Django Admin应用程序的内容未显示

标签： python django

由于某种原因，包含list of all the Projects的数据库的内容由于某种原因未显示在我的Projects/Issues page上。

我最近在我的软件中添加了一个功能，使它每次点击Issues page中的保存时都会向管理员和相关人员发送电子邮件。自从我添加了该功能以来，我的网站停止显示内容，但是显示列表中的内容数量。

更新 Project page上的第一个条目没有显示。表格标题也不会显示。但是，当我添加第二个条目时，会显示第二个条目，但第一个没有。我正在使用SQLite。不适用于MySQL生产。 在我的Issues/Bugs table中，没有显示任何条目，也没有显示表格的标题。这意味着，我无法删除条目或对到目前为止所做的全部更改。 有人可以帮我吗？ 这是我的Models.py
