这很有趣，因为我为另一个应用程序做了完全相同的事情，基本上只是复制和粘贴所有内容，只是稍微更改了模型。但这一个不想工作。
这是我收到的错误消息。

我很想了解这里发生了什么。我是 Django 新手，显然学习曲线比预期的要难得多。
【问题讨论】：
【参考方案1】：在您的网址中尝试将<slug:slug> 更改为<str:slug>
【讨论】：
【参考方案2】：尝试类似：
<a href="% url 'properties:detail' slug=property.slug %"> Edit </a>
【讨论】：
以上是关于未找到带有参数“（”，）”的“详细信息”的反向。尝试了 1 种模式：['users/(?P<username>[^/]+)/$']的主要内容，如果未能解决你的问题，请参考以下文章
未找到带有参数 '('',)' 的 'todo-user' 的反向操作。已尝试 1 种模式
未找到带有参数“()”和关键字参数“”的“password_change_done”的反向
