Django3.0：debug = False

如何解决Django3.0：debug = False

在我的设置debug=False之后。来自数据库的图像未显示出来，否则显示出来。静态文件显示的很好。甚至我的媒体文件都出现在debug=False之前。数据库具有正确的文件地址，但没有显示出来。

以下是代码，我如何访问封面图像。

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

我的settings.py相关代码：

我的terminal在debug=false之后说：

[23/Aug/2020 23:07:00] "GET /media/covers/product1.PNG HTTP/1.1" 404 11974

我的terminal在debug=true之后说：

[23/Aug/2020 23:25:15] "GET /media/covers/product1.PNG HTTP/1.1" 200 103898

解决方法

值得注意的是，当debug为false时django本身不会提供静态文件和媒体文件，如果您正在生产中，则应使用ha代理或nginx之类的反向代理，否则将debug设置为true以进行本地开发 以下是为您的应用程序，静态文件和媒体文件提供服务的nginx服务器块的示例。

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;
    }
