Hi Muruga,

We did some thing similar. I have extracted the coupon code generation into a gem. You may find it at https://github.com/bvsatyaram/random_password_generator This must meet any requirement you need for coupon code generation. Let me know if you don't see a requirement met :wink:

We didn't actually work on discount coupon, but on beta invites. Users can signup for beta using beta key. The following is minorly tweaked model.

class BetaInvite < ActiveRecord::Base   belongs_to :sender, :class_name => User.name   belongs_to :receiver, :class_name => User.name

  validates :beta_key, :presence => true, :uniqueness => true

  before_validation :set_beta_key, :on => :create

  # Displays the beta in a more readable format, by inserting a hyphen after every 5th character   def beta_key_for_display     str = self.beta_key     (5..24).step(6).each do |i|       str = str.insert(i, '-')     end

    return str   end

  private

  def set_beta_key     self.beta_key = generate_random_beta_key until (self.beta_key.present? && BetaInvite.find_by_beta_key(self.beta_key).nil?)   end

  def generate_random_beta_key     RandomPasswordGenerator.generate(25, :skip_lower_case => true,       :skip_symbols => true,       :skip_url_unsafe => true)   end end

Hope this helps.
