nginx,settings and url configs

If you're on linux this may help.

nginx file

your_machn:/#vim etc/nginx/sites-available/nginxfile

server {
    server_name xyz.com;

    location = /favicon.ico { access_log off; log_not_found off; }
    location /static/ {
        root /var/www/your_prj;
    }

    location /media/ {
        root /var/www/your_prj;
    }
...........
......
}

urls.py

.........
   .....
    urlpatterns = [
        path('admin/', admin.site.urls),
        path('test/', test_viewset.TestServer_View.as_view()),
        path('api/private/', include(router_admin.urls)),
        path('api/public/', include(router_public.urls)),    
        ]
    
    if settings.DEBUG:
        import debug_toolbar
        urlpatterns += static(settings.MEDIA_URL,document_root=settings.MEDIA_ROOT)
        urlpatterns += static(settings.STATIC_URL, document_root=settings.STATIC_ROOT)

settings.py

.....
........
STATIC_URL = '/static/'
MEDIA_URL = '/media/'

if DEBUG:
    STATIC_ROOT = '/var/www/your_prj/static/'
    MEDIA_ROOT = '/var/www/your_prj/media/'
else:
    STATIC_ROOT = os.path.join(BASE_DIR, 'static/')
    MEDIA_ROOT = os.path.join(BASE_DIR, 'media')
.....
