Getting ProgrammingError: relation "auth_user" does not exist while running test

Question

最近我遇到了这个让我发疯的问题，但在互联网上没有找到任何解决方案。我不知道问题是什么时候产生的，或者我做了什么导致了这个问题，但现在每次我想运行在我的 Django 应用程序中进行测试时，都会出现这个错误：

Traceback (most recent call last):
  File "/home/mohammad/Projects/IP_Camera/venv/lib/python3.10/site-packages/django/db/backends/utils.py", line 89, in _execute
    return self.cursor.execute(sql, params)
psycopg2.errors.UndefinedTable: relation "auth_user" does not exist


The above exception was the direct cause of the following exception:

有人知道这里发生了什么吗？提前致谢。

参见问题。

This appears to happen with any inconsistency between your models and migration files when running unit tests.

确保您的应用中有 migrations/__init__.py 和 migrate。
