Facebooker talk - Apr 2008 - facebook_session not working for me

Hey All,

I can''t get facebook_session to return anything but nil.

I''m following along in Mike Mangino''s pragmatic
programmer''s book
about creating invitations - and adding info to a profile...

There is a part where we are supposed to grab the @user to be able to
set the profile_fbml on it.
@user = facebook_session.user
@user.profile_fbml = render_to_string(:partial=>"profile",
:locals=>{:from=>params[:from]})

Anyway, it never worked for me... I did an @user.inspect and it''s just
nil.  facebook_session doesn''t return anything.

Any ideas?

Thanks in advance!
Dustin

Do you have the facebook_session method defined?
>From pg 50 from Mike''s latest release.
def facebook_session
   @facebook_session ||  returning Facebooker::Session.create do |session|
    session.secure_with!(session_key,facebook_id,1.day.from_now)
   end
end

Thanks Ken,

I could be wrong, but I''m pretty sure that facebook_session is being
defined on page 50 in the book so that it can be accessed in the
Model.  In my case, I''m just trying to call it from the controller...
so I should be able to call facebook_session in the controller ( I
think)?

Any other ideas?

Hey Dave, I''m definitely calling
ensure_application_is_installed_by_facebook_user in application.rb -
so if I hit the server directly (e.g. localhost:3000), it sends me to
a "You''ve already installed this app" page.

Anyway, thanks Dave, but it must be something else... any other ideas?

Thanks again for all the help.

Hey Dustin,

This is sounding a little familiar.  I am wondering if someone the
facebook_session in your sessions table( you are using db sessions right? )
doesn''t have a user for some reason.   Can you blow away your session
table
and see if things get better?

And also something isn''t making sense here,  you say that
facebook_session
doesn''t return anything?  But them you say @user is nil?  If
facebook_session was nil then you would blow up before setting @user, right?

Dave

Thanks Dave,

I deleted all the content in my session table - didn''t seem to change
much, but we''ll see.

Anyway, I noticed that when I hit the new action with a value in
params[:from], I get this error in my server log:

Filter chain halted as
[#<ActionController::Filters::ClassMethods::SymbolFilter:0x274f3e0
@filter=:ensure_application_is_installed_by_facebook_user>]
rendered_or_redirected.

Here is what my "invitations/new" action looks like:
  def new
    if params[:from]
      @user = facebook_session.user
      @user.profile_fbml = render_to_string(:partial=>"profile",
:locals=>{:from=>params[:from]})
    end
    @from_user_id = facebook_session.user.to_s
  end

For the record, I don''t have +protect_from_forgery :secret+ set to
anything in application_controller.rb

any ideas what I''m doing wrong?

Thanks again for all the help...

Dustin

The key is this line:

[#<ActionController::Filters::ClassMethods::SymbolFilter:0x274f3e0
@filter=:ensure_application_is_installed_by_facebook_user>]
rendered_or_redirected.

That means that your Rails app doesn''t think the user has the  
application installed. Can you paste in the params that Rails is  
receiving? I would also double check and make sure that you have the  
right API Key and Secret Key in your Facebooker.yml

I''ll take a look at that - but isn''t the point of the exercise
in the
book to get the user to install the app?

I''m following along in your book and having User A send User B an
invitation.  User B clicks to accept the invitation and install the
app... but it can''t set profile_fbml yet because User B
doesn''t have
the app installed...

What am I missing there?

Thanks for your help!!!

Here is the entry from the server log, including params:

Processing InvitationsController#new (for 127.0.0.1 at 2008-04-28
19:38:12) [GET]

When user B clicks to install the application, they should be  
redirected to a page asking them to install the application. That''s  
what the "ensure_application_is_installed_by_facebook_user" does. Is  
User B not asked to install the application?

Yes, User B is definitely asked to install the application - but it
never sends the correct content (the _profile.erb partial) to the
@user.profile_fbml

Again, here''s the new action in the invitations controller:

  def new
    if params[:from]
      @user = facebook_session.user

      @user.profile_fbml = render_to_string(:partial=>"profile",
:locals=>{:from=>params[:from]})
    end
    @from_user_id = facebook_session.user.to_s
  end

Thanks,
dustin

Hey Mike,

OK, so User A sends User B an invitation... User B receives the
invitation.  Inside the invitation, there is a button to add the app.
Under the button, is the following code:

onclick="return click_add_platform_app(47658, 14802292125,
0,1191078019,1,''MyAppName'',
''http://apps.facebook.com/my_app/invitations/new?from=1191078019'');"

You''ll notice that it''s going to direct the user to
/invitations/new -
with the params[:from] set.  So, in the new action, it should hit
these two lines ( these are from the new action):

@user = facebook_session.user
@user.profile_fbml = render_to_string(:partial=>"profile",
:locals=>{:from=>params[:from]})

However, it never even gets there because the user hasn''t added the app
yet.

I''m following along in the book and I feel like I''ve followed
this
section exactly - but either I''m missing something or the example has
an error... either way, I do appreciate the help everyone is giving on
this.

Dustin
