我阅读了此处发布的类似解决方案：

https://intellij-support.jetbrains.com/hc/en-us/community/posts/360002753800-Django-console-not-working-properly-on-docker

我已经实现了上述解决方案。奇怪的是，我可以在PyCharm中打开Django控制台而不会出现错误。通过执行以下操作，我已经确认Django控制台正在Docker容器中运行：

>>> import socket
>>> socket.gethostname()
'f6f418ce5d14'

我有一个入口点脚本（bash脚本），该脚本在Docker容器内执行以下操作而没有错误：

python manage.py migrate
python manage.py loaddata --format json /srv/app/api/opp/management/fixtures/dev.json

但是，当PyCharm尝试执行测试用例时，使用PyCharm自己的鼻子测试运行器，即会出现错误。以下是使用Docker容器运行Django测试用例时PyCharm输出的摘录：

似乎是PyCharm提供的测试运行程序，这引起了问题。根据我看到的输出，我相信PyCharm测试运行程序在运行测试用例之前不会执行以下命令：

import django

django.setup()

我试图找到在Docker容器中运行的PyCharm测试，以便我可以手动对其进行编辑。但是，我找不到它。帮我Obi Wan Kanobi，您是我唯一的希望！
