Unverständlicher Django Runserver Fehler

Question

Ich hatte schon viele Probleme mit Django (nicht alle wurden gelöst), aber dieses ist bei weitem das seltsamste und unverständlichste. Es passiert, wenn ich eine Seite lade:

\>python manage.py runserver

Validating models...

0 errors found
Django version 1.3.1, using settings 'ponysite.settings'
Development server is running at http://127.0.0.1:8000/
Quit the server with CTRL-BREAK.

Ich habe versucht, die Datenbank zu löschen und neu zu erstellen, die views.py y models.py auf das absolute Minimum reduziert, ohne Erfolg. Ich habe auch versucht, dasselbe Projekt auf einem anderen Computer auszuführen - mit demselben Ergebnis. Auf beiden läuft Windows x64. Eigentlich denke ich, der eine Computer läuft Django 1.3.x und der ther 1.2.x, aber der Fehler sieht das gleiche unabhängig davon.

Hier ist der vollständige Traceback:

Exception Type: ImportError at /
Exception Value: cannot import name Ban

Ban war ein Modell in models.py (importiert in views.py ) Ich spielte herum mit für eine Weile, aber es ist derzeit überall in meinem Modell, Ansicht und Controller auskommentiert. Ich weiß nicht, ob es überhaupt etwas mit dem Problem zu tun hat.

Vielen Dank im Voraus, Leute.

Answer 1

Basierend auf dieser Zeile:

File "C:\Users\kiwi\Dropbox\Programming Projects\Django Projects\ponysite\forum\admin.py" in
1. from forum.models  import Category, Thread, Post, Report, Subscription, Ban

Django findet in forum/admin.py

from forum.models  import Category, Thread, Post, Report, Subscription, Ban

Beachten Sie die Ban am Ende, die nicht in Modellen definiert ist. Entfernen Sie es und der Fehler sollte verschwunden sein.
