How can I use Django Social Auth to connect with Twitter?

Question

I'm trying to use the Django Social Auth package to connect with Twitter, but I'm having difficulty understanding how exactly to do this as I can't find any examples. I am assuming that Django Social Auth is the best package to use for this purpose.

I've looked at a few examples that use Facebook, and from this have added the following to my settings.py file:

AUTHENTICATION_BACKENDS = (
    'social_auth.backends.twitter.TwitterBackend',
    'django.contrib.auth.backends.ModelBackend',
)

# overwriting default templates
TEMPLATE_CONTEXT_PROCESSORS = (    
    'django.core.context_processors.static',
    'django.core.context_processors.debug',
    'django.core.context_processors.i18n',
    'django.core.context_processors.media',
    'django.contrib.messages.context_processors.messages',
    'social_auth.context_processors.social_auth_by_type_backends',
    'django.contrib.auth.context_processors.auth',
)

SOCIAL_AUTH_ENABLED_BACKENDS = ('twitter')
SOCIAL_AUTH_DEFAULT_USERNAME = 'new_social_auth_user'

# Social media login info:
TWITTER_CONSUMER_KEY         = 'xxx'
TWITTER_CONSUMER_SECRET      = 'xxxxxx'

# 'magic' settings
SOCIAL_AUTH_COMPLETE_URL_NAME = 'socialauth_complete'
SOCIAL_AUTH_ASSOCIATE_URL_NAME = 'associate_complete'

SOCIAL_AUTH_PIPELINE = (
    'social_auth.backends.pipeline.social.social_auth_user',
    'social_auth.backends.pipeline.associate.associate_by_email',
    'social_auth.backends.pipeline.misc.save_status_to_session',
    'social.pipeline.redirect_to_form',
    'social.pipeline.username',
    'social_auth.backends.pipeline.user.create_user',
    'social_auth.backends.pipeline.social.associate_user',
    'social_auth.backends.pipeline.social.load_extra_data',
    'social_auth.backends.pipeline.user.update_user_details',
    'social_auth.backends.pipeline.misc.save_status_to_session',
    'social.pipeline.redirect_to_form2',
    'social.pipeline.first_name',
)

SOCIAL_AUTH_FORCE_POST_DISCONNECT = True
SOCIAL_AUTH_SESSION_EXPIRATION = False 

In urls.py I've added the following lines:

url('', include('social_auth.urls')),
url(r'^twitter/', twitter_app, name='twitter_app')

And in a file called twitter.py I've added the following to create a view:

from django.contrib.auth import BACKEND_SESSION_KEY
from django.contrib.auth.models import AnonymousUser
from django.http import HttpResponse
from django.http import HttpResponseRedirect #dq
from django.shortcuts import render_to_response
from django.template.context import RequestContext

from django.views.decorators.csrf import csrf_exempt
from django.core.cache import cache

from social_auth.models import UserSocialAuth
from social_auth.views import complete as social_complete
from social_auth.utils import setting
from social_auth.backends.twitter import TwitterBackend


# twitter login    
def twitter_app(request):
    """twitter login"""
    if request.user.is_authenticated():
        return HttpResponseRedirect('done')
    else:
        return render_to_response('twitter.html', {'twitter_app_id':setting('TWITTER_CONSUMER_KEY'),
                                                'warning': request.method == 'GET'}, RequestContext(request))

I've then created a template file called twitter.html with the following structure:

{% extends "base.html" %}

{% block script %}

Login with <a href="{% url socialauth_begin 'twitter' %}">Twitter</a>

{% endblock %}

This results in the following error message:

The webpage at http://example.com/twitter/done has resulted in too many redirects.

I'm a little bit lost as to what I should be doing overall. I have created an app on twitter with my site url to generate the api/secret key. Any advice on what direction I should go, or links to working examples would be greatly appreciated.

I will give you a sample and this is a customize twitter login,

1. the name of the app is social
2. pip install Twython
3. create LOGIN_REDIRECT_URL, TWITTER_SECRET and TWITTER_KEY

settings.py

# Twitter settings
TWITTER_KEY = 'xxxxxx'
TWITTER_SECRET = 'xxxxxxxx'

models.py

class TwitterProfile(models.Model):
    user = models.ForeignKey(User)
    oauth_token = models.CharField(
        max_length=200
        )
    oauth_secret = models.CharField(
        max_length=200
        )
    screen_name = models.CharField(
        max_length=50, 
        blank=True, null=True
        )

    def __unicode__(self):
        return "{0}".format(self.user)

urls.py

urlpatterns = patterns('social.views',      
    url(
        r'^twitter/login/$', 
        "twitter_login", 
        name="twitter_login"
    ),

    url(r'^twitter/callback/$', 
        "twitter_callback", 
        name="twitter_callback"
    ),   
)

views.py

def twitter_login(request):
    twitter = Twython(
        twitter_token = settings.TWITTER_KEY,
        twitter_secret = settings.TWITTER_SECRET,
        callback_url = request.build_absolute_uri(reverse('social:twitter_callback'))
    )
    auth_props = twitter.get_authentication_tokens()
    request.session['request_token'] = auth_props
    return HttpResponseRedirect(auth_props['auth_url'])


def twitter_callback(request, redirect_url=settings.LOGIN_REDIRECT_URL):
    twitter = Twython(
        twitter_token = settings.TWITTER_KEY,
        twitter_secret = settings.TWITTER_SECRET,
        oauth_token = request.session['request_token']['oauth_token'],
        oauth_token_secret = request.session['request_token']['oauth_token_secret'],
    )

    authorized_tokens = twitter.get_authorized_tokens()

    try:
        profile = TwitterProfile.objects.get(screen_name = authorized_tokens['screen_name'])
        user = User.objects.get(pk=profile.user_id)
        user.backend = 'django.contrib.auth.backends.ModelBackend'

        if user.is_active:
            auth_login(request, user)
            return HttpResponseRedirect(reverse('app_name:url_name'))
        else:
            //failed back to login
            return HttpResponseRedirect(reverse('app_name:login'))
    except TwitterProfile.DoesNotExist:
        screen_name = authorized_tokens['screen_name']
        oauth_token = authorized_tokens['oauth_token']
        oauth_token_secret = authorized_tokens['oauth_token_secret']

        //create new twitter profile
        //create new user here
        //authenticate the new register user then login
        .........

template

<a href="{% url social:twitter_login %}">Twitter</a>
