【问题描述】:
由于某种原因,我无法查看带有没有连字符的 slug 的页面。例如:
这不起作用: /示例1
这有效: /这种方式有效
我尝试过更改正则表达式,但没有任何乐趣。任何帮助,将不胜感激!

【问题讨论】:
-
在你的正则表达式末尾有一个
/。你试过/example1/吗?当您说“它不起作用”时,发生了什么?你有错误信息吗? -
嗨,是的,最后有一个 /。我收到错误消息页面未找到 404。没有用户匹配给定的查询。
-
因为您的示例与任何结果都不匹配,并且您使用
get_object_or_404这就是为什么它会引发Http404错误 -
但是当我有一个带有连字符的网址时它可以工作。我不明白带连字符的链接是如何工作的,但是没有连字符的单个单词就不起作用?
-
你的正则表达式看起来不错
