Question

我一直在关注YouTube教程，尽管我完全按照他的说法进行操作，但我在下面收到404错误。我也没有运气从模型中获取数据到我的模板中。即使模板加载，它也只是空白。（我也可以上传这个例子）它加载静态内容但不加载数据库中的动态内容。谁知道为什么会这样？我猜它可能是我的settings.py中的东西？谢谢！

Page not found (404)

Answer 1

您将转到浏览器中的网址"/band/"，但尚未为该网址定义网址模式：您已定义"/"和"/band/<id>/"。转到根页面，或找到现有band对象的ID并转到该页面。

你几乎肯定会更好地做正式的Django教程，而不是随机播放YouTube视频。
