Rails - Apr 2013 - MyApp/lib/ directory: How to deal with it?

The Guide says about /lib directory:
     lib/  Extended modules for your application.

Somewhere I read that I could place there my custom email validator
class. But how to use it then? How to require it?

Now I do this way in  my "create" method:

def create
    require "myEmailValidator"
    @result = EmailValidator.validate(params[:email_from_form])
end

It works, but maybe is there a better way to work with it?

Isn''t it generally accepted practice to put require statements at the 
top of the file? It seem odd to me to put them inside a method as
you''ve
done here. Maybe I''m just used to treating require like import from 
other languages.

what i usually do is adding autoload_path.

in config/application.rb, i append

    config.autoload_paths += %W(#{Rails.root}/lib/validators)

then i put generic validators such as EmailValidator into lib/validators
directory

after that, all i need is

class SomeModel < ActiveRecord::Base
  validates :email, :email => true
end
