所以我在我的Django项目中创建了几个应用程序，我有一个名为main_app的主要应用程序.
其他应用程序被称为配置文件应用程序、设置应用程序、消息应用程序.
The issue:
我遇到的问题是，每当我try 使用应用程序名称空间和URL名称(例如，profilepage_app:"配置文件-重定向")从main_app中的配置文件_应用程序运行特定的查看函数时，我收到一个404错误，指出"Page Not Found".
I have done the following:
- 注册所有应用程序.
- 已在我的设置URL中链接urls.py文件.
- 我试图在main_app内创建一个测试视图函数，它可以很好地工作，但同样的函数不能在profile_app中工作.
- 创建了另一个测试应用程序，以查看我是否仍然存在相同的问题(我确实有).
所以问题是，我试图在浏览器中显示的所有应用程序(Main_app除外)的任何链接都会生成"Page Not Found"-错误.
My questions:
- 这一切为什么要发生？
- 我如何解决此问题？
- 这与我的设置文件有关吗？
The error:
