URL Rewriting issue - missing app name from _path and _url posted by Tyler Godfrey @ Tue, 02 Dec 2008 13:31:06 -0000

Tyler Godfrey — Tue, 02 Dec 2008 13:31:06 -0000

Uninstalling just Rails and its immediately associated gems (activeresource, actionpack, etc.) didn’t work. However, blowing away all of my installed gems and reinstalling them did.

I’m up and running. Thanks for the help!

When I’m running the application off of my laptop using an SSH tunnel, it does not work. When I run it directly on a server using the same version of Rails and Facebooker, it does work.

It looks like the issue is with my installation of Rails and Facebooker on my laptop. I just tried uninstalling and reinstalling both via gems, and that didn’t work. I’m next going to blow away all of the gems on my machine and start over.

Problems w/ Ferret posted by RC @ Mon, 01 Dec 2008 16:45:51 -0000

RC — Mon, 01 Dec 2008 16:45:51 -0000

I’m currently attempting to implement Ferret (full-text search) using the acts_as_ferret plugin to the facebooker app I’m working on, but there are problems with the pagination(using will_paginate).

When I paginate a regular list of records, the pagination works fine but getting a listing back from a ferret query causes the page indexing not to work. Trying to access any page but the 1st page of paginated listings returns this error:

ActiveRecord::RecordNotFound in FoosController#show
Couldn’t find Foo with ID=search

Has anyone else come across this problem?
btw, I’m currently using Ferret in development

Just re-installing should do it. In theory, you can use sub-modules but I’ve never gotten that to work.

I just double checked Facebooker and it works fine for me with Rails 2.2

Here’s what I have in routes.rb:


  map.root :controller=>"test", :action=>"index" 
  map.name_test '/name_test',:controller=>"test", :action=>"index"

In index.fbml.erb


This is a test <%= link_to "With a link to a named route", name_test_path%> and an <%=link_to "absolute link", root_url%>

Does a simple testcase like that work? I just cleaned up The facebooker tests to work with Rails 2.2 and all of our tests pass.

The callback URL is not actually a link – the forum interpreted it that way.

I should have thought about using an earlier version of Rails. I would assume there may be issues if Facebooker has not been tested with 2.2.

I appreciate the help!

Is your callback URL actually a link? I’m guessing that was added by the forum code.

I’m not running any applications on Rails 2.2, that might be the problem. Let me take a look to see if I can duplicate this.

Hi Mike,

Thanks for your reply.

After reinstalling the Facebooker plugin using script/plugin install git://github.com/mmangino/facebooker.git, the method started working again.

Slightly off topic, but since script/plugin update facebooker didn’t work for me, is
there any way to use script/plugin update for plugins installed from a git
repository? Or is reinstalling the only way currently?

I am having a problem getting the URL rewriting to work correctly. In the example in Chapter 2 (page 22) <%=new_invitation_path%> gets interpreted as /invitations/new. If I change it to <%=new_invitation_url%>, it is interpreted as:

apps.facebook.com/invitations/new

Basically, my app name is getting dropped by the URL rewriter, near as I can tell.

Here’s my facebooker.yml:


development:
  api_key: 913870fe21e5e6e7de326c391d3b0c9d
  secret_key: ********************************
  canvas_page_name: motivatus_tg
  callback_url: <a href="http://9a3400e6.fb.joyent.us:3000">http://9a3400e6.fb.joyent.us:3000</a>

My environment:

Rails 2.2.2
Facebooker r224 (installed from SVN source trunk)

Any ideas?

This refers to Page 98-99 of the Textbook:

After defining the attack_feed_template method, I was able to register it correctly using the
AttackPublisher.register_attack_feed command in script/console.
However, when I made a change to the attack_feed_template method and attempted to re-register the
template, I got the following error:

ArgumentError: wrong number of arguments (0 for 1)

I was able to get around this problem by opening up mysql and deleting the template record directly from the
facebook_templates table and then running AttackPublisher.register_attack_feed again to register it
successfully as a new template, but does anyone know what the cause of this error is? Does the Facebooker
library not pass some required parameter when registering an existing template? Or is there something else I’m
missing?

Good find! As much as I’d like to claim it as a printing error, it’s more likely an author error. Can you add this as an errata at http://www.pragprog.com/titles/mmfacer/errata ? That will remind me to fix it if we do another release of the PDF.

Thanks and good luck with your application!

'Session key invalid or no longer valid' notification issues posted by Paul Fioravanti @ Thu, 27 Nov 2008 00:40:11 -0000

Paul Fioravanti — Thu, 27 Nov 2008 00:40:11 -0000

Thanks very much for the reply, Mike.

I’m testing out all of my actions via the web (2 Facebook users running on web browsers on seperate machines),
and not by script/console.

I tried de-authorizing the application on both users and then re-authorizing it, and reloading the fixtures into the
development database to try and get a clean slate, but I still got the
user_to_user notifications require a session error. Checking out the users table under mysql, it seemed that the session_key value is always NULL when a new user is added.

After a bit of reading ahead, it seems that the issue was in the set_current_user method. Working on page 93,
my set_current_user method in app/controllers/application.rb still looked like it did when it was first
implemented on page 38 of the text:

def set_current_user
    self.current_user = User.for(facebook_session.user.to_i)
end

The above User.for method doesn’t pass in a second facebook_session parameter, so I guess that’s why I was
getting NULL session_key values. I cross-referenced the official downloaded code in
chapter3/karate_poke/app/controllers/application.rb and found there that the User.for method is passing in the second facebook_session parameter. Perhaps this is a printing error in the text?

Anyway, when I changed the code to how it is on page 125 below, the notifications got sent and I was able to view them as expected:

def set_current_user
  set_facebook_session
  # if the session isn't secured, we don't have a good user id
  if facebook_session and 
    facebook_session.secured? and 
    !request_is_facebook_tab?
      self.current_user = User.for(facebook_session.user.to_i,facebook_session) 
  end
end

Have you used the application recently as the user who you are sending the notification from?

By default, Facebook sessions are only valid for about an hour from the time the user last uses your application. If you’re sending notifications via the web, this won’t be a big deal because each request renews the session. If you’re using script/console, you’ll need to make sure you visit your application in a browser once an hour or so.

I’ve tried looking back over what I’ve done so far, but I guess I’m finding the
Facebook session stuff pretty confusing. Is no one else having similar session-related problems?

Hi there,

I’m currently having fun working my way through the text but have hit a wall on page 93, Sending Notifications.
I’ve implemented the attack_notification and send_attack_notification methods and have tried to get
notifications sent from and to my test Facebook users but I’m getting the following error:

facebook.notifications.send (0) Facebooker::Session::SessionExpired:
Session key invalid or no longer valid

How do I generate new session keys for my test Facebook users?
Any help appreciated.

Problem with adding the created App posted by Stephane Arcos @ Tue, 25 Nov 2008 00:25:13 -0000

Stephane Arcos — Tue, 25 Nov 2008 00:25:13 -0000

Hello there,
I’m closed to release my first app, thanx to this amazing book, but I have an issue when a new user try to install it(‘allow’ in new Facebook terms).

My server (the production one) is hit two times :
1 – using this url : apps.new.facebook.com/app_name/


Processing PollsController#index 
  Parameters: {... "action"=>"index", "controller"=>"polls", "fb_sig_added"=>"0" ...}

2 – After clicking the “Allow”


Processing PollsController#index 
   Parameters: {"installed"=>"1", "action"=>"index", "auth_token"=>"ebe62ef2f6da55d7e3d2565f17676ca9", "controller"=>"polls"}
...
Rendering polls/index

ActionView::MissingTemplate (Missing template polls/index.html.erb in view path /home/soxosin/fb_polls/app/views):

It looked like the second request does not go thru Facebooker, I have tried to change the ‘Post-Add URL’ in the Facebook app settings (currently set to http://apps.new.facebook.com/app_name) but same result.

My main route is :

map.root :controller=>"polls" , :action=>"index"

(I’ve tried map.connect ’’, :controller => “polls”, map.polls ’’, :controller=>”polls” , :action=>”index”)

It is really just this step causing problem, the app is correctly added and if I navigate to apps.new.facebook.com/app_name/ it is functionnal.

Any Idea ?
TIA
Stephane

There was an API change after the publication of the book. I believe you now need to pass in four parameters. I’ll see if I can make the last one optional.

Can someone tell me what that means? Maybe the book assumes the reader has some technical knowledge, but that statement has just gone straight over my head and I’m 100% lost.

EDIT: Okay, I was just watching the screencast “Rails Development for the Facebook Platform – Part 1: Building an App From Scratch” and was Tunnlr was suggested I tried that out, but when I run the “rake facebooker:tunnel:start” command, this is the output:
