Django NoReverseMatch in reverse（）调用

我又花了一个晚上在这上面。。。有人能帮忙吗

我正在尝试复制kickstart示例，该示例似乎是为Django的早期版本开发的（并且没有全面描述操作方法）

无论如何，我管理任务直到“将任务标记为完成”。然后我的问题开始了

很清楚，在我将“mark_done”添加到ItemAdmin类的list_display属性之前，一切都很好。然后它似乎无法解决trc.todo.views.mark_done 我尝试了完整的、绝对的模块参考，以及您在下面看到的部分模块参考，但都没有成功。 我更喜欢局部的（以“todo”开头），因为它意味着易于移植到其他项目

谢谢你的帮助

我有一个文件树，如下所示：

truc/ (my project)
|-todo/ (my app)
| |-__init__.py
| |-views.py
| |-urls.py  (module urls)
| |-models.py
| |-templates/admin/todo/item/change_list.html
|-truc/
| |-urls.py  (main urls)
| |-settings.py
| |-etc.

我的主要URL包含： 我的模块URL包含： 在models.py中，我有： 来自django.db导入模型的

从django.contrib.auth.models导入用户
从django.contrib导入管理
从django.utils.translation导入ugettext作为_
从django.utils.encoding导入强制_文本
从django.http导入Http404、HttpResponse、HttpResponseRedirect
从django.core.urlResolver反向导入
