Question

我尝试更新实例并返回实例的Template视图。

问题：代码呈现编辑视图但是当我编辑实例并按保存时，它会返回此错误。我意识到错误告诉我，我的Identity_nest_list网址没有pk参数。但是我添加了它，它仍然给我错误。

基本上我希望能够编辑对象，保存编辑并将用户重定向到Identity_unique实例的更新版本，以及已经存在的其他实例

Answer 1

Identity_unique_Update的成功网址不包含pk：

success_url = reverse_lazy('Identity_nest_list')

将其更改为：

def get_success_url(self):
    return reverse('nesting:Identity_nest_list', kwargs={'pk': self.object.pk})

即使我的身份_发明列表＆＃39;出现NoReverseMatch错误统一资源定位符包含pk参数
