Django Facebook by Thierry Schellenbach (http://www.mellowmorning.com)

First

Facebook is changing their authentication flow. Expect Django Facebook to upgrade in the coming week. You will need to upgrade to a new version of Django Facebook to keep things working. Read more about the changes here: http://developers.facebook.com/blog/post/499/ http://developers.facebook.com/roadmap/ (migrations) http://developers.facebook.com/docs/authentication/ Their migration is now scheduled for September 1st so we still have some time :)

Please contribute code :)

This project is actively maintained and I appreciate improvements to the code.

Contact me here or @tschellenbach

New in Version 2.0 Alpha

• canvas page support for facebook applications
• mobile facebook registration support (tested with titanium FB flow)
• less requirements (jinja, view decorator, django notify and cjson requirements removed)
• fql support
• django static support

About Django Facebook

Django Facebook allows you to connect to the Facebook Open Graph API. Integrated with Django it becomes easy to setup a login/register via Facebook flow for your users.

Features

• Access the Facebook API, from:

  • Your website (Using javascript OAuth)
  • Facebook canvas pages (For building facebook applications)
  • Mobile (Or any other flow giving you a valid access token)

• Django User Registration (Convert Facebook user data into a user model)
• Use Facebook data to register a user with your Django app. Facebook connect using the open graph API.
• Facebook FQL access

Works best with (not required)

• Django registration
• Django 1.3
• Django static files

TODO (again help is appreciated!)

• simplify these instructions
• separate user data conversion and FB api improvements
• fully replace the facebook GraphAPI which they no longer support
• add nice exception classes to the facebook official sdk replacement

Installation

Download the source code or use pip install django_facebook.

Create a Facebook App

In case you don't yet have a facebook app. You need an app to use the open graph api and make the login process work. You can create a facebook app at this url: http://www.facebook.com/developers/createapp.php

Settings

Define the following settings in your settings.py file:

FACEBOOK_API_KEY
FACEBOOK_APP_ID
FACEBOOK_APP_SECRET

Url config, context processor, auth backend

add django facebook to your installed apps:

'django_facebook',

add this line to your url config:

(r'^facebook/', include('django_facebook.urls')),

add this line to your context processors (TEMPLATE_CONTEXT_PROCESSORS setting):

'django_facebook.context_processors.facebook',

add this to your AUTHENTICATION_BACKENDS setting:

'django_facebook.auth_backends.FacebookBackend',

Update your models

Add the following fields to your profile model:

about_me = models.TextField(blank=True, null=True)
facebook_id = models.IntegerField(blank=True, null=True)
facebook_name = models.CharField(max_length=255, blank=True, null=True)
facebook_profile_url = models.TextField(blank=True, null=True)
website_url = models.TextField(blank=True, null=True)
blog_url = models.TextField(blank=True, null=True)
image = models.ImageField(blank=True, null=True, upload_to='profile_images')
date_of_birth = models.DateField(blank=True, null=True)
raw_data = models.TextField(blank=True, null=True)

An abstract model is specified for convenience django_facebook/models.py FacebookProfileModel

Check the example

Right now you should have a working registration/connect/login in flow available at /facebook/connect/ Test if everything is working and ensure you didn't miss a step somewhere.

Common bugs

Django Facebook expects that you are using static files in order to load the required javascript. If you are not using staticfiles you should load facebook.js provided in the static directory manually.

Another common issue are the url matching settings from Facebook. Facebook requires you to fill in a domain for your application. In order for things to work with local development you need to use the same domain. So if you production site is www.mellowmorning.com you should run your development server on something like local.mellowmorning.com in order for facebook to allow authentication.

If you encounter any difficulties please open an issue.

Customize and integrate into your site

This is the hardest step of the install. For an example you can look at connect.html in the templates directory.

First load the javascript (it loads the facebook library asynchronously). I recommend that you insert this code at the bottom of your page.

<script src="{{ MEDIA_URL }}js/facebook.js" type="text/javascript"></script>
<script>
facebookAppId = '{{ FACEBOOK_APP_ID }}';
function facebookJSLoaded(){
FB.init({appId: facebookAppId, status: false, cookie: true, xfbml: true, oauth: true});
}
window.fbAsyncInit = facebookJSLoaded;
F = new facebookClass(facebookAppId);
F.load();
</script>

Subsequently implement a form which calls Facebook via javascript. Note that you can control which page to go to after connect using the next input field.

<form action="{% url facebook_connect %}?facebook_login=1" method="post">
<a href="javascript:void(0);" style="font-size: 20px;" onclick="F.connect(this.parentNode);">Register, login or connect with facebook</a>
<input type="hidden" value="{{ request.path }}" name="next" />
</form>

On a final note the Facebook javascript SDK requires you to place a 'fb-root' div somewhere on your page. (See the example).
