如何强制Django使用多重继承删除对象

from django.db import models

class CustomModel(models.Model, OtherParentClass):
    # 添加自定义字段和方法
    pass

class MyModel(CustomModel):
    # 添加模型字段和方法
    pass

def delete_object(request, object_id):
    try:
        obj = MyModel.objects.get(id=object_id)
        obj.delete()
        # 执行其他操作或返回响应
    except MyModel.DoesNotExist:
        # 处理对象不存在的情况
        pass
