How to set settings.LOGIN_URL to a view function name in Django 1.5+

Assuming you've set the path name in urls.py, you can use 'application_name:view_name' as the LOGIN_URL value in settings.py, like so:

application/urls.py

...
path('login/', views.login, name='login'),
...

project/settings.py

LOGIN_URL = 'application:login'

https://docs.djangoproject.com/en/2.1/ref/settings/#login-url

Django computes this url in django.contrib.auth.views:redirect_to_login function as:

resolved_url = resolve_url(login_url or settings.LOGIN_URL)

Therefore you should set it as string:

LOGIN_URL = 'my_app.views.sign_in'

Also in settings.py you can use reverse_lazy function:

from django.core.urlresolvers import reverse_lazy
LOGIN_URL = reverse_lazy('my_app.views.sign_in')
