Which is the best 0auth gem for a rails app?

I'm going to add Oauth autenthication to my rails web app. Since I don't want to reinvent the wheel, have you got some ruby gem to suggest to add this kind of featur开发者_StackOverflow中文版e?

I would say that this advice is now superseded. I'd suggest you use OmniAuth instead, possibly with Devise if you need normal auth as well.

There are 2 OmniAuth specific RailsCasts that walk you through exactly what's needed: OmniAuth Part 1 and OmniAuth Part 2

Have a look at these:

Pelle's plugin at github tutorial is here

and the second one is oauth2 with some examples
