Django-Modul-Objekt ist nicht iterierbar

Question

Ich versuche derzeit, einen Blog mit Django zu bauen. Ich habe diesen Fehler nun seit ein paar Stunden erlebt. Ich bin mir nicht ganz sicher, ob das etwas mit den Verzeichnissen zu tun hat, aber der Fehler tritt auf, wenn ich versuche, mein Modell in der Datei admin.py zu registrieren.

from django.contrib import admin 
from .models import Post 

# Register models 
admin.site.register(Post) 

die Verzeichnisse wie folgt aussehen:

blog 
    models 
     Post 
     Category 
    admin.py 
settings 
static 
templates

Der Fehler passiert hier: https://github.com/django/django/blob/master/django/contrib/admin/sites.py#L100-L101

Immer, wenn ich die Registerlinie alles funktioniert kommentieren.

Answer 1

Anstatt "von .models Import Post" zu schreiben, sollten Sie "from .models.Post import Post" schreiben.

Erster "Post" ist ein Modulname (Dateiname), zweiter ist ein Klassenname.
