Question

嘿，抱歉，打扰您了，我是django的新手，我制作了个人档案，并且在本地所有内容都很完美，但是部署的那个不会加载我在实时应用程序中上传的图像。

我试图在这里看到youtube视频很多话题，但找不到解决方法...：（

这里是我的代码：

不鼓励开发人员自己使用django在实时服务器和产品中提供媒体和静态文件，只有在调试模式下才应使用。

关于您的错误，您是否尝试访问/media/portfolio/images/uploaded_image并查看它是否显示上传的图片？

还要验证静态文件夹my_app/static/my_app/example.jpg的路径

该文档可能会帮助您：https://docs.djangoproject.com/en/2.2/howto/static-files/

我在实时服务器上上传时，媒体文件夹中的静态文件未显示
