Question

I have an application working in localhost and also heroku. The last time that I pushed the new version to heroku I got an error during heroku db:migrate and did heroku db:push and everything was ok.

I get the following error when executing the App.
/app/.bundle/gems/ruby/1.9.1/gems/aws-s3-0.6.2/lib/aws/s3/extensions.rb:206:in `const_missing_from_s3_library’: uninitialized constant AnswersController::Authentication (NameError)

Here is the relevant code

class AnswersController < ApplicationController
  include Authentication
  ...

Authentication is a module defined in lib:

# encoding: utf-8
require 'base64'
require 'openssl'

module Authentication
...

It is working in localhost but not in heroku.
Any help??
Thanks

Try adding the lib folder to your the config.auto_load path in application.rb

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