[Facebooker-talk] Session Expired for Profile Publishing

[J Aaron Farr]

Ok.  I'm not having any success with publishing profile FBML.

Example code:

class WelcomeController < ApplicationController

  layout "facebook"
  ensure_application_is_installed_by_facebook_user

  def index

    @user = facebook_session.user
    ...
    @user.profile_fbml = render_to_string( :template => 'welcome/profile' )

  end

end


Results in this error:

Facebooker::Session::SessionExpired (Session key invalid or no longer valid):
    /vendor/plugins/facebooker/lib/facebooker/parser.rb:386:in `process'
    /vendor/plugins/facebooker/lib/facebooker/parser.rb:15:in `parse'
    /vendor/plugins/facebooker/lib/facebooker/service.rb:13:in `post'
    /vendor/plugins/facebooker/lib/facebooker/session.rb:399:in `post'
    /vendor/plugins/facebooker/lib/facebooker/models/user.rb:158:in
`set_profile_fbml'


Using a publisher isn't helping.  Publisher code:

  def profile_update(user, session_user = user)
    send_as :profile
    from session_user
    recipients user
    profile render( :partial => 'profile',:assigns => { :profile_user => user })
  end

  ...

  MyPublisher.deliver_profile_update( @user )

Results in:

Facebooker::Session::SessionExpired (Session key invalid or no longer valid):
    /vendor/plugins/facebooker/lib/facebooker/parser.rb:386:in `process'
    /vendor/plugins/facebooker/lib/facebooker/parser.rb:15:in `parse'
    /vendor/plugins/facebooker/lib/facebooker/service.rb:13:in `post'
    /vendor/plugins/facebooker/lib/facebooker/session.rb:399:in `post'
    /vendor/plugins/facebooker/lib/facebooker/models/user.rb:71:in `populate'
    /vendor/plugins/facebooker/lib/facebooker/model.rb:35:in `uid'
    /app/models/publisher.rb:14:in `profile_update'
    ...

The only way I can get it to work is to start a new session and use
code as suggested in the comments here:
    <http://apps.facebook.com/facebooker_tutorial/messaging/mini_feed>

like this:

     MyPublisher.deliver_profile_update(@user.create_session.user)


That seems very wrong.  Why do I need to (1) separately store the
session_key (as in the link above) and (2) create a new session in
order to update the profile FBML?

Any thoughts?
