我已经花了一个晚上......有人可以帮忙吗？
我试图复制http://lightbird.net/dbe/todo_list.html的kickstart示例，这个示例似乎是为早期版本的Django开发的（并没有全面描述操作方法）
无论如何，我管理任务直到“将任务标记为已完成”。然后我的问题开始了。
要清楚，一切都很好，直到我将“mark_done”添加到ItemAdmin类的list_display属性中。然后它似乎无法解析truc.todo.views.mark_done 我已经尝试了完整的绝对模块参考，以及你在下面看到的部分参考，但无济于事。 我更喜欢部分的（从“todo”开始），因为它意味着易于移植到其他项目。
感谢您的帮助。
我有一个文件树，如下所示：

答案 0 :(得分：6)
这一行：
url(r'^todo/$', include('todo.urls'))
你不想要终止符号$，它阻止了包含工作。我不小心一直这样做。
答案 1 :(得分：2)
您需要为您的网址格式提供一个名称：
urlpatterns = patterns('todo.views',
url(r'^mark_done/(\d+)/$', 'mark_done', name='mark_done'),
)
并从“todo”模式中删除结束模式$，导致它停止：
urlpatterns = patterns('',
(r'^todo/', include('todo.urls')),
(r'^admin/doc/', include('django.contrib.admindocs.urls')),
(r'^admin/', include(admin.site.urls)),
)
然后你可以使用reverse，传入名称和参数：
def mark_done(self):
return "<a href='{0}'>Done</a>".format(reverse("mark_done", args=(self.pk,)))
mark_done.allow_tags = True
我假设你的代码示例中没有显示名为mark_done的视图函数。
