Django Rest Framework: backend not found - django

Question

I'm trying to create and authentication with github account to DRF.
why i get 404 error and can't get to github authentication page?
I provided the code extracts. If any information is required or you have any questions please let me know.
Here's the views.py
class BookViewSet(ModelViewSet):
queryset = Book.objects.all()
serializer_class = BooksSerializer
filter_backends = [DjangoFilterBackend, SearchFilter, OrderingFilter]
permission_classes = [IsAuthenticated]
filterset_fields = ['price']
search_fields = ['name', 'author_name']
ordering_fields = ['price', 'author_name']
def auth(request):
return render(request, 'oauth.html')
And here's the settings.py
# Application definition
INSTALLED_APPS = [
"django.contrib.admin",
"django.contrib.auth",
"django.contrib.contenttypes",

ROOT_URLCONF = "books.urls"
TEMPLATES = [

}
}
AUTHENTICATION_BACKENDS = (

'django.contrib.auth.backends.ModelBackend',
)
REST_FRAMEWORK = {
'DEFAULT_RENDERER_CLASSES': (

'DEFAULT_PARSER_CLASSES': (

}
SOCIAL_AUTH_POSTGRES_JSONFIELD = True
SOCIAL_AUTH_GITHUB_KEY = '-some github key'
SOCIAL_AUTH_GITHUB_SECRET = 'git secret'
My urls.py
router = SimpleRouter()
router.register(r'book', BookViewSet)
urlpatterns = [
path("admin/", admin.site.urls),
re_path('', include('social_django.urls', namespace='social')),
path('auth/',auth)
]
urlpatterns += router.urls
And a very simple template
oauth.html
Github
Page not found (404)
Backend not found
Request Method: GET
Request URL: http://127.0.0.1:8000/login/github-oauth2/
Raised by: social_django.views.auth
Using the URLconf defined in books.urls, Django tried these URL patterns, in this order:
admin/
login/str:backend/ [name='begin']
The current path, login/github-oauth2/, matched the last one.
You’re seeing this error because you have DEBUG = True in your Django settings file. Change that to False, and Django will display a standard 404 page.
