uninitialized constant Facebooker2

[Mani]

I'm attempting to create a basic app that allows you to login/logout
with facebook connect. (ruby 1.9.2p318 , Rails 3.2.3)

This is what I've done (according to the "example" section of the
youtube video here http://www.youtube.com/watch?v=H5s5yKcO6r8)

1) gem install facebooker2
seems to work fine

2. Create config/facebooker.yml with the appropriate environment.
production:
app_id: your application id
secret: your application secret
api_key: your application key

3. Create config/initializers/facebooker2.rb and place the following
line in it

Facebooker2.load_facebooker_yaml

4. Added the following line to your app/controllers/
application_controller.rb

include Facebooker2::Rails::Controller

5.Added the gem in config/environment.rb as
config.gem "facebooker2"

Now if I attempt to start the server or generate a User model ($ rails
generate model User facebook_id:string) I get a
bunch of errors.(Here FacebookerDemo is my rails application name)

For Rails 3.2, the directions are slightly different. Instead of adding the "config.gem" line to environment. rb, you should add a gem line to your Gemfile. Can you give it a try to see if that works?
