Having trouble with Validatable

I need to use the level option for my app, so I did 'gem install
validatable'

Next I got an error when it tried to run, so after some searching,
'require 'validatable' in environment.rb

Now it says 'Unknown key(s): level' when a view tries to render a
partial from that model..

class Person < ActiveRecord::Base
  include Validatable
  belongs_to :household

  validates_numericality_of :month_int, :level => 1
  validates_numericality_of :day_int, :level => 1
  validates_numericality_of :year_int, :level => 1
  validates_presence_of :sex, :m, :d, :y
  validates_length_of :sex, :is => 1
  validates_date :birthday, :after => Date.new(1900, 1, 1), :before =>
Proc.new { 1.day.from_now.to_date }, :before_message => 'Ensure it is
before %s', :after_message => 'Ensure it is after %s', :level => 2
  before_validation do
  # debugger
    self.month_int = self.m.to_i
    self.day_int = self.d.to_i
    self.year_int = self.y.to_i
  end
  after_validation do
    debugger
    self.birthday = Date.new(self.year_int, self.month_int,
self.day_int)
  end
end

Please help..

Hi,
      You just add include Validatable in your model after installing
validatable gem. level option will work with active record validation.
For more information refer this url - http://validatable.rubyforge.org/

I think that's what I did. I know the gem is running because I had
validates_numericality using minimum and maximum, which broke as soon
as I installed the gem. Validatable doesn't have those options. The
include is on line 2 of the model.

Can you isolate which validation is causing the issue ? just looking
at the docs for validatable, looks like it might not have a
validates_date method - you're picking up the Active Record
validates_date which of course doesn't expect a :level option
