问题描述
我目前正在使用python开发烧瓶，到目前为止，我还没有问题，但是现在我有一个问题，无法访问更新/删除帖子页面。
登录帐户后，我的帖子应该看起来像这样，以便我可以更新或删除帖子。我的编码没有错误。
但是，我的现在看起来像这样。
下面的链接是我正在制作的视频。

起初，我以为可能是打字问题，所以我从他的github数据中复制并粘贴了所有内容。 但是，我仍然无法访问我的网站上的那些页面。另外，我也仔细检查了文件位置。
https://github.com/CoreyMSchafer/code_snippets/tree/master/Python/Flask_Blog/11-Blueprints
即使我每次通过python run.py命令激活flaskblog文件时，都会在终端上收到警告，但我认为这与问题无关。
py:834: FSADeprecationWarning: sqlALCHEMY_TRACK_MODIFICATIONS adds significant overhead and will be disabled by default in the future. Set it to True or False to suppress this warning.

解决方法
这是我愚蠢的错误。我没有以该帖子的用户身份登录。
