I tried to set up custom user model by inheriting from AbstractBaseUser as instructed in django documentation, but I am encountering relation "auth_user" does not exist error.

#models.py
from django.db import models
from django.contrib.auth.models import (BaseUserManager, AbstractBaseUser)

class MyUserManager(BaseUserManager):
def create_user(self, email, date_of_birth, password=None):
"""Creates and saves the user with the given email, DOB and password"""
if not email:
raise ValueError('Users must have an email address')
user = self.model(email=self.normalize_email(email),date_of_birth=date_of_birth,)
user.set_password(password)
user.save(using=self._db)
return user

def create_superuser(self, email, date_of_birth, password):
"""Creates and saves a superuser with the given email, date of birth and password."""
user = self.create_user(email, password=password, date_of_birth=date_of_birth)
user.is_admin = True
user.save(using=self._db)
return user

class MyUser(AbstractBaseUser):
email = models.EmailField(verbose_name='email address', max_length=255, unique=True,)
date_of_birth = models.DateField()
is_active = models.BooleanField(default=True)
is_admin = models.BooleanField(default=False)

objects = MyUserManager()

USERNAME_FIELD = 'email'
REQUIRED_FIELDS = ['date_of_birth']

def get_full_name(self):
return self.email
def get_short_name(self):
return self.email
def __str__(self):
return self.email
def has_perm(self, perm, obj=None):
return True
def has_module_perms(self, app_label):
return True
@property

return self.is_admin

from django.contrib import admin

from django.contrib.auth.admin import UserAdmin as BaseUserAdmin

user.set_password(self.cleaned_data["password1"])

user.save()
return user

def clean_password(self):
return self.initial["password"]
        # Regardless of what the user provides, return the initial value.
        # This is done here, rather than on the field, because the
        # field does not have access to the initial value

# Now register the new UserAdmin...
admin.site.register(MyUser, UserAdmin)

# unregister the Group model from admin.
admin.site.unregister(Group)

</form>

I have also configured settings.py as instructed in the documentation.
Please help.

Hi,

Have you tried running ./manage.py makemigrations and then ./manage.py migrate? That's needed to actually create the table.
