[Facebooker-talk] Session key invalid or no longer valid
This may be related to Aaron''s question on Jan. 30. However in my case I doing Facebook Connect using Facebooker for my site. Following the Facebook Connect tutorial it does create a session and show the user as logged in. For now I have the same ''fb'' controller just to demo log in. However if the user logs out at facebook.com and then refreshes fb/index on my site, I get "Session key invalid or no longer valid" on the line that outputs @facebook_session.user.name. Just FYI if I output @facebook_session.user.to_s it does give me the uid. If you look at the stack trace below you''ll notice that it passes through a number of actions that test for existence and validity of the session. It has a problem in the Error class of parser.rb. I would think it should catch the problem a lot earlier than in parser.rb. Any thoughts on how to troubleshoot and/or workaround this? I''m on Rails 2.1.1. ======================================= Facebooker::Session::SessionExpired in Fb#index Showing fb/index.html.erb where line #10 raised: Session key invalid or no longer valid Extracted source (around line #10): 7: <%= fb_login_button%> 8: 9: <% if facebook_session %> 10: <h2>You are logged in as <%= facebook_session.user.name %></h2> 11: <% else %> 12: <h2>You are not logged in!</h2> 13: <% end %> vendor/plugins/facebooker/lib/facebooker/parser.rb:487:in `process'' vendor/plugins/facebooker/lib/facebooker/parser.rb:15:in `parse'' vendor/plugins/facebooker/lib/facebooker/service.rb:20:in `post'' vendor/plugins/facebooker/lib/facebooker/session.rb:473:in `post_without_logging'' vendor/plugins/facebooker/lib/facebooker/session.rb:484:in `post'' vendor/plugins/facebooker/lib/facebooker/logging.rb:27:in `log_fb_api'' vendor/rails/activesupport/lib/active_support/core_ext/benchmark.rb:8:in `realtime'' vendor/plugins/facebooker/lib/facebooker/logging.rb:27:in `log_fb_api'' vendor/plugins/facebooker/lib/facebooker/session.rb:483:in `post'' vendor/plugins/facebooker/lib/facebooker/models/user.rb:120:in `populate'' vendor/plugins/facebooker/lib/facebooker/model.rb:35:in `name'' app/views/fb/index.html.erb:10:in `_run_erb_47app47views47fb47index46html46erb'' -- - Adeel -------------- next part -------------- An HTML attachment was scrubbed...

[Facebooker-talk] Session key invalid or no longer valid
I''m using a rescue. I tried advancing this discussion a couple weeks
ago - the problem is that to really *know* that the session is valid,
you have to try using it (i.e., hit the facebook rest server with a
request). I think it''s a waste to
constantly ping the facebook server just to make sure you don''t get an
invalid session error when you''re not expecting it, especially given
that this scenario will be low-frequency with respect to total requests.
So here''s what I did in facebooker/rails/controller.rb:
module Facebooker
module Rails
module Controller
def self.included(controller)
controller.rescue_from
Facebooker::Session::SessionExpired, :with => :facebook_session_expired
end
def facebook_session_expired
clear_fb_cookies!
clear_facebook_session_information
flash[:error] = "Your facebook session has expired."
redirect_to root_url
end
I''m hesitant to add this to facebooker because i''m not
convinced
everyone will want to do it this way, and
it probably means adding another parameter like "expired_session_url"
so that this exception handling
works out of the box (since not everyone will redirect to root_url).

[Facebooker-talk] Session key invalid or no longer valid
Thanks, this looks like it should do well for now. However it''s not
catching
the exception... must be some other config I have wrong. Odd.
module Facebooker
module Rails
module Controller
include Facebooker::Rails::ProfilePublisherExtensions
def self.included(controller)
controller.extend(ClassMethods)
controller.before_filter :set_adapter
controller.before_filter :set_fbml_format
controller.helper_attr :facebook_session_parameters
controller.helper_method :request_comes_from_facebook?
controller.rescue_from Facebooker::Session::SessionExpired, :with =>
:facebook_session_expired
end
def facebook_session_expired
clear_fb_cookies!
clear_facebook_session_information
flash[:error] = "Your facebook session has expired."
