成功url在我的基于DeleteView的类中不起作用

from django.views.generic import DeleteView

class MyDeleteView(DeleteView):
    model = MyModel
    success_url = '/success-url/'

from django.urls import reverse_lazy
from django.views.generic import DeleteView

class MyDeleteView(DeleteView):
    model = MyModel
    success_url = reverse_lazy('success-url-name')

from django.urls import reverse_lazy
from django.views.generic import DeleteView

class MyDeleteView(DeleteView):
    model = MyModel
    success_url = reverse_lazy('success-url-name')

    def delete(self, request, *args, **kwargs):
        # 执行删除操作
        self.object = self.get_object()
        self.object.delete()
        return HttpResponseRedirect(self.get_success_url())
