Mongoid和has_secure_password

 class User 
  include Mongoid::Document
  include ActiveModel::SecurePassword
  has_secure_password  
  validates_presence_of :password, :on => :create
  attr_accessor :email, :password, :password_confirmation

  field :username
  field :password_digest

  has_secure_password
end
