    url(r'^', include('social.apps.django_app.urls', namespace='social')),

] + static(settings.MEDIA_URL, document_root=settings.MEDIA_ROOT)

And I`m trying to access the link using:
a href="{% url 'social:begin' 'google-oauth2' %}"

I will apreciate any kind of help.Thank you!

I just found the solution:
If you use django-rest-framework-social-oauth2 , on the url file you have to put both urls , or you will get this error :

url(r'^social/', include('social.apps.django_app.urls', namespace='social')),
url(r'^auth/', include('rest_framework_social_oauth2.urls')),

Thanks
