python - 无法在 Django 中调试或使用 pdb : bdb. BdbQuit

Question

我正在使用 Django (2, 2, 4, 'final', 0)在 docker 中，但我可以在里面猛击以打开或执行所需的任何内容。但是我不能调试。 ( How to debug in Django, the good way? 陈述了一些方法，没有对我有用)

在我的 views.py 内我有各种功能，例如这里的这个。

def visGraph(request):
    showgraph = 'Graphen'
    selectDB = request.GET.get('selectDB', '')
    __import__("pdb").set_trace()
    title += " <i>"+showgraph+"</i> ("+selectDB+")"

它工作正常，直到我填写 pdb，添加调试器使我的应用程序立即崩溃:

> /code/DjangoGraphen/views.py(74)visGraph()
-> title += " <i>"+showgraph+"</i> ("+selectDB+")"
(Pdb)

    if self.quitting: raise BdbQuit

如果我使用 __import__("pdb").set_trace() 没有太大关系或 breakpoint() - 两者都返回相同的结果。
到目前为止，在我的 settings.py 中，我有 DEBUG = True ，将其设置为 False不会改变任何东西。

我正在使用以下命令在命令行中查看日志:

docker logs django_web_1 -f

我假设对于 pdb，我需要一个事件的 shell 而不仅仅是一个日志查看器，但我不知道要更改什么或如何做。
但是已经尝试过这里给出的答案: Interactive shell in Django
但它只是打开了一个 Python-Shell。

解决方案实际上相当简单。问题是 docker 。解决方案在此处说明并且有效:
https://medium.com/@vladyslav.krylasov/how-to-use-pdb-inside-a-docker-container-eeb230de4d11

将此添加到您的 docker-compose.yml 中:

 ports:
      - "4444:4444"
    stdin_open: true
    tty: true

安装 remote-pdb并使用您的默认 pdb 命令代替:

__import__("remote_pdb").set_trace(host='0.0.0.0', port=4444)

登录您的 docker 并 telnet 进入 pdb session :

telnet 0.0.0.0 4444
