問題描述

提出一個問題，也順便記錄一下~，因為涉及到的文件比較多，所以只貼部分代碼：下面是views文件：

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:
