Ich habe meinen DB aus einer falschen Sicherungsdatei wiederhergestellt, in der die Tabelle, die ich benötigte, nicht ex ⇐ Python

[Anonymous]

Ich hatte eine Blog -Tabelle in meinem DB, habe aber versehentlich eine falsche Backup.sql -Datei wiederhergestellt, damit sie verschwand. Ich habe momentan nicht in der Blog_user-Tabelle in DB, aber ich habe ein Migrations-Erstellungsbenutzermodell.

Code: Select all

python manage.py migrate blog zero
< /code>
oder < /p>
python manage.py migrate blog zero --fake
< /code>
, aber Fehler erhalten: < /p>

Ich dachte, das [url=viewtopic.php?t=26065]Problem[/url] könnte sein, dass das Benutzermodell irgendwo in Kleinbuchstaben und in Großbuchstaben woanders definiert ist. Es gibt also einen Konflikt, aber nein, es ist das gleiche Großbuchstaben.class Post(models.Model):
title = models.CharField(max_length=255)
# body = models.TextField()
body = RichTextUploadingField(blank=True, null=True)
created = models.DateTimeField(auto_now_add=True)
updated = models.DateTimeField(auto_now=True)
author = models.ForeignKey(settings.AUTH_USER_MODEL, on_delete=models.CASCADE)
slug = models.SlugField(max_length=1000, null=True, blank=True)
tags = TaggableManager(blank=True)
read_later_users = models.ManyToManyField(get_user_model(), related_name='read_later_posts')
preview_image = models.ImageField(upload_to=get_file_path_preview_images, null=True, blank=True)
class Meta:
ordering = ["created"]

def __str__(self):
return self.title

def get_absolute_url(self):
return reverse("blog:post_detail", args=[self.id])

class User(AbstractUser):
pass

p.s.: Wenn es erforderlich ist, um einen anderen Code zu geben, Kommentar und ich füge ihn hinzu.
