diff --git a/Rails validations not running b/Rails validations not running
 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

 u = User.first
 u.name = ""
 u.save #=> nil

 The presence validation for name has not fired which is contradictory to what is stated in the above guide.
