Python, Debugger and Django

[Mte90]

I am trying to connect to my Django instance that run locally (on venv, no docker) with uv with the Debugger but Zed instead execute CodeLLDB.

this is my debug.json:

  {
    "label": "Django",
    "adapter": "Debugpy",
    "request": "attach",
    "tcp_connection": {
      "host": "127.0.0.1",
      "port": 5678
    },
    "cwd": "$ZED_WORKTREE_ROOT",
    "pathMappings": [
      {
        "localRoot": "${ZED_WORKTREE_ROOT}/",
        "remoteRoot": "/"
      }
    ],
    "justMyCode": true
  }
]

This is my manage.py:

"""Django's command-line utility for administrative tasks."""

import importlib.util
import os
import sys


def main():
    """Run administrative tasks."""
    os.environ.setdefault("DJANGO_SETTINGS_MODULE", "api.settings")
    if importlib.util.find_spec("debugpy") is not None:
        if os.environ.get("RUN_MAIN", "").lower() != "true":
            import debugpy
            debugpy.listen(("127.0.0.1", 5678))
            sys.stdout.write("Debug server started.\r\n")
    try:
        from django.core.management import execute_from_command_line
    except ImportError as exc:
        raise ImportError(
            "Couldn't import Django. Are you sure it's installed and "
            "available on your PYTHONPATH environment variable? Did you "
            "forget to activate a virtual environment?"
        ) from exc
    execute_from_command_line(sys.argv)


if __name__ == "__main__":
    main()

If I open with F4 the menu I have Attach and I pick the django process in the list, because I am executing Django in another terminal (not inside the editor).

Someone can help me understand what I am doing wrong?

For me below config is working for debugging python manage.py runserver

[
  {
    "adapter": "Debugpy",
    "label": "manger.py (Debugpy)",
    "request": "launch",
    "subProcess": true,
    "redirectOutput": true,
    "program": "manger.py",
    "args": ["runserver"],
    "stopOnEntry": false,
    "cwd": "<project_path>",
  },
]

but to achieve this you just installed debugpy? how?

[kuldeepdev4071]

I don't know but it was already available to me can you try below i think its just pip install debugpy

but the article doesn't mention Django, in my experience debugpy with DJango requires some workaround because spawn more processes and threads and debugpy needs to know what is the right one.
