Cannot run migration from Django on Docker to MariaDB installed on host - sql

Question

I created a Django project running on Docker, and I successfully connected from the container to the host MariaDB server as an URL host.docker.internal:3306 with the command sudo docker run -p 8000:8000 --add-host=host.docker.internal:host-gateway -d kms1212/jsis:latest. But due to several problems(I can't remember why I did it), I removed the original database, created a new database, and modified settings.py. Then I ran the modified Docker image that is built from Dockerfile:
FROM ubuntu:22.04
ENV PYTHONUNBUFFERED 1
RUN apt-get -y update
RUN apt-get -y install build-essential python-is-python3 pip mysql-client libmysqlclient-dev
RUN mkdir /usr/local/workdir
WORKDIR /usr/local/workdir
COPY requirements.txt .
RUN pip install --upgrade pip
RUN pip install -r requirements.txt
COPY jsis .
EXPOSE 8000
CMD ["bash", "-c", "python manage.py makemigrations && python manage.py showmigrations && python manage.py migrate && gunicorn --bind 0.0.0.0:8000 -k uvicorn.workers.UvicornWorker jsis.asgi:application"]
I dropped and recreated the database and checked that no old constraints and tables were left, but despite my effort, I got some error messages from the container log like this eventually:

(+ Edit)And this is model code:
class UserPermissions(models.IntegerChoices):
USER = 0
HQ = 1
TEACHER = 2
OTHER = 3
class UserAccountManager(BaseUserManager):
def create_user(self, username, email, visiblename, agreement_status, password=None):
if not email:
raise ValueError('Users must have an email address')
if not username:
raise ValueError('Users must have a username')
if not visiblename:
raise ValueError('Users must have a visible name')
user = self.model(
username=username,
email=self.normalize_email(email),
visiblename=visiblename,
agreement_status=agreement_status,
)
user.set_password(password)
user.save(using=self._db)
return user
def create_superuser(self, username, email, visiblename, agreement_status, password):
user = self.create_user(
username=username,
email=self.normalize_email(email),
visiblename=visiblename,
agreement_status=agreement_status,
password=password,
)
user.is_admin = True
user.permission = UserPermissions.OTHER
user.save(using=self._db)
return user
class UserAccount(AbstractBaseUser):
userid = models.AutoField(primary_key=True)
username = models.CharField(max_length=20, unique=True)
visiblename = models.CharField(max_length=40, unique=True)
email = models.EmailField(max_length=255, unique=True)
permission = models.IntegerField(default=UserPermissions.USER, choices=UserPermissions.choices)
agreement_status = models.JSONField()
date_joined = models.DateTimeField(auto_now_add=True)
date_lastlogin = models.DateTimeField(auto_now=True)
is_active = models.BooleanField(default=True)
is_blocked = models.BooleanField(default=False)
is_blocked_anon = models.BooleanField(default=False)
block_reason = models.TextField(default="", blank=True)
is_admin = models.BooleanField(default=False)
USERNAME_FIELD = 'username'
EMAIL_FIELD = 'email'
REQUIRED_FIELDS = ['email', 'visiblename']
objects = UserAccountManager()
def __str__(self):
return self.username
def has_perm(self, perm, obj=None):
return self.is_admin
def has_module_perms(self, app_label):
return True
So, what can I do about this problem? Should I reset all the MariaDB databases? Or are there some better solutions?
