Setting Environment Variables in Rails 3 (Devise + Omniauth)

Question

I\'ve been trying to figure out how Ryan Bates, in his Facebook Authentication screencast, is setting the following \"FACEBOOK_APP_ID\" and \"FACEBOOK_SECRET\" environment

Answer 1

Here's another idea. Define the keys and values in provider.yml file, as suggested above. Then put this in your environment.rb (before the call to Application.initialize!):

YAML.load_file("#{::Rails.root}/config/provider.yml")[::Rails.env].each {|k,v| ENV[k] = v }

Then these environment variables can be referenced in the omniauth initializer without any ordering dependency among intializers.
