我可以帮助我，在我出错的地方或我需要的地方帮助我，我只是坚持这一点。最初，当我点击导航栏上的新帖子时，它工作正常，当我可以输入文字和作者时，它会引导我到表格，但现在当我点击那里时，我得到了这个NoReverseMatch at /post/new/ Reverse for 'post_publish' with keyword arguments '{'pk': ''}' not found。
谢谢。
答案 0 :(得分：0)
我的第一个猜测是post对象在这里为null：
<a class = 'btn btn-primary' href=" {% url 'post_publish' pk=post.pk
%}">Publish</a>
但是要确保我们需要一个完整的堆栈。

我们仍然缺少追溯，我无法在你的照片中看到它，但我的答案仍然有效。 post.pk为None，你应该用object.pk替换它，因为你正在使用Detailview。
