Rails 3 authentication with OpenID, Twitter or Facebook
Can you suggest some working example of it? I tried Authlogic and Devise withous success. UPDATE - June 2011 - I have been using the omniauth gem recently and I think it is a better solution than using the gems suggested in this answer. It works well with Devise and will give you everything you need in one gem. I created an engine that combines Devise and Omniauth and adds a controller to handle the callbacks. I have quite a few changes planned for the gem and right now I don't consider it a stable plugin, but you may be able to reuse some of the code in the gem: https://github.com/charlotte
