Why doesn't Django 2.1 login_required work when parameter is present

Question

In urls.py I have:

path('/admin/', admin.site.urls),
path('/admin/login', login_required(admin.site.login)),
path('/customlogin/', include('customlogin.urls', namespace='customlogin'))

This redirects to a custom authentication view, specified in settings.LOGIN_URL.

When you go to /admin it redirects to /admin/login/?next=/admin, which does not redirect to LOGIN_URL. But when you go to /admin/login directly, everything works correctly.

Note: This worked correctly in Django 1.11.

Answer 1

To match the admin login url, your path should have a trailing slash. You also have to move your path above admin.site.urls, so that Django uses your decorated view.

path('/admin/login/', login_required(admin.site.login))
path('/admin/', admin.site.urls),
