未找到参数为 '(1,)' 的 'new_entry' 反转尝试了 1 个模式：['new_entry/<int:post_id/$']

如何解决未找到参数为 '(1,)' 的 'new_entry' 反转尝试了 1 个模式：['new_entry/<int:post_id/$']

我目前正在编写“Python 速成课程”一书中的教程。本教程是关于使用 Django 创建“博客”Web 应用程序的。这个想法是在项目中创建一个名为 blogs 的应用程序和一个名为 BlogPost 的模型。模型应该有像 post、text 和 date_ added 这样的字段。为项目创建一个超级用户，并使用管理站点制作几个简短的帖子。制作一个按时间顺序显示所有帖子的主页。创建一个用于发布新帖子的表单和另一个用于编辑现有帖子的表单。填写您的表格以确保它们有效。

当我运行 http://127.0.0.1:8000/posts/1/

时，我目前无法编辑现有的条目表单并收到错误消息

我已经阅读了与我类似问题的答案，但他们提出的解决方案已经过审核，但仍然出现错误。我不理解为什么。如果有人能帮助我，我将不胜感激。
