I've looked everywhere, I've followed the legendary 360 Facebook Authentication by Ryan Bates but I still can't figure out why I am getting this:
The parameter app_id is required.
I cannot figure out how to set these: ENV['FACEBOOK_APP_ID'] and ENV['FACEBOOK_SECRET']
What is the simplest way of setting these so that when I hit the service it successfully reads these variables from whatever they are supposed to be read from? I tried pasting the values I got from Facebook into config.ru but it seems that the values are not being read from here (app id and app secret) and I'm still getting the same error.
I don't know what I am missing.
Here is what I have so far:
omniauth.rb:
OmniAuth.config.logger = Rails.logger
Rails.application.config.middleware.use OmniAuth::Builder do
provider :facebook, ENV['FACEBOOK_APP_ID'], ENV['FACEBOOK_SECRET']
end
config.ru:
# This file is used by Rack-based servers to start the application.
require ::File.expand_path('../config/environment', __FILE__)
use Rack::Session::Cookie, :secret => '<my secret is here>'
use OmniAuth::Builder do
provider :facebook, ENV['FACEBOOK_APP_ID'], ENV['FACEBOOK_SECRET'], :scope => 'email,read_stream'
end
run Rails.application
