Tanya soalan dan rekodkan dengan cara~ Kerana terdapat banyak fail yang terlibat, saya hanya menyiarkan sebahagian daripada kod:
Berikut ialah fail pandangan:

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.

Anda boleh melaksanakan kod Python sewenang-wenangnya dalam bingkai tindanan dan terdapat beberapa pembantu tambahan yang tersedia untuk introspeksi:
