Question

我创建了一个电子商务项目的product_view页面，我正在尝试访问页面上的一些项目及其详细信息。页面加载时，我只是项目图像的名称而不是图像本身。以下是截图：

这是我的settings.py

未经查看settings.py或urls.py ...可能是错误发生在template.html。

要显示图片，您需要使用<img>标记，如下所示：

<img src="{{ item.image.url }}">

即使路径不正确，也不应该在页面上显示，因为它是img标记内的参数。好像你忘了把它放在这个标签里......

编辑：既然你用模板代码更新了你的问题，那确实是这样的。
