Django3.0: Images from database not showing-up after debug=False

Question

After debug=False in my settings. Images from database not showing up otherwise they were. Static files are showing up real good. Even my media files were showing up before debug=False. Database has correct addresses of files but covers not showing up.

Following is the code, how I am accessing cover images.

<div class="product-top">
     <img src="{{ product.cover.url }}" alt="book-image">
     <h5>{{ product.title }}</h5>
</div>

my settings.py related code:

as my terminal says after debug=true:

Answer 1

It is worth noting that django itself does not serve static and media files when debug is false.You should use a reverse proxy like ha proxy or nginx if you are in production otherwise set debug to true for local development Below is an example for nginx server block that serves your application, static and media files.

server {
    server_name your_server_ip;
    proxy_read_timeout 600s;
    client_max_body_size 25M;

    location /static {
            alias /home/trello/static/;
    }


    location /media {
            alias /home/trello/media/;
    }


    location / {
    proxy_pass http://127.0.0.1:8000;
    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    proxy_set_header Host $http_host;
    proxy_set_header X-Real-IP $remote_addr;
    proxy_redirect off;
    }
