如何在Django模型中轻松地将记录标记为已删除而不是实际删除它们？

from django.db import models

class MyModel(models.Model):
    # ...
    is_deleted = models.BooleanField(default=False)
    # ...

from django.db.models import Q

class MyModelViewSet(viewsets.ModelViewSet):
    queryset = MyModel.objects.filter(Q(is_deleted=False))
    serializer_class = MyModelSerializer

class SoftDeleteManager(models.Manager):
    def get_queryset(self):
        return super().get_queryset().filter(is_deleted=False)

class MyModel(models.Model):
    # ...
    is_deleted = models.BooleanField(default=False)
    objects = SoftDeleteManager()
    all_objects = models.Manager()  # 用于获取所有记录，包括已删除的
    # ...

my_model_instance.is_deleted = True
my_model_instance.save()

my_model_instance.is_deleted = False
my_model_instance.save()
