在Django中跟踪对所有模型的更改

from django.db.models.signals import post_save, post_delete
from django.dispatch import receiver
from django.contrib.contenttypes.models import ContentType

@receiver(post_save)
@receiver(post_delete)
def track_model_changes(sender, **kwargs):
    # 处理模型更改事件的逻辑
    pass

@receiver(post_save)
@receiver(post_delete)
def track_model_changes(sender, **kwargs):
    model_name = sender.__name__  # 获取模型名称
    change_type = "保存" if kwargs.get('created') else "删除"  # 判断更改类型
    # 处理模型更改事件的逻辑
    pass
