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

Question

As of Django 1.5, you can set LOGIN_URL to a view function name, but I haven't been able to figure out how to specify it correctly.

LOGIN_URL = my_app.views.sign_in

...does not work. I get the error,

ImproperlyConfigured: The SECRET_KEY setting must not be empty.

Answer 1

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')
