运行 Django 单元测试时关系不存在

Question

当我的 django 应用程序通过 Jenkins 运行时，我在运行单元测试时遇到问题。

我有一个运行

python manage.py test

的 CI/CD 管道，目前失败并出现以下错误：

django.db.utils.ProgrammingError: relation "auth_user" does not exist

.

在本地运行测试工作正常，测试数据库正常创建并且测试正常运行。

我通过 SSH 连接到设置 Jenkins 的服务器来尝试手动运行测试，但我得到了相同的结果，所以我不会说这是 Jenkins 特有的任何内容。

postgres 用户拥有数据库上的所有权限和 CREATEDB，因此 postgres 方面似乎一切都很好。

这是完全的例外：

Traceback (most recent call last):
  File "/home/agent/jenkins/workspace/INP-Backend/venv/lib/python3.9/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:

Answer 1

我已经解决了这个问题。在 @djvg 提到没有迁移的模型之后，我进行了更深入的研究。结果发现应用程序没有自动迁移，必须为其运行手动迁移。

我仍然不知道为什么这会完全停止测试，因为该应用程序不依赖于其他应用程序，并且没有在测试用例中使用，但迁移该应用程序专门解决了我的问题。
