This gist is in reference to the documentation for the Rails 3.2.13 on Ruby 1.9.3 p194 (http://guides.rubyonrails.org/active_record_validations_callbacks.html#on) where it has highlighted the fact that the validations for presence can also be run using the :on => :save option. The following code will highlight it better

class User < ActiveRecord::Base
  attr_accessible :name
  validates :name, :presence => true, :on => :save
end

u = User.create
u.errors #=> nil

The audited gem is a powerful gem that helps us keeping the log of the changes that are made to the models. This gem does its job excellently but there are some issues which I have discovered when I was reading this gem..

Suppose I have a model named Customer as shown below

class Customer < ActiveRecord::Base
  attr_accessible :first_name
  audited comment_required: true
end
