OAuth and Rails: Logging in With Twitter, Facebook, and More!
In this talk my goal was to start with a Rails 3.2 application with Devise installed and configured, and then show how easy it was to add OAuth login support using the omniauth gem ecosystem.
In addition to the slides, the application I extended is available on GitHub. Clone the repo at whazzmaster/omniauth-on-rails and you can work through the steps I took during the talk to try it for yourself.
