What's the best gem/plugin to develop a Facebook Canvas/iFrame App (Rails 2.3.8, Ruby 1.8.7)?

we're developing a Facebook Canvas App in Rails 2.3.8, we tried a couple of gems out there and for now we're using mini_fb but it's not really well documented and we're having some issue with the authentication/authorization process, and more importantly we couldn't find a tutorial on how integrate cucumber.

I know there're plenty of options out there: facebooker (too old?), oauth2 gem, omniauth, mogli and so on.

What we ideally need is:

• Support for Canvas/iFrame app (not just Facebook connect)

• Support for the new OAuth 2.0 for Canvas (beta) facebook docs & for the old REST API as well

• Documentation (very hard to find, also cause 开发者_开发问答Facebook API are in first place not so extensively documentend, especially for Ruby)

• Support/Documentation/Tutorials for Cucumber integration

• Cover basic API features like Wall posting, Friends handling ...

What's the best option in your opinion/past experience?

Thank you guys,

Take a look at Koala...

Very well documented and maintained.

Works with Ruby 1.8/1.9 & Rails 2/3
