Django AppRegistryNotReady beim Definieren eines Modells

Question

Ich wollte das erste Modell zu einer bereits funktionierenden App hinzufügen, und jetzt kann ich es nicht starten, weil es immer AppRegistryNotReady gibt. Dies passiert nur, wenn mein Modell MailLog ein Kind von models.Model ist.

from __future__ import unicode_literals 
from django.db import models 

#class MailLog(models.Model): # like this, it crashes 
class MailLog(): # like this, it works 
    # Field definitions 
    recipient = models.EmailField() 
    created = models.DateTimeField(auto_now_add=True) 
    template = models.CharField(max_length=500) 
    error = models.TextField(null=True) 

    def __str__(self): 
     return self.recipient+" "+self.template+"("+str(self.created)+")" 

Der Fehler tritt auf, egal was in der Klasse ist, auch wenn es nur ein pass ist. Ich kann jedoch meine Modelle in admin.py importieren und stürzt ab, wenn ich aus einer Datei namens core.py importiere. Diese Datei sieht wie folgt aus:.

import boto3 
from botocore.exceptions import ClientError 
from django.template import loader 
from django.conf import settings 
from .templates import * 
from .models import MailLog

wie folgt aussieht sollten Sie nicht Django Modelle in Ihrer App __init__ (oder was sie von core durch den Import importiert werden werden Import Wenn Sie Verwenden Sie eine leere __init__.py
