class BigDecimal
  class << self
    def new_with_commas(*args)
      if args.first.is_a?(String) && args.first=~/,/
        args.first.gsub!(',','')
      end
      new_without_commas(*args)
    end
    alias_method_chain :new, :commas

model.rb

class Sample < ActiveRecord::Base
  
  #Create an arrayt that contains all BigDecimal fields
  FLOATING_ATTRIBUTES = %w(price quantity tva_rate)

  #Overcharge '=' method and sub all ',' with '.'
  FLOATING_ATTRIBUTES.each do |attr|
    define_method "#{attr}=" do |p|
