate label at bottom of image by
using rmagick gem:

gem ''barby''
gem ''chunky_png''
gem ''rmagick''
 require ''rubygems''
 require ''barby''
 require ''barby/outputter/rmagick_outputter''
require ''barby/barcode/code_128''
require ''barby/outputter/prawn_outputter''
require ''pdf/writer''

module Barby
class RmBarcode < ActiveRecord::Base
    register :to_image_with_data
    def to_image_with_data
      #Make canvas  bigger
      canvas = Magick::ImageList.new
      canvas.new_image(full_width , full_height + 10)
      canvas << to_image
      canvas = canvas.flatten_images
      #Make the text
      text = Magick::Draw.new
      text.font_family = ''helvetica''
      text.pointsize = 14
      text.gravity = Magick::SouthGravity
      text.annotate(canvas , 0,0,0,0, barcode.data)
      canvas
    end
  end
end
barcode = Barby::Code128B.new(''Barcode Code Here'')
barcode.to_image_with_data.write(''barcode_2.png'')

but I am getting the fallowing error:

undefined method `register'' for #<Class:0x4d08ef0>
