[英]Reverse for 'post_detail' with arguments '('',)' not found. 1 pattern(s) tried: ['post/(?P<slug>[-\\w]+)/$']
使用 Django 1.11 | 出现这个问题，我以为是因为我从另一个项目中复制了一些网址和视图，但即使删除后，问题还是再次出现。 我只是想删除我的 PostImg 字段并将图像字段添加为 FileField，但是即使在删除数据库和所有迁移等之后也没有 postImg 字段的问题。这个问题只发生在我没有帖子（不是对象模型 Post) 在我的数据库中。 我可以登录管理员没问题，然后创建一个帖子，然后它就可以工作了。 我认为这是因为我'，显示所有带有模板标签的帖子，如果没有对象，这些标签就无法处理它。
注意：我在添加 slug 时遇到了麻烦，但我找到了一个很好的方法（我不会有任何重复的博客标题）。 但是，这个问题甚至在我添加 slug 之前就发生了。

如果我遗漏了任何文件，请告诉我，否则，非常感谢您的帮助
我找到了答案。 所以通常，我总是使用 for 循环来遍历模板中 post_list 中的所有帖子。 这适用于{% for post in post_list %}因为它只在有对象时迭代。 因此，我将最新的帖子放在顶部，而不是在 for 循环中，模板中的 with 语句： {% with post_list|first as post %}尝试运行，尽管帖子列表中没有对象。 因此，我只需要在post_list中添加一个检查是否有任何帖子，因此home.html中的代码变为：
{% extends 'blog/base.html' %}

只需在 with 块周围添加一个检查 {% if post_list %} 以确保它仅在我在数据库中有帖子要显示时运行。 我希望这对其他人有帮助。
