Custom User Model: No such table exits while creatingsuperuser

Question

I am trying to build a custom user model which I had did successfully in a previous project. But for some reason this is time I am met with this weird error, which I have gone through stackoverflow and find a fix for this. I try to do makemigrations and it shows no migrations to make and I simply do migrate and assume new table is created but then I try to create a superuser and this shows up. So did I miss a step or something? Things that might be informative, I had a previous in built model migrated and trying to create new one by deleting the database file of old one, I have deleted the previous migrations of all other Apps, I have added app and auth_user_model in the settings.

Settings.py

# Custom Model
AUTH_USER_MODEL = "user.CustomUser"

# Application definition
INSTALLED_APPS = [
    'django.contrib.admin',
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.messages',
    'django.contrib.staticfiles',

    # Custom
    "home",
    "user",
]

users/models.py

from django.db import models
from django.utils.translation import gettext_lazy as _
from django.contrib.auth.models import AbstractBaseUser, PermissionsMixin, BaseUserManager


class CustomUserManager(BaseUserManager):

    def create_superuser(self, email, password, **other_fields):

        other_fields.setdefault('is_staff', True)
        other_fields.setdefault('is_superuser', True)
        other_fields.setdefault('is_active', True)

        if other_fields.get('is_staff') is not True:
            raise ValueError(
                'Superuser must be assigned to is_staff=True.')
        if other_fields.get('is_superuser') is not True:
            raise ValueError(
                'Superuser must be assigned to is_superuser=True.')

        return self.create_user(email, password, **other_fields)

    def create_user(self, email, password, **other_fields):

        if not email:
            raise ValueError(_('You must provide an email address'))

        email = self.normalize_email(email)
        user = self.model(email=email, **other_fields)
        user.set_password(password)
        user.save()
        return user


class CustomUser(AbstractBaseUser, PermissionsMixin):

    email = models.EmailField(_('email address'), unique=True)
    # user_name = models.CharField(max_length=150, unique=True)
    # first_name = models.CharField(max_length=150, blank=True)
    # start_date = models.DateTimeField(default=timezone.now)
    # about = models.TextField(_(
    #     'about'), max_length=500, blank=True)
    is_staff = models.BooleanField(default=False)
    is_active = models.BooleanField(default=False)

    objects = CustomUserManager()

    USERNAME_FIELD = 'email'
    # REQUIRED_FIELDS = ['user_name', 'first_name']

    def __str__(self):
        return self.email
