Facebooker talk - Nov 2008 - Iframe ensure_authenticated

Anyone have any good ideas on how to use ensure_authenticated_to_facebook
before_filters in a canvas iframe application that also has external
interface?  I had been checking controller.format == "fbml" in an fbml
canvas app but looking at perhaps migrating to full iframe and having some
challenges figuring out authenitcation.  Would appreciate if anyone knows of
any resources haven''t found to much via google that I could apply via
ruby
on rails.

        Thanks --ken s.

Hey Ken,

So I''ve got an app with iframes, but we''re using the fbml
fb:iframe tag
instead.  To keep the pages distinct from app pages, I''m using the
format of iframe, so:

home_url(:format => :iframe)

make a link to:

/home.iframe

which points to the template;

app/view/home/index.iframe.erb

so now I can have normal HTML templates, and iframe ones.  They use the
same controllers so you don''t need to repeat the biz logic.

Then you can rely on the fbml page that wraps your app to ensure the
application is added (and the first iframe hit will have params to build
a facebook sesssion).  Not quite as powerful as a real iframe app for
facebook, but maybe you can use fbml and only fall back to iframe where
needed.

Good luck!
