Trying to configure environment variables using fb app_id and app_secret

Question

I am following rails cast #85 here and the marked correct answer on stackoverflow here.

I am trying to use facebook "app_id" and "app_secret" to set as environment variables in rails.

my code is:

initializers/facebook.rb

FACEBOOK_CONFIG = YAML.load_file("#{::Rails.root}/config/facebook.yml")[::Rails.env]

config/facebook.yml

development:
app_id: abcdefg
app_secret: 123456
production:
app_id: abcdefg
app_secret: 123456

initializers/omniauth.rb

OmniAuth.config.logger = Rails.logger

Rails.application.config.middleware.use OmniAuth::Builder do

provider :facebook, FACEBOOK_CONFIG['abcdefg'], FACEBOOK_CONFIG['123456'], {:client_options =>   {:ssl => {:ca_file => Rails.root.join("cacert.pem").to_s}}}
end

When I set the environment variables in front of the app_id and app_secret ie FACEBOOK_CONFIG when I try login through facebook it returns a "app_id parameter is required" message. So this way is not working. I am wondering if there is some code missing or someone can see something I am doing wrong the environment variables are not being processed through facebook (where they were before without any ENV variables).

Answer 1

in your rails console try it

edit

require 'yaml'
yaml = YAML.load_file(File.expand_path("#{Rails.root}/config/facebook.yml"))
puts yaml

*edit 2 *

FACEBOOK_CONFIG = YAML.load_file("#{::Rails.root}/config/facebook.yml")[::Rails.env]

change to:

FACEBOOK_CONFIG = YAML.load_file(File.expand_path("#{Rails.root}/config/facebook.yml"))[::Rails.env]
