Django如何向群中添加或删除用户发送信号？

from django.contrib.auth.models import User
from django.db.models.signals import post_save, pre_delete
from django.dispatch import receiver

@receiver(post_save, sender=User)
def add_user_to_group(sender, instance, created, **kwargs):
    if created:
        # 在这里执行添加用户到群组的操作
        pass

@receiver(pre_delete, sender=User)
def remove_user_from_group(sender, instance, **kwargs):
    # 在这里执行从群组中删除用户的操作
    pass

from django.apps import AppConfig

class YourAppConfig(AppConfig):
    default_auto_field = 'django.db.models.BigAutoField'
    name = 'your_app_name'

    def ready(self):
        import your_app_name.signals

default_app_config = 'your_app_name.apps.YourAppConfig'
