Include user in the signal kwargs

[martini97]

Describe the problem

Hi, is there a way to include the admin user in the kwargs of the config_updated signal? I understand that it's possible to update from the command line (it would be nice to have a flag blocking this as well), but when changed from the admin page it would be nice to have this info to allow for accountability.

here is my code， its work：

yourapp/middleware.py

# yourapp/middleware.py
import threading

_thread_locals = threading.local()

class CurrentUserMiddleware:
    def __init__(self, get_response):
        self.get_response = get_response
        
    def __call__(self, request):
        # save the user
        _thread_locals.user = request.user if hasattr(request, 'user') else None
        response = self.get_response(request)
        # clear
        _thread_locals.user = None
        return response

def get_current_user():
    return getattr(_thread_locals, 'user', None)

settings.py

# settings.py
MIDDLEWARE += [
    'yourapp.middleware.CurrentUserMiddleware',
    # ...
]

yourapp/signals.py

# yourapp/signals.py
from django.dispatch import receiver
from constance.signals import config_updated
from .middleware import get_current_user

@receiver(config_updated)
def constance_updated(sender, key, old_value, new_value, **kwargs):
    user = get_current_user()
    username = user.username if user and user.is_authenticated else '未知用户'
    print(f"用户 '{username}' 将配置项 '{key}' 从 '{old_value}' 修改为 '{new_value}'")

yourapp/apps.py

# yourapp/apps.py
from django.apps import AppConfig


class ConfigManagerConfig(AppConfig):
    default_auto_field = 'django.db.models.BigAutoField'
    name = 'yourapp'


    def ready(self):
        import yourapp.signals
