“No such column” nach dem Hinzufügen eines Feldes zum Modell
environment DJANGO VERSION 1.9 Python 2.7.6
Ich habe einer Modellklasse in models.py ein Feld (Punkte) hinzugefügt.
from django.db import models
from django.contrib.auth.models import User
import urllib
import hashlib
class profile(models.Model):
user = models.OneToOneField(User)
nickname = models.CharField(max_length=12, blank=True, null=True)
use_gravatar = models.BooleanField(default=True)
location = models.CharField(max_length=20, blank=True, null=True)
avatar_url = models.URLField(blank=True, null=True)
website = models.URLField(blank=True, null=True)
**scores = models.IntegerField(default = 0)**
und ich führe die folgenden Befehle aus, um die Datenbank zu synchronisieren.
python manage.py makemigrations
python manage.py migrate
Aber ich habe dieses
