【问题描述】：
我在我的 Django 视图函数之一中有一个 try except 块，如果有任何事情失败，它将删除在 try 块中创建的用户对象。当我尝试删除用户时，我收到此错误消息。
OperationalError: no such table: reversion_revision
同样的问题也发生在 Django 管理员中。我在寻找其他人发生这种 OperationalError 的类似情况时遇到问题，并且不确定为什么会发生这种情况。我在除块中删除的所有其他对象都没有任何问题。

除了您提出的实际问题之外，我是否建议您使用transactions 来扭曲您的功能？它旨在准确处理您的情况，在发生错误时回滚更改。
