create a django user while creating a records for model

Question

models.py as below,

from django.db import models
from django.contrib.auth.models import User

class members(models.Model):

    auto_id = models.AutoField(primary_key=True)
    member_name = models.OneToOneField(User)
    owner = models.ForeignKey('auth.User', related_name='webapi', on_delete=models.CASCADE)
    father_name = models.CharField(max_length=25, blank=False, default='')
    wife_name = models.CharField(max_length=25, blank=False, default='')
    number_of_child = models.IntegerField(blank=True)
    address_line_1 = models.CharField(max_length=40, blank=False, default='')
    address_line_2 = models.CharField(max_length=40, blank=True, default='')
    city = models.CharField(max_length=25, blank=False, default='')

    class Meta:
        ordering = ('member_name',)

Now The above has been linked with django auth Users table and in steriliser it shows the existing Django users and I have to choose one during the submit.

But my requirement is as a admin user I login and then provide the member_name manually which should automatically create a django user also

Answer 1

django-annoying has a feature for this, specifically AutoOneToOneField .

Sample from their github:

from annoying.fields import AutoOneToOneField

class MyProfile(models.Model):
    user = AutoOneToOneField(User, primary_key=True)

This should automatically create a User.
