problem with module loading

#5543

Hi,
I have some module called lib/test_mod.rb with code

module TestMod
  def self.included m
    return unless m < ActionController::Base
    m.helper_method :tst_helper
  end
  def tst_helper
    raise "test"
  end
end

and controller

class Nsp::UsersController < ApplicationController
  include TestMod
  
  def index
    tst_helper
  end

end

Everything looks good, but on attempt to request "index" method i see error

Routing Error







uninitialized constant Nsp::UsersController::TestMod

In Rails 3 files in lib are no longer autoloaded - you need to require them explicitly, e.g:
```
require 'test_mod'

class Nsp::UsersController < ApplicationController
  include TestMod
  
  def index
    tst_helper
  end

end
```
The reason for this is that autoload paths are eagerly loaded in production and the lib path may contain files you don't want in a production app like tasks, generators, etc.
