Python-social-auth Authcanceled Exception

I'm using python-social-auth in my Django application for authentication via Facebook. But when a user tries to login, they have been redirected to the Facebook app page, and they

Solution 1:

python-social-auth is a newer, derived version of django-social-auth.

AlexYar's answer can be slightly modified to work with python-social-auth by modify settings.py with following changes:

1. Add a middleware to handle the SocialAuthException

   MIDDLEWARE_CLASSES += (
       'social.apps.django_app.middleware.SocialAuthExceptionMiddleware',
   )
   

2. URL to redirect to, when an exception occurred

   SOCIAL_AUTH_LOGIN_ERROR_URL = '/'

3. Note that you also need to set

   DEBUG = False

That's all or read http://python-social-auth.readthedocs.org/en/latest/configuration/django.html#exceptions-middleware

Solution 2:

you can create a middleware and catch any exceptions, exception list: https://github.com/omab/python-social-auth/blob/master/social/exceptions.py in this case your AuthCanceled Exception.

middleware.py

from social.apps.django_app.middleware import SocialAuthExceptionMiddleware
from django.shortcuts import HttpResponse
from social import exceptions as social_exceptions

classSocialAuthExceptionMiddleware(SocialAuthExceptionMiddleware):
    defprocess_exception(self, request, exception):
        ifhasattr(social_exceptions, 'AuthCanceled'):
            return HttpResponse("I'm the Pony %s" % exception)
        else:
            raise exception

settings.py

MIDDLEWARE_CLASSES = (
        .....
        'pat_to_middleware.SocialAuthExceptionMiddleware',
)

This is slight modification of @Nicolas answer and this works for me.

middleware.py

from social.apps.django_app.middleware import SocialAuthExceptionMiddleware
from django.shortcuts import render
from social.exceptions import AuthCanceled

classSocialAuthExceptionMiddleware(SocialAuthExceptionMiddleware):
    defprocess_exception(self, request, exception):
        iftype(exception) == AuthCanceled:
            return render(request, "pysocial/authcancelled.html", {})
        else:
            pass

settings.py

MIDDLEWARE_CLASSES += (
'myapp.middleware.SocialAuthExceptionMiddleware',
)

Solution 4:

The 2018 answer:

1. Add SocialAuthExceptionMiddleware middleware to your config:

   MIDDLEWARE_CLASSES = [
       ...
       'social_django.middleware.SocialAuthExceptionMiddleware',
   ]
   

2. Set SOCIAL_AUTH_LOGIN_ERROR_URL in your config:

   SOCIAL_AUTH_LOGIN_ERROR_URL = '/login'

Now when you have DEBUG = False, your users will get redirected to your login page when they click cancel in social auth provider's page.

When DEBUG = True you will still see the error page in your browser during development.

Solution 5:

Just add in

MIDDLEWARE_CLASSES = ( 'social_auth.middleware.SocialAuthExceptionMiddleware', )

and something like

LOGIN_ERROR_URL = '/'
