social' is not a registered namespace

Question

Im trying to implement google authentication but I got the following error:

django.urls.exceptions.NoReverseMatch: 'social' is not a registered namespace

i have like this in my login.html:

<a href="{% url 'social:begin' 'google-oauth2' %}"> Sign in with Google</a>

I also added this in my setting.py

SOCIAL_AUTH_URL_NAMESPACE = 'social'

url.py

urlpatterns = [
    path('admin/', admin.site.urls),
    path('register/', user_views.register, name='register'),
    path('profile/', user_views.profile, name='profile'),
    path('login/', auth_views.LoginView.as_view(template_name='users/login.html'), name='login'),
    path('login/', include('allauth.urls')),
    path('logout/', auth_views.LogoutView.as_view(template_name='users/logout.html'), name='logout'),
    path('', include('blog.urls')),
 
]

Does anyone know how to solve this?

Answer 1

Add the following in urls.py where the url with namespace 'begin' has been defined, before url pattern

app_name = 'social'

Answer 2

Try this:

<a href="{% url 'begin' 'google-oauth2' %}"> Sign in with Google</a>

Updated

Please fix the URL mapping conflict as mentioned by @John Gordon:

path('login/', auth_views.LoginView.as_view(template_name='users/login.html'), name='login'),
path('login/', include('allauth.urls')),

You can't have two identical url patterns since Django finds the first one and then doesn't go further down the list if the first is a match. You can name it anything else such as 'accounts', 'users', you get the idea like so:

path('accounts/', include('allauth.urls')),

Do this change then see what you get and report back. Also, please include the settings.py file with your question as a code section rather than a comment.
