我有一个运行一些长时间运行任务的应用程序，我正在显示用户在特定页面上进行的运行日志(表格(。页面上的表格中有一个结果位置，我希望它是一个超链接，单击后，会被重定向到用户可以查看结果的页面。
我收到一个：
NoReverseMatch: Reverse for 'past_run_results' with arguments '(u'1649103c-67d0-47f9-a085-401c02acff6a',)' not found. 1 pattern(s) tried: ['discovery-engine/past-runs/(P<task_id>[-\w]+)$']
我无法弄清楚出了什么问题

task_id是唯一的键，例如1649103c-67d0-47f9-a085-401c02acff6a。 Django版本是1.11的，python版本是2.7
您在(?P<task_id>[-w]+)中缺少问号。
