Copy of django front with nginx?

Question

Nginx

Now there is a working project.
I need to redo the fronted a little, I want to raise the test version.
I copied the project folder and set up uwsgi.
The main project opens at:
my-ip.ru
What directive should be specified in etc/nginx/sites-available/conf so that the copy and the entire tree structure are opened when
visiting http:/my-ip.ru/ dev
And is this possible at all do?
I tried something like this, but I get a redirect to the main project

location /dev {
        rewrite /dev/(.+) /$1 break;
        include uwsgi_params;

        uwsgi_pass  127.0.0.1:9010;
        proxy_set_header    Host $host;
        proxy_set_header X-Real-IP $remote_addr;

    }

upd: There is no subdomain, and if on a different port, then the static is not loaded .....
