Получение ошибки с пользовательской проверкой в ​​Rails 3 ActiveModel

Я пытаюсь использовать Date Validator Gem , но у меня возникает ошибка, и я не уверен, что это потому, что модель не Active Record или нет (я видел людейпредположить, что валидация в ActiveModel, когда ее нет в ActiveRecord, немного интересна.

Я использую Ruby 1.9.2 и Rails 3.0.7.Я приложил и класс, и ошибку ниже.

Заранее спасибо за любую помощь!

Класс 

require 'ice_cube'
require 'active_support'
require 'active_support/time_with_zone'
require 'ostruct'
require 'tzinfo'
require 'active_model'
include ActiveModel::Validations
include ActiveModel::Conversion
extend ActiveModel::Naming
class Schedule
  attr_accessor :yaml, :repeat, :interval, :interval_unit, :start_time, :start_date, :end_date, :end_time, :ends, :on, :after, :monday, :tuesday, :wednesday, :thursday, :friday, :saturday, :sunday
  validates_presence_of :repeat, :start_date, :start_time, :end_date, :end_time, :ends
  validates_presence_of :interval, :interval_unit, :if => :ends_never? 
  validates_presence_of :on, :if => :ends_on_date?
  validates_numericality_of :after, :greater_than => 0, :if => :ends_after_recurrences? 
  validates :start_date, :date => { :after => Time.now }
  validates :end_date, :date => { :after => :start_date }
  validates :on, :date => { :after => :end_date } 

  def initialize(attributes = {})
  end

  def persisted?
    false
  end

  private
  def parse_schedule
    if :repeat == 0
      get_repeatable
    end

  end
  def parse_yaml
  end

  def ends_on_date?
    return :ends == "on"
  end
  def ends_never?
    return :ends == "never"
  end
  def ends_after_recurrences?
    return :ends == "after"
  end
end

Ошибка от Rails Console

Вы включили / расширили пространство имен верхнего уровня. Убедитесь, что include / extends находятся в классе. 

class Schedule

  include ActiveModel::Validations
  include ActiveModel::Conversion
  extend ActiveModel::Naming
