使用Devise的Rails 3：如何让某人使用他们的Facebook帐户登录？ [英] Rails 3 using Devise: How to allow someone to log in using their Facebook account?

问题描述

我有一个使用 Devise 进行身份验证的Rails 3应用程序。现在我需要允许某人使用他们的Facebook帐户登录。我认为这是Facebook Connect，但我也听说过Facebook Graph API这个词，所以我不知道我要求哪一个。

I have a Rails 3 application using Devise for authentication. Now I need to allow someone to log in using their Facebook account. I think this is called Facebook Connect, but I've also heard the term Facebook Graph API, so I'm not sure which one I'm asking for.

什么为了将Facebook Connect与Devise整合，我需要做些什么？

这个问题很漂亮老了一年前，Devise v1.2推出了 OmniAuth 支持。现在，Devise是v2.1（在撰写本文时），使用OmniAuth更容易。以下是Devise wiki上有关使用 omniauth- Facebook 宝石与Devise允许使用Facebook登录

This question is pretty old now. A year ago, Devise v1.2 introduced OmniAuth support. Now Devise is at v2.1 (as of this writing) and using OmniAuth is even easier. Here is a great tutorial from the Devise wiki on using the omniauth-facebook gem with Devise to allow sign-in using Facebook.
