The debugger caught an exception in your WSGI application. You can now look at the traceback which led to the error.
To switch between the interactive traceback and the plaintext one, you can click on the “Traceback” headline. From the text traceback you can also create a paste of it. For code execution mouse-over the frame you want to debug and click on the console icon on the right side.

You can execute arbitrary Python code in the stack frames and there are some extra helpers available for introspection:

dump() shows all variables in the frame
dump(obj) dumps all that’s known about the object

遇到了同样问题，怎么解决的？

Answer 2

已经解决。

原因：刷新前端页面前没有定义user的路由，登录、编辑和重设密码。

解决：前面跟学的时候，跟得比较紧，下面黄色框中的内容其实都还是空白。而老师讲课跳过了这个部分。先刷新了仪表盘，显示了前端页面。

  应该解决了哈，不懂的同学你看一下你的templates/commom下的文件有多少，应该是只有layout_main 和 layout_user 的，如果不是，就会导致索引出现问题，因为你复制的应该是完整的代码，但是课程代码不是这样的，课程代码中的html中对于currentname是由名曲的设定的，而不是调用，你如果用的是完整代码，那么你会发现你没有可以调用的名字，你需要登录，然后又没有设置登录接口
