Django - AttributeError

Question

I created my custom User model. While doing migrations, I get an AtrributeError

from django.db import models
from time import timezone
from django.contrib.auth.models import AbstractBaseUser, BaseUserManager
from django.core.mail import send_mail
from django.utils.http import urlquote
from django.utils.translation import ugettext_lazy as _


class CustomUsermanager(BaseUserManager):
    def _create_user(self, is_anonymous, first_name, last_name, email, username, password, home_address, user_type, image_path):
        now = timezone.now()

        if not email:
            raise ValueError('The gives emial must be set')

        email = self.normalize_email(email)
        user = self.model(
            is_anonymous=is_anonymous,
            first_name=first_name,
            last_name=last_name,
            email=email,
            username=username,
            home_address=home_address,

            image_path=image_path,
            created_time=now,
            last_login=now
        )

        user.set_password(password)
        user.save(using=self._db)
        return user

    def create_a_admin(self, first_name, last_name, email, username, password, home_address, image_path):
        return self._create_user(1, first_name, last_name, email, username, password, home_address, 0, image_path)

    def create_a_nonanonymous_patient(self, first_name, last_name, email, username, password, home_address, image_path):

    def create_an_anonymous_helper(self, first_name, last_name, email, username, password, home_address, image_path):
        return self._create_user(1, first_name, last_name, email, username, 2, password, home_address, 2, image_path)

    def create_a_prof(self, first_name, last_name, email, username, password, home_address, image_path):
        return self._create_user(0, first_name, last_name, email, username, 3, password, home_address, 3, image_path)


class CustomUser(AbstractBaseUser):
    is_anonymous = models.BooleanField()
    username = models.CharField(max_length=255, unique=True)
    first_name = models.CharField(max_length=255, blank=True)
    last_name = models.CharField(max_length=255, blank=True)

    user_type = models.IntegerField(1)
    image_path = models.CharField(max_length=500, blank=True)
    created_time = models.TimeField()

    USERNAME_FIELD = 'username'
    REQUIRED_FIELDS = ['username', 'home_address', 'first_name', 'last_name', 'user_type']

    objects = CustomUsermanager()

    class Meta:
        verbose_name = _('user')
        verbose_name_plural = _('users')

    def get_absolute_url(self):
        return '/users/%s/' % urlquote(self.email)

    def get_full_name(self):
        full_name = '%s %s' % (self.first_name, self.last_name)
        return full_name.strip()

    def get_short_name(self):
        return self.first_name

    def get_email_user(self, subject, message, from_email=None):
        send_mail(subject, message, from_email, [self.email])

and the exception is:

AttributeError: can't set attribute

Can anybody point out where is wrong?

Answer 1

user = self.models(
        is_anonymous=is_anonymous,
        first_name=first_name,
        last_name=last_name,
        email=email,
        username=username,
        home_address=home_address,
        user_type=user_type,
        image_path=image_path,
        created_time=now,
        last_login=now
    )

replace models
