Rails: Omniauth - "The parameter app_id is required"

I'm following this railscast tutorial to set up omniauth for facebook authentication on my rails project: http://railscasts.com/episodes/360-facebook-authentication?autoplay=true. I'm 4 minutes in and all I've done so far is bundle the gem omniauth-facebook and added,

omniauth.rb

OmniAuth.config.logger = Rails.logger

Rails.application.config.middleware.use OmniAuth::Builder do
  provider :facebook, ENV['my id here...'], ENV['my secret code here...']

end

and then when I go to http://localhost:3000/auth/facebook I get an error saying The parameter app_id is required.

Oh, now I see: you need to define environment variables to store your facebook_app_id and facebook_secret. You add them to your environment like this (assuming unix-like system):

Add this to the bottom of your ~/.bashrc file (or equivalent):

export FACEBOOK_APP_ID='your_id_here'
export FACEBOOK_SECRET='your_secret_here'

Then open a new terminal to be sure they get loaded in the environment.

At last, in your omniauth.rb initializer you type exactly:

Rails.application.config.middleware.use OmniAuth::Builder do
  provider :facebook, ENV['FACEBOOK_APP_ID'], ENV['FACEBOOK_SECRET']
end

Read more about the topic here, for example.

You can also use dotenv gem to handle environment variables.

You can set the keys on the ENV variable as dgilperez says, or remove the ENV and write it directly.

Rails.application.config.middleware.use OmniAuth::Builder do
  provider :facebook, 'FACEBOOK_APP_ID', 'FACEBOOK_SECRET'
end

if you put the source code in a public repo (like github), use the ENV variable as it's more secure.
