Tutorial for restful_authentication on Rails with Facebook Connect in 15 minutes

26 February 2009
150 comments

[Update (10 April 2010): we've edited the tutorial to bring it up to date with the current incarnations of Facebook Connect, Facebooker and Rails.]

Back in June 2007 I wrote a popular tutorial on writing Facebook platform applications with Ruby On Rails. Time has moved on and Facebook has launched Facebook Connect which allows you to integrate Facebook into your own sites allowing authentication, registration, friend connecting, and Facebook feed posting in the context of your application. Mashable has a great post on 10 great implementations of Facebook Connect including Joost, Vimeo and Disqus.

At Made By Many we are fans of the possibilites of Facebook Connect for lowering barriers to registration, extracting social graph and injecting your social media functions into the daily online life of users. There is little point trying to create a “new” facebook on your site. Your unique social proposition lies elsewhere with your content, community and tools.

People have found the integration of Facebook Connect tricky and while great libraries like facebooker handle the API part, actually getting the profile linking and integration flow is harder. So I’ve written this tutorial to integrate the most commonly used starter plugin for authentication and registration in Ruby On Rails, restful_authentication, with Facebook Connect to allow your users to login and register through Connect.

First of all, let’s state what this integration is going to achieve:

As a user I can register to the site through entering my details so I can access all that great functionality
As a user I can login to the site through my entered username and password
As a user I can register to the site through Facebook Connect so I don’t have to fill in that form
As a user I can login to the site through Facebook Connect so I don’t have to remember two passwords
As a user I can connect my existing site user with my Facebook Connect user so I can later login through Facebook Connect

We also have a constraint we need to consider:

As a user if I register a user through entering my details and later login through Facebook Connect I want to make sure I retain my old user account

So read on and I’ll have you Connected in 15 minutes. We will first create a standard restful_authentication Rails application. I’m going to user mysql for this example
We will first create a standard restful_authentication Rails application.

rails -d mysql connect_tutorial
cd connect_tutorial

Then we need to install the restful authentication plugin:

cd vendor/plugins
git clone git://github.com/technoweenie/restful-authentication.git restful_authentication
cd ../..
./script/generate authenticated user sessions

Next, we create our database:

rake db:create
rake db:migrate

Now move include AuthenticatedSystem from the Sessions Controller to the Application Controller.

Start the server and browse to http://localhost:3000/signup. Bingo, Restful Authentication in 3 minutes. Don’t create any users yet we need to make to add some fields to connect up our accounts.

We need two extra columns for our users: one to store the Facebook user ID and another to store a special hash of our users email address which we can use to later match new Facebook users to existing accounts to take care of our constraint. Let’s create a migration for that:

script/generate migration add_users_fb

Edit the migration so that it looks like this:

def self.up
  add_column :users, :fb_user_id, :integer
  add_column :users, :email_hash, :string
  #if mysql
  execute("alter table users modify fb_user_id bigint")
end
def self.down
  remove_column :users, :fb_user_id
  remove_column :users, :email_hash
end

The ask Rake to run the migration:

rake db:migrate

For the Facebook heavy lifting, we are going to use the facebooker plugin. This will handle the API level communication for us.

script/plugin install git://github.com/mmangino/facebooker.git

You are now going to have to create a Facebook Application on Facebook to get your API key and secret. Head over to http://www.facebook.com/developers/createapp.php

picture-3

(Enter your own application name)

Facebook Connect setup screen

Take a note of the api_key and secret and add these to config/facebooker.yml. Also, make sure you set the callback_url to your local development server.

development:
  api_key: {YOUR_KEY}
  secret_key: {YOUR_SECRET}
  canvas_page_name:
  callback_url: http://localhost:3000/
  pretty_errors: true
  set_asset_host_to_callback_url: true
  tunnel:
    public_host_username:
    public_host:
    public_port: 4007
    local_port: 3000
Then, back at Facebook, select the Connect tab on the left of the page and enter your Connect URL (this used to be called the Callback URL) – for the purposes of this tutorial, you should set this to http://localhost:3000/ – make sure you include the trailing slash or Facebook’s form will complain:

fb-connect-screen-2

Now we need to create a cross-domain receiver file for Facebook Connect to callback on. Luckily, facebooker can do that for us, but make sure you have configured your facebooker.yml file correctly, or the generator will bomb out:

script/generate xd_receiver

We need to initialise the Facebook Connect on every page. This consists of 3 things:

adding a namespace declaration for FBML
adding the Facebook Connect Javascript
initialising the Javascript

Luckily facebooker can do some of this for us, so we create a generic layout index.html.erb

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
<html xmlns="http://www.w3.org/1999/xhtml" xmlns:fb="http://www.facebook.com/2008/fbml">
<head>
<%= javascript_include_tag :defaults%>
</head>
<body>
<%= fb_connect_javascript_tag %>
<%= init_fb_connect "XFBML"%>
<%=yield%>
</body>

And add the following to ApplicationController


layout 'index'
before_filter :set_facebook_session
helper_method :facebook_session

You are now ready to roll with some Facebook Connect tags. Add the following to the bottom of sessions/new.html.erb


<p>or login with Facebook connect</p>
<%= fb_login_button('window.location = "/users/link_user_accounts";')%>

And the following to users/new.html.erb


<p>or register with Facebook connect</p>
<%= fb_login_button('window.location = "/users/link_user_accounts";')%>

We also add another registration field for name


<p><%= label_tag 'name' %><br/>
<%= f.text_field :name %></p>

These are going to create FBML tags which the Facebook connect Javascript will render as our Connect buttons

Start (or restart) the server and go to http://localhost:3000/login. The result should look like the following screenshot. If not, retrace your steps to make sure you’ve not done something wrong.

picture-5

Now it’s time to integrate. We need to do three main things

When you are logged in through a Facebook session then login through restful authentication
Link accounts between Facebook and Restful Authentication
Create accounts when someone login or register with facebook.

In order to do this, we first need to edit lib/authenticated_system.rb. Change the current_user method to:


def current_user
  @current_user ||= (login_from_session || login_from_basic_auth || login_from_cookie || login_from_fb) unless @current_user == false
end

Also, we need to add the following method:


def login_from_fb
  if facebook_session
    self.current_user = User.find_by_fb_user(facebook_session.user)
  end
end

This will handle the seamless login for us. Now we need to add to our User model as follows:


#find the user in the database, first by the facebook user id and if that fails through the email hash
def self.find_by_fb_user(fb_user)
  User.find_by_fb_user_id(fb_user.uid) || User.find_by_email_hash(fb_user.email_hashes)
end
#Take the data returned from facebook and create a new user from it.
#We don't get the email from Facebook and because a facebooker can only login through Connect we just generate a unique login name for them.
#If you were using username to display to people you might want to get them to select one after registering through Facebook Connect
def self.create_from_fb_connect(fb_user)
  new_facebooker = User.new(:name => fb_user.name, :login => "facebooker_#{fb_user.uid}", :password => "", :email => "")
  new_facebooker.fb_user_id = fb_user.uid.to_i
  #We need to save without validations
  new_facebooker.save(false)
  new_facebooker.register_user_to_fb
end
#We are going to connect this user object with a facebook id. But only ever one account.
def link_fb_connect(fb_user_id)
  unless fb_user_id.nil?
    #check for existing account
    existing_fb_user = User.find_by_fb_user_id(fb_user_id)
    #unlink the existing account
    unless existing_fb_user.nil?
      existing_fb_user.fb_user_id = nil
      existing_fb_user.save(false)
    end
    #link the new one
    self.fb_user_id = fb_user_id
    save(false)
  end
end
#The Facebook registers user method is going to send the users email hash and our account id to Facebook
#We need this so Facebook can find friends on our local application even if they have not connect through connect
#We hen use the email hash in the database to later identify a user from Facebook with a local user
def register_user_to_fb
  users = {:email => email, :account_id => id}
  Facebooker::User.register([users])
  self.email_hash = Facebooker::User.hash_email(email)
  save(false)
end
def facebook_user?
  return !fb_user_id.nil? && fb_user_id > 0
end

This allows authentication to look up users either from their stored Facebook ID, or a hash of their email address. It also adds methods for our creating and linking. After any user is created we need to register them we Facebook Connect so add to the User model


after_create :register_user_to_fb

In the previous view’s Facebook Connect login button we added an after login JavaScript callback. This is to link our accounts after a user has gone through the callback process. We need to add this to the user controller


def link_user_accounts
  if self.current_user.nil?
    #register with fb
    User.create_from_fb_connect(facebook_session.user)
  else
    #connect accounts
    self.current_user.link_fb_connect(facebook_session.user.id) unless self.current_user.fb_user_id == facebook_session.user.id
  end
  redirect_to '/'
end

Don’t forget to add a route for this, as follows (make sure you replace the existing route for :users)


map.resources :users, :collection => {:link_user_accounts => :get}

Finally we need to have somewhere to go after login. Let’s create a home page under Users controller users/home.html.erb


<% if logged_in? %>
<h2>You are logged in as <%= current_user.name %></h2>
<% if current_user.facebook_user? %>
<fb:profile-pic uid="<%= current_user.fb_user_id%>" facebook-logo="true" size="thumb" ></fb:profile-pic>
<p><a href="#" onclick='FB.Connect.logoutAndRedirect("/logout")'>Logout</a></p>
<% else %>
<p>why don't you connect with your facebook account</p>
<%= fb_login_button('window.location = "/users/link_user_accounts";')%>
<p><%= link_to 'Logout', logout_path%></p>
<% end %>
<% else %>
<h2>You are not logged in!</h2>
<p><%= link_to 'Signup', signup_path%> or <%= link_to 'Login', login_path%></p>
<% end %>

And map it to root and delete public/index.html


map.root :controller => "users", :action => "home"

And it’s done. Stop the clock. Start (or restart) the server and go to http://localhost:3000/login and press the big connect button

Hope this helps you guys. You can find more Facebook Connect documentation on the developer wiki. I’m hoping to add to this tutorial with posting to the feed and connecting with friends so follow me @stueccles on Twitter for updates. You can find the code for this tutorial at github.

Great tutorial, Thanks a lot!

Andrew Timberlake 27 February 2009

Thanks for this tutorial

If you’re using a recent version of Rails, you don’ need the line: execute(”alter table users modify fb_user_id bigint”)
You can just add :limit => 20 to your migration column definition

Brett Jackson 28 February 2009

When I click the connect button on the register page, I get this error, and I cannot figure it out. Any help?

NoMethodError in UsersController#home

undefined method `set_facebook_session’ for #

Brett Jackson 28 February 2009

I’m not able to get this working, is it possible you could email the source code to me, at brettbj.jackson+ror@gmail.com ?

brettbj.jackson+ror@gmail.com

Brett Jackson 28 February 2009

I even downloaded the source code, and I still get errors.

stuart 28 February 2009

HI Brett.

Your first issue sounds like you don’t have facebooker installed.

For the downloadable source, you do need to change config/facebooker.yml to have you own Facebook application key and secret.

There was an issue with resful_authentication in the github source as a submodule but i’ve just commited it instead.

Nice post, thanks !

Vincent 03 March 2009

Thanks, very useful !

Chris 05 March 2009

Thank you for a timely and well-written article!

iv 05 March 2009

I had to set_asset_host_to_callback_url: false in order to make it work

Imran Rashid 10 March 2009

Great tutorial! Just what I was looking for, this saved a ton of time.

Avishai 11 March 2009

Nice tutorial. I’m having 2 problems though:

* I get a NoMethodError in UsersController#link_user_accounts; Rails doesn’t seem to recognize “facebook_session”. I have facebooker installed and have successfully authenticated using the normal Facebook API methods.

* The FB Connect login buttons aren’t rendering, because using the helpers causes this JavaScript error in Firebug:
Element.observe is not a function:
Element.observe(window,’load’, function() {
FB_RequireFeatures([“XFBML”], function() {
FB.Facebook.init(’6d5xxxxxxxxx’,’/xd_receiver.html’);
});
});

Anyone know what might be wrong? Thanks!

Shane 16 March 2009

why do i get a 500 internal server error when it redirects to “link_user_accounts”? could i possibly get the code in a zip?

stuart 16 March 2009

Avishai.

Make sure you have in your layout and before_filter :set_facebook_session in your Application Controller.
You should include
include AuthenticatedSystem

in your Application Controll after before_filter :set_facebook_session.

If all else fails check out the code on Github http://github.com/madebymany/restful-authentication-facebook-connect-tutorial/tree/master

rockaBe 16 March 2009

many thanx for this very understandable helping tutorial.
great job!!

i encountered a strange problem with the facebooker-plugin, during following your tut:
after creating the views for the login i started my server and tried to connect to http://localhost:3000/login/ i got this strange error:

http://localhost:3000/login/

http://localhost:3000/login/

Status: 500 Internal Server Error Content-Type: text/html

Status: 500 Internal Server Error Content-Type: text/html

which is caused by the layout.erb in vendor/plugins/facebooker/templates/.
This is easily corrected by renaming the file to layout.erb.erb, but what is wrong with my settings, that this crazy behaviour appears?

layout.erb
vendor/plugins/facebooker/templates/

layout.erb.erb

stuart 16 March 2009

Try layout.html.erb

Philip Hallstrom 16 March 2009

The 500 Internal Server Error is an issue with recent rails and mongrel. It is being triggered by facebooker due to a bug in the code that determines the layout to use for ‘pretty errors’. See here for how to fix the server error:

http://billkirtley.wordpress.com/2009/03/03/failsafe-handling-with-rails/

And until facebooker is updated (they know about it so should be soon) set pretty_errors to false in the yml config file.

Philip Hallstrom 16 March 2009

Question for you about linking accounts. It seems to leave the existing user account in the system. That is, I signup via FB. Logout. Signin via restful auth. Link my accounts. There is now an orphaned user record. I want to make sure I haven’t missed something. Is this the expected behaviour?

stuart 18 March 2009

Hi Philip,

Little confusing because if you signup using FB you shouldn’t then be able to signin with restful auth. You can then create a new account using restful auth though and try to link with the facebook account, it then actually moves over the linked account to the new one and leaves an orphaned record of the first. This is expected behaviour but in a production application you may want to merge them or inform the user.

Michal Frackowiak 18 March 2009

Unfortunately (as of 18. Mar) facebooker does not work with Rails 2.3. I hope this could be fixed soon.

don ferguson 18 March 2009

I’ve got facebooker integrated with my rails project, and can log in via facebook connect. But I’m having some trouble getting it to log out. I call the FB.Connect.logoutAndRedirect(“/logout”) method, and my own logout method is called. The session is reset, but the facebook_session keeps coming back from the dead.
I think it’s because set_facebook_session rematerializes it using the cookie (in secure_with_cookies!). Is there something else I need to do to stop it from doing this?

FWIW, it does work for me in the sample app… thanks.

don ferguson 18 March 2009

So it turns out that the problem was that the cookies weren’t being cleared. I’m not sure why they were being cleared in the sample app, but I suspect it’s because the sample uses cookie-based sessions, rather than database-backed sessions which is what my app uses. Anyway, my solution was to modify controller.rb to expose clear_fb_cookies!, and call it when logging out.

Dan 19 March 2009

I get the following error when trying to run this app,

undefined method `second’ for [“window.location = \”/users/link_user_accounts\“;”]:Array

The error arises from
vendor/plugins/facebooker/lib/facebooker/rails/helpers/fb_connect.rb:57:in `fb_login_button’

Any ideas?

Dan

Dan 19 March 2009

Sorted, was using rails 2.1.1. It only works with 2.2.2

Michael Camilleri 19 March 2009

Further to what @Avishai said, I had a similar error conflict when I followed these instructions. In my case the problem was jQuery. You either have to get rid of jQuery or look into running jQuery in noConflict mode (http://docs.jquery.com/Using_jQuery_with_Other_Libraries) since it appears the Facebook JS requires Prototype.

http://docs.jquery.com/Using_jQuery_with_Other_Libraries

Hope that helps!

Andrew Kingsley 19 March 2009

Hi Michael

Thanks for the tip but could you please elaborate more how to override this behaviour of jQuery or disable it?

Daniel Colegate 20 March 2009

Great tutorial. I have the connect_tutorial working fine.

However, in my real app I keep getting the following error when I call User.create_from_fb_connect.

undefined method `fb_user_id’ for :false:Symbol

Has anybody else seen this problem?

The link_fb_connect works fine for users who already registered through restful_authentication. Just can’t seem to create a new user.

Andrew Kingsley 20 March 2009

hmmmm i guess i found a bug the script couldnt locate prototype.js libararies and all other required ones too its nothing to do with jQuery. here is the server dump

Sorry for the previous post I assesed what I was doing wrong

siong1987 21 March 2009

You can actually use:

@@@ruby

add_column :users, :fb_user_id, :bigint

Andrew Kingsley 22 March 2009

well it wasn’t the fb_user_id column, i forgot to create database migration for ‘name’ while creating a field for it.
I kept on getting NoMethod error after login and something like undefined method `name’ for #
so in my case the following migration did the trick.

def self.up
add_column :users, :name, :string
end

def self.down
remove_column(:users, :name)
end

Alexander 27 March 2009

Hi. Can you advice, how can I post newsfeed through connect or get info about friends. Thanks

Chris 31 March 2009

One small note. During the “Install restful authentication” section, I believe you want to add a line to:

cd vendor/plugins before you do the git

Thanks for the great tutorial.

Vidal Graupera 08 April 2009

Thanks so much for posting this detailed tutorial.

I spent a lot of time trying to get fb connect to work with facebooker without success, before I found this article.

Your instructions worked perfectly.

Reed Law 10 April 2009

I get this error on the canvas page:

Missing template users/home.erb in view path app/views

The file name is home.html.erb as per this tutorial. It doesn’t give this error on my server, only when accessed through Facebook.

Dustin Anderson 12 April 2009

Worked perfectly for me… THANK YOU!!!

Ed Park 15 April 2009

Thanks so much for this example. I’ve learned a ton from it.

I did notice a documentation bug (#1) and a code bug (#2).

#1: on this web page, you have a call to register_user_to_fb, when that user was created from the fb_user data:
def self.create_from_fb_connect(fb_user)
new_facebooker.register_user_to_fb
end

In your source code (which I downloaded), that call is not made.

Your source code is correct I assume, there is no reason to call register_user_to_fb.

#2: for the bug, let’s assume the following use case: your user has never visited your site, and the user attempts to login via Facebook Connect.

The user is created in the users table via the create_from_fb_connect method.

However, you have this line of code in the User model:

after_create :register_user_to_fb

So the register_user_to_fb method is called after create_from_fb_connect.

The problem with register_user_to_fb is that it assumes that we have the email, which we won’t if the user only logged in via Facebook Connect. So this line of code:

self.email_hash = Facebooker::User.hash_email(email)

is essentially doing this:

self.email_hash = Facebooker::User.hash_email(“”)

and the hash email for a Facebook Connect user is always:
0_d41d8cd98f00b204e9800998ecf8427e

To fix that, I wrapped the body of the register_user_to_fb method with a test to make sure the email wasn’t blank/nil.

Hope that makes sense.

Thanks again for contributing this page to the community. I would have spent hours researching to figure out how to do what you have already provided.

Cheers,
Ed

Daniel 17 April 2009

Thanks for a great tutorial!

However, it fails in Safari 4. The logout pattern described above, and in the example-code fails to log out the user. The session is recreated after a few seconds (my guess – for as long as it takes to get a new one from FB) – and magically, the user is logged in (and in my case – redirected again).

Firefox 3 does not display the same erratic behavior!

Matt 21 April 2009

I’m running Rails 2.2.2 and have two problems…

before_filter :set_facebook_session fails but this hack seems to be a work-around…

def facebook_session
if session[:facebook_session]
session[:facebook_session]
elsif params[:fb_sig_user]
set_facebook_session
end
end

The other issue is that it fails with a undefined local variable or method `fb_connect_javascript_tag’

Any ideas?

Troy 22 April 2009

can someone help instruct me through this process for a dolphin site? I would really appreciate it, i’m having a hard time following the tut. in-jazz@hotmail.com

Pavel Zaitsev 22 April 2009

callback_url should not have ‘/’ otherwise it will generate url that rails cannot handle.

Stephen Hood 27 April 2009

Thanks for the great tutorial!

One question, though: early on, you mention that we can’t get the facebooker’s email address. But then later in the method “register_user_to_fb”, it appears you have the email address and generate its hash. Where is this email address coming from?

Andrea 27 April 2009

I found this tutorial really interesting, but I had one problem when running the final application. If I log in I get the following message when I go back to the root of the page.

“Facebooker::Session::SessionExpired in Users#home”
“Session key invalid or no longer valid” …

I think I’m missing something, but I tried several times to follow the steps explained and nothing changed.

I tried then to download the demo you gave us on github, but when running rake:migrate I get an error on the facebooker plugin.

Thanks a lot!

gonzo 30 April 2009

Thanks so much Stuart – right on the money.
Kudos!

Christian 02 May 2009

Please note. ClickToFlash does not work with FBML. If you have it installed, test to see if the site works in Firefox, if it does: ClickToFlash is at fault.

That bug just cost me ALOT of frustration.

GreenAlgae 12 May 2009

If you are using jRails and jQuery, it will only work if you specify js => :jquery in the options:

init_fb_connect “XFBML”, :js => :jquery

RobL 19 May 2009

I’m also getting the problem with

undefined local variable or method `fb_connect_javascript_tag’ for #

It appears that the FbConnect helper is never loaded, and I can’t work out why. Surely you don’t need to require the helper file directly.

I’m using Rails 2.3.2, any ideas on how to get this to work?

jerik 01 June 2009

Hi tried to use this tutorial for rails 2.3. Get as well a similar error-message like Andrea (27. April 2009), but already in action: link_user_accounts

Facebooker::Session::SessionExpired in UsersController#link_user_accounts

any ideas how to solve?

Cheers — jerik

jerik 04 June 2009

works now. My fault was that I had specified two times “map.resources :user”. Removing one solved the problem.

#map.resources :users
map.resources :users, :collection => {:link_user_accounts => :get}

Cheers — jerik

Ben Hutton 09 June 2009

thanks for the tutorial. very helpful.

Has anyone tried writing controller tests for the fbconnect functionality? I can’t seem to figure out how to, and there seems to be a HUGE lack of info/documentation on the internet…

John 14 June 2009

hi, excellent tutorial, think i’m halfway to getting it to work with an old app that uses acts_as_authenticated but getting this error when i try to login:

Facebooker::Session::MissingOrInvalidParameter in AccountController#link_user_accounts

Invalid email hash specified.

any ideas?

Archer 02 July 2009

It seems as if the registration field you add for ‘Name’ under the register with facebook connect doesn’t actually do anything at all. Is there a way to make this pass an email address that the user enters?

paulie 04 July 2009

Hi,
i have used your tutorial for facebook integration. ihave done well , but i have struck with the error something like

/vendor/plugins/facebooker/lib/facebooker.rb:54:in `[]=’: can’t convert Hash into String (TypeError)
in the console.

can you please help me in this regard.
Thank you.

Mark 09 July 2009

Hi there.

How do I make it so a User has more fields and where would I put the RESTful stuff to make all that happen and editable? I tried to do it myself but it did not work at all.

Thanks

Andrew W. 10 July 2009

It looks like Facebook’s application creation pages/forms have changed from your screenshots. The new application forms that facebook has are quite a bit more confusing. What does that simple old “Callback URL” correspond to in Facebook’s new forms? Thanks.

Andrew W. 10 July 2009

Ok, I think I found the answer to my own question. In the updated Facebook create application pages, go to the “Connect” tab, and put that “Callback URL” in the “Connect URL” field. With that in place, I followed the rest of the tutorial, and everything worked fine. Thanks!

jrgoodner 12 July 2009

Hey there, I had a problem running “script/generate xd_receiver” on ubuntu 9.04, rails 2.2.2.

If anyone else encounters this issue:

Problem was that I hadn’t installed curl libraries, and i was lacking the typhoeus gem–follow instructions at http://github.com/pauldix/typhoeus/tree/master to clear things up.

http://github.com/pauldix/typhoeus/tree/master

jrgoodner 12 July 2009

Most of everything seems to be working okay–but I can’t see my FB pic when I sign in…anyone have any pointers?

Is my facebooker.yml sheet filled out incorrectly? What is supposed to go in “callback_url”–I’m just running my local server, so should “callback_url” be http://localhost:3000?

http://localhost:3000?

Cagan Senturk 14 July 2009

Thanks for the post.

There is a small bug in the Logout functionality. It’s actually caused by the
User.find_by_fb_user method.

The problem happens if one registers to the site with the ‘same’ email address as he uses to login to Facebook but does not ‘connect’,

If the user is logged in to facebook, hitting ‘logout’ on the separate site will not work because the
User.find_by_fb_user method will return a user as the email_hash matches.

ram 24 July 2009

I am a beginner, and find it very tough to follow. Can you make the steps easier for beginners to follow please?

Mat 24 July 2009

Hi,
I have trouble getting the recommendations working with jQuery instead of prototype. I even cloned the whole example from github, changed the app so that it uses jquery. The init was also changed:

init_fb_connect “XFBML”, :js => “jquery”

Still, not even the connect button does render.

Has anybody else tried to get it to work with jQuery?

Any ideas are appreciated!
mat

vinod 25 July 2009

hi im following all the instructions above but when i load my site i get this error everytime…
any ideas what could be wrong?

undefined method `fb_login_button’

i was facing some difficulties installing facebooker – later i isntalled the gem and copied the dir to vendors/plugins. that should do it right?

any ideas?
thanks

James 29 July 2009

Got an implementation of facebooker and Facebook Connect working on Merb thanks to this article. Life saver!

vinod 01 August 2009

Yeah i could get it to work with few changes here and there! great tutorial though.

Dave L 04 August 2009

Hey, thanks a lot for the tutorial! Everything works really well, but I have been struggling with the scenerio where one logs into my site with their fb account, then goes to facebook, logs in and then logs out through facebook. The facebook_session is still valid and so it shows FB.Connect.logoutAndRediret(), but it does not work. Has anyone run into this problem? Any possible solutions?

Jon Crawford 10 August 2009

I have a question about passwords. I have a password validation in my user model that requires a 6+ character password. The password in the example above is simple “”. This means that a user can’t update their profile after registration without running into validation errors.

Additionally, if a user’s password is saved as “”, doesn’t that open them up to some serious security risks? Someone could log into their account simply by entering their username. Correct?

Any input on this would be awesome!

mail@joncrawford.com

Yang 20 August 2009

Hi,

Thank you so much for the great tutorial!

I am not using restful_authentication, but most of what you describe via facebook connect should work.

I am a noob, and I have two quick, simple questions.

After facebook login popup window appears and I put in my facebook user id and password, it brings up my site inside the popup window again. All the sites I’ve seen would close the popup window after authentication was successful.

Also, I do want a new user who authenticates through facebook choose his/her username and one additional parameter after successful authentication.

So, if I want to close the popup window and redirect the user to pick a username after successful facebook authentication, how would I go about doing it? Do I need to specify “Post-Authorize Callback URL” in facebook application settings? Or just change “link_user_accounts” function in User controller?

Thank you so much in advance!

Regards,

Paul 02 September 2009

Facebooker and Facebook have changed a few things since this tutorial.

1) You need to edit your facebook.yml file before you run ruby script/generate xd_receiver, or else you may run into errors. How to set up facebook.yml is explained further in the tutorial.

2) Facebook no longer, at least for the time being, supports localhost web developing via iFrame. You have to publish to a server in order to connect with Facebook.

I found this site:http://sentientmobile.com/jshaw/blog/post/2009/01/12/Developing-Facebook-app-on-your-local-machine.aspx kinda explains a way to develop on localhost. I still have yet to find a good clean way to do it.

PJ 08 September 2009

I followed this tutorial and had a problem where facebook_session was always returning nil. I fixed it by specifying “127.0.0.1:3000″ instead of “localhost:3000″ as the “Connect URL” setting on Facebook, and as the “callback_url” field in facebooker.yml. After making these changes, facebook_session no longer returns nil, and I can happily develop locally.

PJ 08 September 2009

Scratch that. Missed something stupid. I’ve been reading that you must now use a public host through which to develop Facebook Connect.

PJ 08 September 2009

I hope someone is still moderating this thread and can delete my previous two posts. After banging my head against the table for nearly 5 hours, I’ve discovered that you MUST have a trailing slash on your “Connect URL.” So while http://localhost:3000 won’t work, http://localhost:3000/ will. Argh!

http://localhost:3000
http://localhost:3000/

Elin 09 September 2009

ah, no need to worry. Stuart loves comments and now he can brag about having nearly 80 on his blog post , which is by far more than what any of the rest of us have:)

lucky 30 September 2009

Hi can u guide how to publish message on my facebook friends profiles.

Andrés Mejía 02 October 2009

I’m getting the following exception when I click the Connect button:

Processing UsersController#link_user_accounts (for 127.0.0.1 at 2009-10-02 15:09:01) [GET]

NoMethodError (You have a nil object when you didn’t expect it!
The error occurred while evaluating nil.user):
app/controllers/users_controller.rb:35:in `link_user_accounts’

Apparently, the method facebook_session is not defined. Is this somehow related to Rails 2.3.2?

kiran 06 October 2009

HI Stuart Grate Tutorial,

I am facing logout problem.

when I am logout then it’s show me “you are logout from both side ” message but
after refresh page it’s showing as login but facebook session has clear(logout from facebook).

I am trying second way

I am calling restful logout method code below

def destroy
self.current_user.forget_me if logged_in?
cookies.delete :auth_token
clear_fb_cookies!
reset_session
redirect_to( ‘/’ )
end

In code I am calling clear_fb_cookies! .
It’s work but only logout from my application not from facebook

Please help…..

Tyler 07 October 2009

Installed and works great! Thanks for the tutorial!

One problem though:

I want to be able to use the traditional:

rather than
Logout

Logout

Is there a way to do this? I’m trying to do as few checks as to whether or not the user is a facebook_user or not. It just really makes my views MESSY.

Tyler 07 October 2009

Could you tell what exactly you mean by “expose clear_fb_cookies!” ? I believe I have the same problem.

Tom 14 October 2009

Thanks Stuart. Very helpful. However, in some cases facebook is not following the correct callback_url. I have it set to :

callback_url = http://www.example.com/

http://www.example.com/

and the xd_receiver.html is sitting at document root (/public). For some reason sometimes facebook is requesting:

http://www.example.com/?sessionid=somesessionid&sessionkeysomesessionkey&next_url=www.example.com/xd_receiver.html

I have an app filter at the root so this is redirecting facebook to a login page.
I am going to try to set up a specific route to get around this, but I thought i’d see if you had seen this and had any ideas. Thanks

Michael Schwanzer 20 October 2009

Hey Andrés,

I am having the same problem – did you find a workaround so far? It only happens when the user is NOT logged in to facebook (has no cookies).

Thanks, michael

Monica 20 January 2010

Hello,

I am a complete newb… I really want to create a Facebook app, but I’m afraid I don’t follow much of what’s going on in your tutorial or how many things I would need to install on my computer to make this work. I’ve taken a couple of C++ classes, but I don’t have much other experience in programming. Please let me know if you think this is possible for me to learn and what resources might be useful to me.

Thank you so much

Michael 20 January 2010

$ script/generate xd_receiver

gave me an error “Facebooker::AdapterBase::UnableToLoadAdapter”

I configured the config/facebooker.yml file and then re-ran the command to generate an xd_receiver and got the expected output…

create public/xd_receiver.html
create public/xd_receiver_ssl.html

It might help to switch these sections of the tutorial around. Evidently there was an update to facebooker on 7/31/2009 that makes the new sequence of steps necessary.

This looks like it would be a great tutorial, but I can’t even get restful_authentication installed :( i follow the directions step-by-step and still get an error that authenticated is not a generator when I try to generate the scaffolds. Where exactly do I put the restful_authentication folder and/or do I put its data into my rails app folder directly?

‘extracting social graph’

I’m not really sure that that is supposed to convey. This looked a promising article, but as soon as I hit ‘gobbledegook’ instead of clear, well-written English, and in the second paragraph, at that, it had the same effect as a slow-loading web page.

I skipped the rest of the article down to the comments form and took a minute or so to write this. That I took the trouble is in respect of what looked to be interesting and good quality technical content. If clarity were added, and pseudo-socio-market-speak omitted, readers such as me would stay long enough to do justice to your work.

It’s a shame.

PotHix 09 February 2010

Æ!!

Really good post!
I’m having a problem with rails 2.3. I’m reading the Rails 2.3 release notes (http://guides.rubyonrails.org/2_3_release_notes.html) and there was a lot of changes about CGI::Session that probably broke the facebook gems (rfacebook and facebooker).

http://guides.rubyonrails.org/2_3_release_notes.html

Somebody having the same problem? Some Fix?

Alessandro 28 April 2010

Great tutorial, everything works great. I’m having a problem with Facebook Connect automatically logging me in however. Here is how it happens:

Let’s say at some point I Facebook Connected in my app, so it has created a User record for me.
One day I go to facebook.com and log in straight from there. I then visit my app, and it has automatically logged me in! I don’t like this assumption that just because there is a Facebook session active, I want to log in to my app. I want it to log in ONLY AFTER I have hit the Facebook Connect button (that’s how most sites do it at least).

What’s responsible for this automatic login? I’m assuming it’s the before_filter :set_facebook_session, but how can I fix this behavior?

Thanks!

dan 28 April 2010

im trying to add facebook login capabilities and found your tutorial to be exactly what i was looking for
however im trying to use as gem and not plugin
ive added require ‘tasks/facebooker’ to rakefile and changed set_asset_host_to_callback_url: false
othere then that, ive followed your instructions very closely

the problem i am having is i do not see a blue facebook connect button

any ideas why not?

Karl He 03 May 2010

Great tutorial, helped out a lot!

I have a question: Can this give me access to the Facebook Graph APIs “for free”? Or do I have to separately authenticate with OAuth, even if the account is already connected? I’d like to be able to grab my users’ friends in one go with linking accounts, if possible.

Werner Pyke 05 May 2010

Absolutely awesome!
I’m completely new to rails and have messed around with the standard scaffolding, Bort, hobo and others but always ended up feeling like I was wading through more stuff than I needed. I’m completely sold on the idea of my app supporting only FB Connect and this is ultra-lightweight.

I think I’ll go ahead and strip out the code that allows non-FB signup and login next. I feel like I never again want to do any data management that I don’t have to and love the declarative approach that Rails offers.

Ryan 31 May 2010

If you’re getting strange javascript errors such as:
ActionController::RoutingError (No route matches “/prototype.js” with {:method=>:get, :canvas=>false})

Go to config/facebooker.yml and make sure your callback_url has NO TRAILING SLASHES!

It must be:

http://localhost:3000

instead of:

http://localhost:3000/

add these lines to your layout…

and you need to include following script after login button (in sessions/new.html.erb file)

FB.init(“YOUR_API_KEY_HERE”, “/xd_receiver.htm”);

I encounter this error when trying to create a user with the facebook connect button:

No action responded to link user. Actions: create, create_facebook_session, create_facebook_session with secret, facebook_params, facebook_session, facebook_session_parameters, link_user_accounts, new, one_or_true, redirect_to, render_publisher_error, render_publisher_interface, render_publisher_response, set_facebook_session, top_redirect_to, wants_interface?, and zero_or_false

has anyone encountered this problem? I scrolled thru the comments and I believe I’m the only one here. Perhaps there is a bug in the facebooker plugin for rails 2.3x?

Great tutorial!

I’ve been looking around for a tutorial like yours.

Been a great help, thanks!

How can I access the User object at a later time in a controller? i.e. If I want to insert the User’s ID as part of a database record (they post a comment, and i need to put their id on it)

Also, how can I access the Facebook user object via a controller? Thank you!! Great tutorial :)

Looks like I’m having a similar problem as Murali Dharan in the previous comment. Any help would be appreciated!

Maybe this is the cause of the problem Murali and I described in the previous 2 comments:

The line of code referred to in this part of the error trace:

/Users/mark/Documents/VM2/gvmp/vendor/plugins/facebooker/lib/facebooker/models/user.rb:655:in `register’
is:
Facebooker::Session.create.post(“facebook.connect.registerUsers”,:accounts=>users.to_json) do |ret|

So maybe the error’s “Unknown method” is “facebook.connect.registerUsers”.

This guess is supported by this web page:
http://developers.facebook.com/docs/reference/rest/connect.registerusers/
which says:
“This method has been deprecated.”

But surely there must be a fix for this that most of the affected websites have already implemented? I googled around for clues, but no luck yet…

Googling some more, it’s looking to me like facebooker is not keeping up with changes in Facebook Connect, and there are other plugins/gems that are keeping up, so it’s better to use them instead.

Here’s more on the deprecated methods:
http://thinkdiff.net/facebook/deprecated-rest-api-methods-2010/

and here are some suggested alternatives to facebooker:

My colleague already recommended Omniauth - I should have listened!

so for those of us who got stuck on the very first command,
rails -d mysql connect_tutorial

It should be changed to
rails new connect_tutorial -d mysql
