Pyfb - A Python Interface to the facebook Graph API

This is an Easy to Use Python Interface to the Facebook Graph API

It gives you methods to access your data on facebook and provides objects instead of json dictionaries!

Django Facebook Integration Using Pyfb

It's easy to integrate pyfb with Django. Just see the following example:

settings.py

# Facebook related Settings
FACEBOOK_APP_ID = 'YOUR_APP_ID'
FACEBOOK_SECRET_KEY = 'YOUR_APP_SECRET_CODE'
FACEBOOK_REDIRECT_URL = 'http://www.YOUR_DOMAIN.com/facebook_login_success'

views.py

from pyfb import Pyfb
from django.http import HttpResponse, HttpResponseRedirect

from settings import FACEBOOK_APP_ID, FACEBOOK_SECRET_KEY, FACEBOOK_REDIRECT_URL

def index(request):
    return HttpResponse("""<button onclick="location.href='/facebook_login'">Facebook Login</button>""")

#This view redirects the user to facebook in order to get the code that allows
#pyfb to obtain the access_token in the facebook_login_success view
def facebook_login(request):

    facebook = Pyfb(FACEBOOK_APP_ID)
    return HttpResponseRedirect(facebook.get_auth_code_url(redirect_uri=FACEBOOK_REDIRECT_URL))

#This view must be referred in your FACEBOOK_REDIRECT_URL. For example: http://www.mywebsite.com/facebook_login_success/
def facebook_login_success(request):

    code = request.GET.get('code')

    facebook = Pyfb(FACEBOOK_APP_ID)
    facebook.get_access_token(FACEBOOK_SECRET_KEY, code, redirect_uri=FACEBOOK_REDIRECT_URL)
    me = facebook.get_myself()

    welcome = "Welcome <b>%s</b>. Your Facebook login has been completed successfully!"
    return HttpResponse(welcome % me.name)

urls.py

urlpatterns = patterns('',

    (r'^$', 'djangoapp.django_pyfb.views.index'),
    (r'^facebook_login/$', 'djangoapp.django_pyfb.views.facebook_login'),
    (r'^facebook_login_success/$', 'djangoapp.django_pyfb.views.facebook_login_success'),
)

Integration with JS SDK

You can also use the JS SDK for the facebook login (without making a redirection to facebook, just by opening a popup login window) and Pyfb for backend api calls. Here is how to do it:

index.html

<html>
    <head>

    </head>
    <div id="fb-root"></div>
    <script>

        function isConnected(response) {
            return response.status == 'connected';
        }

        function getLoginStatus(FB) {

            FB.getLoginStatus(function(response) {

                if (isConnected(response)) {
                    onLogin(response);
                }
                else {
                    FB.login(onLogin);
                }
            });
        }

        function onLogin(response) {

            if (isConnected(response)) {
                location.href = '/facebook_javascript_login_sucess?access_token=' + response.authResponse.accessToken;
            }
        }

        window.fbAsyncInit = function() {

            FB.init({
                appId      : '{{FACEBOOK_APP_ID}}',
                channelUrl : 'http://localhost:8000/media/channel.html',
                status     : true,
                cookie     : true,
                xfbml      : true,
                oauth      : true,
            });

        };

        (function(d){
             var js, id = 'facebook-jssdk'; if (d.getElementById(id)) {return;}
             js = d.createElement('script'); js.id = id; js.async = true;
             js.src = "http://connect.facebook.net/en_US/all.js";
             d.getElementsByTagName('head')[0].appendChild(js);
        }(document));

    </script>

    <body>
        <button onclick="location.href='/facebook_login'">Facebook Python Login</button><br/><br/>
        <button onclick="getLoginStatus(FB)">Facebook Javascript Login</button>
    </body>
</html>

views.py

from pyfb import Pyfb
from django.http import HttpResponse, HttpResponseRedirect
from django.shortcuts import render_to_response

from settings import FACEBOOK_APP_ID, FACEBOOK_SECRET_KEY, FACEBOOK_REDIRECT_URL

def index(request):
    return render_to_response("index.html", {"FACEBOOK_APP_ID": FACEBOOK_APP_ID})


#This view redirects the user to facebook in order to get the code that allows
#pyfb to obtain the access_token in the facebook_login_success view
def facebook_login(request):

    facebook = Pyfb(FACEBOOK_APP_ID)
    return HttpResponseRedirect(facebook.get_auth_code_url(redirect_uri=FACEBOOK_REDIRECT_URL))


#This view must be referred in your FACEBOOK_REDIRECT_URL. For example: http://www.mywebsite.com/facebook_login_success/
def facebook_login_success(request):

    code = request.GET.get('code')

    facebook = Pyfb(FACEBOOK_APP_ID)
    facebook.get_access_token(FACEBOOK_SECRET_KEY, code, redirect_uri=FACEBOOK_REDIRECT_URL)

    return _render_user(facebook)



#Login with the js sdk and backend queries with pyfb
def facebook_javascript_login_sucess(request):

    access_token = request.GET.get("access_token")

    facebook = Pyfb(FACEBOOK_APP_ID)
    facebook.set_access_token(access_token)

    return _render_user(facebook)


def _render_user(facebook):

    me = facebook.get_myself()

    welcome = "Welcome <b>%s</b>. Your Facebook login has been completed successfully!"
    return HttpResponse(welcome % me.name)

urls.py

urlpatterns = patterns('',
    (r'^$', 'djangoapp.django_pyfb.views.index'),
    (r'^facebook_login/$', 'djangoapp.django_pyfb.views.facebook_login'),

)

Facebook paginated lists (Included in version 0.4.0)

from pyfb import Pyfb

(...)
# Do the oauth authentication (see the django example above)
(...)

photos = pyfb.get_photos()

print "These are my photos:\n"
for photo in photos:
    print photo.picture

#Just call the "next" method to get the next page of photos!
more_photos = photos.next()

print "\nMore photos:\n"
for photo in more_photos:
    print photo.picture

more_more_photos = more_photos.next()

print "\nDo you want more?:\n"
for photo in more_more_photos:
