With Rails, how to convert code which used Facebooker to using Facebooker2?

There is code to use Facebooker gem (which uses the old Facebook REST API). Does someone have experience how to conver开发者_运维技巧t those code to using Facebooker2, which uses the new Facebook Graph API?

For example, Facebooker has Facebooker::Session and Facebooker::User and they are both gone in Facebooker2.

I can't find too much docs on the two sets of API.

I've written an article about converting your Facebooker app to Facebooker2. This also means that should change from FBML to iFrame if you haven't already:
