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

There are several options:

• Set the environment variables from the command line:

  export FACEBOOK_APP_ID=your_app_id
  export FACEBOOK_SECRET=your_secret
  

  You can put the above lines in your ~/.bashrc

• Set the environment variables when running rails s:

  FACEBOOK_APP_ID=your_app_id FACEBOOK_SECRET=your_secret rails s
  

• Create a .env file with:

  FACEBOOK_APP_ID=your_app_id
  FACEBOOK_SECRET=your_secret
  

  and use either Foreman (starting your app with foreman start) or the dotenv gem.
