我是否可以在Django中的模型删除方法中获取当前用户(通过该方法删除适当的m2m )？

def delete_model(self, request=None):
    if request:
        user = request.user
        # 根据需要进行其他操作
    super().delete()

current_user = None

def my_view(request):
    global current_user
    current_user = request.user
    # 调用模型删除方法

def delete_model(self):
    if current_user:
        user = current_user
        # 根据需要进行其他操作
    super().delete()

from django.db.models.signals import pre_delete
from django.dispatch import receiver

@receiver(pre_delete, sender=YourModel)
def delete_model(sender, instance, **kwargs):
    user = instance._request_user
    # 根据需要进行其他操作

class YourModel(models.Model):
    # 模型字段定义

    _request_user = models.ForeignKey(User, on_delete=models.CASCADE)
