Django AttributeError: 'UserManager' object has no attribute 'create_superuser' - django

Question

My question seems similar to this one, but the answer and explanation did not seem adequate, so I'm going ahead with a custom auth_user_model issue that is beyond my understanding. My app/users/model.py is like so:
from django.contrib.auth.models import (
BaseUserManager,AbstractBaseUser)
from django.contrib.auth.models import PermissionsMixin
from django.db import models
class MyUserManager(BaseUserManager):
def create_user(self, email, password,name=''):
"""
Creates and saves a User with the given email, password
"""
if not email:
raise ValueError('Users must have an email address')
user = self.model(
email=self.normalize_email(email),
name=name
)
user.set_password(password)
user.save(using=self._db)
return user
def create_superuser(self,email,password,name=''):
user = self.create_user(email,name=name,password=password)
user.is_admin = True
user.is_active = True
user.is_superuser = True
user.save(using=self._db)
return user
class MyUser(AbstractBaseUser,PermissionsMixin):
email = models.EmailField(
verbose_name='email',
max_length=255,
unique=True,
)
name = models.CharField(max_length=255,blank=True,default='')
is_active = models.BooleanField(default=False)
is_admin = models.BooleanField(default=False)
objects = MyUserManager()
USERNAME_FIELD = 'email'
#REQUIRED_FIELDS = ['name']
def get_full_name(self):
return self.name if self.name else self.email
def get_short_name(self):
return self.email
def __unicode__(self):
return self.email
#property
def is_staff(self):
return self.is_superuser
My stack trace is as follows:

AttributeError: 'MyUserManager' object has no attribute 'create_superuser'
I cant for the life of me figure out why this error is occuring. I'm using Django 1.9.1, with Python 2.7.11, with pydanny's cookiecutter django module. Relevant installed apps include djstripe, and allauth. Djstripe mostly works under these conditions, but I am unable to create a superuser, or login to the admin area.
At a loss here, so I hope a Django jedi can steer me in better direction, with some type of explanation. Thanks
