I am trying to configure a project for pythonanywhere.com.
I deleted an old sqlite3 file, as well as migrations, so now I want to restore it. I launched command py manage.py makemigrations, then I run py manage.py migrate. But there I got an error:
Operations to perform:
Apply all migrations: FriendsAnalyzer, account, admin, auth, contenttypes, sessions, sites, socialaccount
Running migrations:
Applying socialaccount.0001_initial...Traceback (most recent call last):

I don't think that the problem is in models.py because it worked well on my local computer. But here it is:
from django.db import models
from allauth.socialaccount.models import SocialAccount
# Create your models here.
class ResultInfo(models.Model):
uid = models.ForeignKey(SocialAccount, on_delete=models.CASCADE)
friend_id = models.CharField(max_length = 16)
status = models.BooleanField()
status_description = models.CharField(max_length = 16, null=True, blank=True)
result_info = models.JSONField()
def __str__(self):
return str(self.uid) ", friend_id:" self.friend_id
class Meta:
constraints = [
models.UniqueConstraint(fields=['uid', 'friend_id'], name='composite_key')
]
I thought that the problem may be in lack of superuser, so I tried to create one. However, I got another problem: User Registration with error: no such table: auth_user. I read the solution here and it states that I need to do python manage.py migrate. But it is impossible, as I said previously.
This is a strange behavior because I still have no sqlite file. And exactly the same problem exists WITH sqlite file. Please note that it is NOT duplicate of this question because I have different traceback, also I have much newer version of Django (4.1), as well as the site works normally on localhost.
CodePudding user response：
You likely have a setting:
AUTH_USER_MODEL = 'auth.User'so with a capital U. This will refer to the user model.
You probably did not migrate the auth model. You can do this first with:
python manage.py migrate auth
