      errors.add(:the_bad_property, "Error Message")
    end
  end

  self.custom_validators = [] if custom_validators.nil?
  custom_validators << custom_validation_method
end

class MyClass

validates :name, presence: true
validates :email, with: format: { with: /[a-z]+/, message: "must be valid email" }
