Django viewflow扩展任务视图

我正在尝试一个想法，在一个会有一些复杂权限规则的应用程序中同时使用和。我对django权限工作方式的理解是，向要应用权限规则的视图添加一个装饰器

通过扩展基本viewflow视图并将url.py指向扩展视图，我成功地在流程视图上实现了这一点。当我尝试在任务中遵循相同的想法时，我遇到了下面列出的错误

类型对象“CBVTask”没有属性“flow\u class”

型号.py

    created_by = models.ForeignKey(User)
    title = models.CharField(max_length=100)

提前感谢您的指点

这是一个新手犯的错误-url.py文件的内容应该如下所示：
