Django Admin + FORCE_SCRIPT_NAME + Login redirects incorrectly

Question

I've got Django running behind Nginx with fastcgi_pass. I run Django at a subpath like /django/sample.

location /django/sample {
    include fastcgi_params;
    fastcgi_pass 127.0.0.1:8025;
}

I use FORCE_SCRIPT_NAME in the Django settings module, which seems to fix all the issues I was having in regards to it running at a subpath.

In settings.py:

FORCE_SCRIPT_NAME = "/django/sample/"

I go here to login with admin (and correctly get the admin UI):

http://server/django/sample/admin

But when I submit, it redirects to:

http://server/django/sample/django/sample/admin

What's really strange is that if I change FORCE_SCRIPT_NAME="" the login works.

BUT, then all of the links in the admin page are /admin, not /django/sample/admin/

What the heck am I missing? Setting FORCE_SCRIPT_NAME="/django/sample/" seems to fix everything except admin login.

Any ideas?

UPDATE:

I've also tried using fastcgi_split_path_info in nginx conf (and take out FORCE_SCRIPT_NAME in settings). Again, that fixes all the path issues except the admin login redirect.

conf like this:

location /django/sample {
    fastcgi_split_path_info ^(/django/sample)(.*)$;
    include fastcgi_params;
    fastcgi_pass 127.0.0.1:8025;
}

FYI, I gave up. All the documentation says it's supposed to be easy. But it's too much of a pain to deal with. I instead am requiring our Django apps to use a subdomain and setup a vhost with the server. This way Django can run at document root "/"

FWIW, I've written up a solution in another thread that's worked for me when I have a proxy server in front of a Django server using wsgi.

As I remember troubleshooting this a long time ago... you saw the out-of-sync behavior because of the way the Django admin sets up and processes the next param on the form submit.

Based on my experience, Django sites should definitely use FORCE_SCRIPT_NAME to modify the way your backend generates links, and your proxy server should also strip out the subfolder (i.e. script-name) part of the path.
