解决方案

您是Deleteview从 a继承的DetailView，而不是 a DeleteView，因此出现错误：

from django.views.generic import DeleteView

class Deleteview(DeleteView):
    model = Task
    template_name = 'delete.html'
    success_url = reverse_lazy('todoapp:home')

然而，我强烈建议不要给你的视图命名Deleteview，因为它很容易与 Django 内置的基于类的视图混淆。通常模型是在名称中指定的，所以TaskDeleteView不是Deleteview：

class TaskDeleteView(DeleteView):
    model = Task
    template_name = 'delete.html'
    success_url = reverse_lazy('todoapp:home')
