Super einfach Tutorial werfen django.core.exceptions.AppRegistryNotReady: Apps sind noch nicht geladen

Question

Ich habe eine einfache Django Web App erstellt. Wenn ich die models.py-Datei ausführe, erhalte ich den folgenden Fehler. Ich habe eine Reihe von Lösungen ausprobiert, darunter das Entfernen meiner Apps nacheinander, das erneute Installieren von django (ich habe Version 2.0), einen alten Systemneustart, Einfügen von import django + django.setup(), das Aktualisieren des virtualenv.

Traceback (most recent call last): 
File "C:/Users/Pritee/djangogirls/blog/models.py", line 6, in <module> 
class Post(models.Model):

Mein Repo ist here: (es etwas anders Namensgebung hat, da ich das Tutorial versuchte es noch einmal von Grund auf zu tun, um zu sehen, ob ich es beheben könnte)

Answer 1

Ich glaube, du hast Post eine Vertiefung Fehler in Zeile 6 der Klasse. Verwenden Sie einfach einen Tab vor dem Veröffentlichungsdatum.

Versuchen Sie dies in Ihrem models.py

class Post(models.Model): 
    author = models.ForeignKey('auth.User',on_delete=models.CASCADE) 
    title = models.CharField(max_length=200) 
    text = models.TextField() 
    created_date = models.DateTimeField(default=timezone.now) 
    published_date = models.DateTimeField(blank=True, null=True)
