Django project doesn't work when setting project root url to not "/"

I had a Django project (using Django, uwsgi and Nginx to deploy it) on a linux server that works well when I'm setting the project root url in Nginx as

    location / {
        uwsgi_pass  django;
        include     /path/to/project/uwsgi_params;
    }

So the project can be accessed using url like: www.mysite.com

However, I'm planing build more web projects on this server, and want to visit them using different urls like: www.mysite.com/oldproject www.mysite.com/project2```

So I changed my now existing project's Nginx conf file as:

    location /oldproject {
        uwsgi_pass  django;
        include     /path/to/project/uwsgi_params; 
    }

however, when I visit the old project using www.mysite.com/oldproject I get feed back like: Not Found. cant get resource on the server

I'm pretty sure that the Nginx is working well with uwsgi because I did some simple test, so, what is going wrong?

The full configuration is shown below:

Nginx conf:

# mysite_nginx.conf

# the upstream component nginx needs to connect to
upstream django {
    server unix:///web/welib/welib.sock; # for a file socket
}

# configuration of the server
server {

    listen       443 ssl;
    ssl_certificate /etc/nginx/certif/1_www.xxxxxxx.crt;
    ssl_certificate_key /etc/nginx/certif/2_www.xxxxx.key;
    ssl_session_timeout 5m;
    ssl_ciphers ECDHE8-GCM-SHA256:ES:HIGH:!NULL:!aNULL:!MD5:!ADH:!RC4;
    ssl_protocols TLSv1 TLSv1.1 TLSv1.2;
    ssl_prefer_server_ciphers on;  

    charset     utf-8;

    # max upload size
    client_max_body_size 75M;   # adjust to taste

    #log config
    access_log      /path/to/project/log/access/nginx_access.log;
    error_log       /path/to/project/error/nginx_error.log;




    location /oldproject/static {
        alias /path/to/project/static/; 
    }

    location /oldproject {
        uwsgi_pass  django;
        include     /path/to/project/uwsgi_params; 
    }

}

uwsgi conf:

[uwsgi]

#used socket
#socket = 127.0.0.1:9090

Solution

You should add prefix '/oldproject' to the Django urls patterns.

urlpatterns = [path(r'^oldproject/', include(urlpatterns))]

from django.conf import settings

if settings.BASE_URL_PREFIX:
    urlpatterns = [path(settings.BASE_URL_PREFIX, include(urlpatterns))]

if you want to configure prefix
