I'd like to point to several probably important facts:

I work with custom user model - https://pastebin.com/yWSvVUbe

I work with rest-framework-jwt in my usual authentication (register and login) and I wanted to use drfso2 for the possibility of social authentication (facebook and google).

settings.py - https://pastebin.com/nqnbNusT

v1/urls.py - https://pastebin.com/vu9Lghrq

Thank you very much!!!

Answer 1

Simply add this line and done!

DRFSO2_URL_NAMESPACE = 'drfso2'

And if you have not given a URL for the pattern, then do that too; otherwise, you’re all done.

Answer 2

I am not sure what are the configurations of your settings and urls as the files with the code you provided as links to pastebin are apparently removed and no longer available, but I tackled and resolved the similar issue the following way.

If you use default urlconf setting for endpoints handling social authentication, this issue should not appear at all, so you can just use:

urlpatterns = patterns(
    ...
    (r'^auth/', include('rest_framework_social_oauth2.urls')),
)

If you have some custom urlconf settings and you wish to place the endpoints for social authentication elsewhere, do not set the variable DRFSO2_URL_NAMESPACE in settings, just add the name parameter to your urls.py:

path('oauth/login/', SocialLoginView.as_view(), **name='authorize'**).

And the issue should disappear.

Hope it could help someone.

Answer 3

You have to set the DRFSO2_URL_NAMESPACEparameter on your setting.py file.

The URL namespace is the one where you placed your auth API.

Check your main urls.py file:

from django.contrib import admin
from django.urls import path, include

urlpatterns = [
    path('admin/', admin.site.urls),
    path('api/auth/', include('myproject.myauthapp.api.urls', namespace='auth-api')),
    ...
]

With my example, you have to set it to 'auth-api':

DRFSO2_URL_NAMESPACE='auth-api'
