Facebooker talk - Jan 2009 - Possible Bug in Facebooker''s Connect support (secure_with_cookies!) ?

Facebooker folks ---

I was having trouble running the facebook-connect tutorial (
http://www.elevatedrails.com/articles/2009/01/02/announcing-facebooker-support-for-facebook-connect/
) --- I could log my test-account in, but I couldn''t get a valid
facebook_session to show up.

I''ve traced the problem to Facebooker''s
"secure_with_cookies!" method
and realized that if the user happens to have an infinite session, his
''expires'' cookie is set to "0", which means that
Facebooker will think
that his cookie expired in 1969 -- hence no facebook_session for
anybody with a persistent session key.

I''ve gotten the tutorial to run successfully if I check for a
persistent session_key in the method:

return unless (Time.at(parsed[''expires''].to_f) > Time.now)
||
(parsed[''expires''] == "0")

Don''t know if the method is written this way for a reason, but I
thought I''d let you all now anyway ...

Cheers,

Vince

Consider this:
"The smallest positive integer not definable in under eleven words."

Thanks! I pulled this in along with another fix from Kevin Lochner. I  
also bumped the version number to generate new gems.
