有时我们需要逻辑删除一个或多个数据，我们需要再modle模型中添加is_delete字段表示是否逻辑删除，新增视图时在继承CustomModelViewSet并且重写destroy方法如下即可：

from utils.serializers import CustomModelSerializer
from utils.viewset import CustomModelViewSet
from utils.modles import CoreModel

class User(CoreModel):
    account = models.CharField(max_length=30, unique=True, verbose_name='登录账户', help_text='登录账户')  # 必填,唯一
    password = models.CharField(max_length=100, null=True, blank=True,verbose_name='登录密码', help_text='登录密码')  # 非必填,默认888888(已加密)
    username = models.CharField(max_length=30, verbose_name='用户名称', help_text='用户名称')  # 改为必填
    phone_number = models.CharField(max_length=11, null=True, blank=True, verbose_name='手机号码', help_text='手机号码')  # 非必填
    is_delete = models.BooleanField(default=False, blank=True, verbose_name='逻辑删除', help_text='逻辑删除')  # 非必填

class UserManageSerializer(CustomModelSerializer):
    """
    用户管理-序列化器
    """

    class Meta:
        model = Users
        read_only_fields = ["id"]
        exclude = ['password']
        extra_kwargs = {
            'post': {'required': False},
        }

class UserManageViewSet(CustomModelViewSet):
    """
    后台用户管理 接口:
    """
    queryset = Users.objects.exclude(is_superuser=True).exclude(role__admin=True).exclude(role__isnull=False).all().order_by("-create_datetime")#排除管理员
    serializer_class = UserManageSerializer
    filter_class = UsersManageTimeFilter
    
    #重写delete方法，让它支持批量删除 如：  /api/admin/user/1,2,3/ 批量删除id 1，2，3得用户
    #重写delete方法，并改为逻辑删除
    def destroy(self, request, *args, **kwargs):
        instance = self.get_object_list()
        for i in range(len(instance)):
            randomstr = getRandomSet(4)
            instance[i].is_delete = True
            instance[i].username = instance[i].username +"(已删除)"+randomstr
            instance[i].mobile = instance[i].mobile + "(已删除)" + randomstr
            instance[i].save()
        return SuccessResponse(data=[], msg="删除成功")

高性能批量更新（删除）操作(bulk_update)

    #重写delete方法，并改为逻辑删除
    def destroy(self, request, *args, **kwargs):
        instance = self.get_object_list()
        for i in range(len(instance)):
            randomstr = getRandomSet(4)
            instance[i].is_delete = True
            instance[i].username = instance[i].username +"(已删除)"+randomstr
            instance[i].mobile = instance[i].mobile + "(已删除)" + randomstr
        #Users.objects.bulk_update(instance,fields=['is_delete','username','mobile'])
        model = self.get_serializer().Meta.model
        model.objects.bulk_update(instance,fields=['is_delete','username','mobile'])
        return SuccessResponse(data=[], msg="删除成功")
