django - 没有找到带有关键字参数的 Django NoReverseMatch

问题描述

感谢您的帮助。长存储短，这是我的 git repo。https://github.com/nelsonyan/track 我在单击第 22 行的 href 时收到以下错误消息employee_list.html。它应该带我去employee_detail.html更新，但给了我关于track_deleteURL 标签的以下错误......这两个应用程序（报告，员工）有外键关联，但我不明白为什么员工应用程序的更新功能是相关的到报表应用的删除功能。任何 Django 专家可以帮助我吗？

GET 请求 URL： http: //127.0.0.1 :8000/employee/update/7/ Django 版本：2.0.5 异常类型：NoReverseMatch 异常值：

未找到带有关键字参数“{'pk': ''}' 的“track_delete”的反向操作。尝试了 1 种模式：['report\/delete\/(?P[0-9]+)\/$']

异常位置：C:\Users\Nelson\Anaconda3\envs\mydjangoenv\lib\site-packages\django\urls\resolvers.py 在 _reverse_with_prefix，第 632 行 Python 可执行文件：C:\Users\Nelson\Anaconda3\envs\mydjangoenv\ python.exe Python版本：3.6.6

具体来说，我正在尝试创建一个网站来跟踪艺术项目并显示公司员工信息。报告应用程序运行良好。它可以创建/显示/更新/删除报告记录。我只是将更新功能复制到员工应用程序，但有上述问题。可能是报表应用程序的模型有两个来自员工应用程序模型的同一类的外键（employeelist）。这就是这两个应用程序关联的原因，但我只是不知道如何在保持这种关系的同时解决这个问题。我是 Django 新手，欢迎任何建议。
谢谢
