Rails - Nov 2006 - class inside module is not recognized by model

I have this model:
class ThermoDetectorOrderLetter < ActiveRecord::Base
  include ElementValidation
  validates_presence_of :sales_name, :item_code, :design_type
  protected

  def validate

    radio_button_with_single_text_field_validated(errors, 
calibration_code_of_thermocouple, :calibration_code_of_thermocouple)

    order_status_validated(errors, order_status, :order_status)
.................

Other model have similar attributes:
class TubularHeaterOrderLetter < ActiveRecord::Base
  include ElementValidation
  validates_presence_of :sales_name, :item_code, :design_type
  protected

  def validate

    radio_button_with_single_text_field_validated(errors, 
calibration_code_of_thermocouple, :calibration_code_of_thermocouple)

    order_status_validated(errors, order_status, :order_status)
.................

This is ElementValidation file that is included by that two models.
module ElementValidation

  class CommonValidation < ActiveRecord::Base
    def CommonValidation.common_validation
      validates_presence_of :sales_name
    end
  end

  def order_status_validated(errors, order_status, order_status_symbol)
     .............
  end
....................

It works fine.... However I try to remove validates_presences_of: line 
from two model with this:
class ThermoDetectorOrderLetter < ActiveRecord::Base
include ElementValidation
.........
  def validate

    CommonValidation.common_validation

    radio_button_with_single_text_field_validated(errors, 
calibration_code_of_thermocouple, :calibration_code_of_thermocouple)
.........

But it said: uninitialized constant CommonValidation

Why is it not recognized? order_status_validated function that reside in 
Module ElementValidation is recognized by model.

Thank you.

You should be able to simply use:
  ElementValidation::CommonValidation.common_validation

But I think inheritance would be better suited for you here rather than 
inclusion.

Something like:

  class Element < ActiveRecod::Base
    self.abstract_class = true # prevents rails from look for
                               # table "elements" on inherited
                               # classes.
    validates_presence_of :sales_name

    def order_status_validated(errors, order_status, 
order_status_symbol)
      ...
    end
  end

  class OscillatingEtherealIonizer < Element
    #already has all default behaviors from Element class
  end
