commenting with login w/twitter or facebook connect

Question

Im building my blog in rails and I want to enable comments I would like to have something posterous-like with a "facebook connect" and "login with twitter" option. The user can login with one of them and then post. No anonymous posts. I dont want to add more login-services, just stay simple (i.e. no disqus) How can I do this?

Accepted Answer

I would suggest authlogic, like Devenv said. The tutorial on Railscast is very helpful. Also the author of authlogic himself created an example application as a tutorial

Authlogic can be extended to work with facebook and twitter with authlogic plugins:

Facebook with authlogic_facebook_connect:

```
$ sudo gem install facebooker
$ script/plugin install git://github.com/kalasjocke/authlogic_facebook_connect.git
```

then you can follow the Readme of authlogic_facebook_connect on github

Twitter with authlogic_oauth:

```
$ sudo gem install oauth
$ sudo gem install authlogic-oauth
```

then you can follow the Readme of authlogic_oauth on github again

Now you can enable login via facebook or twitter. Authlogic can do a lot more than that. If you want to, you can enable your railsapp to use openid authlogic_openid, too.
