Hi, please help me create this UserManager child class. I 'm stuck up on this. I also need to divide my users into three groups. 

For this I extended the migrations file.   https://dpaste.org/9VSd. But running `makemigrations` gives no changes detected.

 Please help with this issue too.

Thanks in advance.

Another thing is that my "employees" group has an additional CharField requirement. Only the employees group.How can I add specifically a field to that group? Something this this:https://stackoverflow.com/questions/16407217/add-extra-fields-to-django-to-django-auth-groups

I did paste my `models.py` with the help the help of a dpaste link.

```

class UserManager( BaseUserManager):

    

    def _create_user(self, PAN_ID, password=None, **extra_fields):

        """

        Creates and saves a User with the given email, date of

        birth and password.

        """

        if not PAN_ID:

            raise ValueError('Users must have an email address')

        extra_fields['email'] = self.normalize_email(extra_fields["email"])

        user = self.model(PAN_ID=PAN_ID, **extra_fields)

        user.set_password(password)

        user.save(using=self._db)

        return user

    

    def create_user(self, PAN_ID, password=None, **extra_fields):

        extra_fields.setdefault('is_staff', False)

        extra_fields.setdefault('is_superuser', False)

        return self._create_user(PAN_ID, password, **extra_fields)

    

    def create_superuser(self, PAN_ID, password=None, **extra_fields):

        extra_fields.setdefault('is_staff', True)

        extra_fields.setdefault('is_superuser', True)

        if extra_fields.get('is_staff') is not True:

            raise ValueError('Superuser must have is_staff=True.')

        if extra_fields.get('is_superuser') is not True:

            raise ValueError('Superuser must have is_superuser=True.')

        return self._create_user(PAN_ID, password, **extra_fields)

```   The following code worked. I used https://simpleisbetterthancomplex.com/tutorial/2016/07/22/how-to-extend-django-user-model.html and the source code from https://github.com/django/django/blob/master/django/contrib/auth/models.py.   Can I get help in the migrations and creating groups? Code is in the dpaste s.

Hello Vishesh, 

Below is from my models.py:

models.py

-------------

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


class AccountManager(BaseUserManager):
    def create_superuser(self, email, password, **extra_fields):

        extra_fields.setdefault('is_staff', True)
        extra_fields.setdefault('is_superuser', True)

        extra_fields.setdefault('is_active', True)

        if extra_fields.get('is_staff') is not True:

            raise ValueError(_('Superuser must have is_staff=True.'))

        if extra_fields.get('is_superuser') is not True:

            raise ValueError(_('Superuser must have is_superuser=True.'))
        return self.create_user(email, password, **extra_fields)

    def create_user(self, email, password, **extra_fields):
        if not email:
            raise ValueError(_('Enter the email before proceeding'))

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


class Shop(AbstractBaseUser, PermissionsMixin):
    email = models.EmailField(unique=True)
    shop_name = models.CharField(max_length=150)
    contact = models.CharField(max_length=10)
    State = models.CharField(max_length=100)
    district = models.CharField(max_length=100)
    location = models.CharField(max_length=100)
    is_staff = models.BooleanField(default=False)
    is_active = models.BooleanField(default=True)
    date_joined = models.DateTimeField(auto_now_add=True)
    last_login = models.DateTimeField(null=True)

    objects = AccountManager()

    USERNAME_FIELD = 'email'
    REQUIRED_FIELDS = ['shop_name', 'contact', 'is_staff']

    def __str__(self):
        return str(self.shop_name)

See if that helps you out.

Amitesh

Oops I guess, my bad messaging style made you miss the last few pieces of my messages. Thanks, but that problem is resolved as written in my previous message with the working code. Now I require help with the Migrations problem.

[Amitesh Sahay]

Did you happen to remove the private method "def _create_user" from your models.py?

Regards,

Amitesh
