How to solve error raised : No module named 'django.contrib.customuser' - django

Question

I am new to Django, trying to create a custom user for my project. When I am running the server, it raises No module named 'django.contrib.customuser' and sometimes, Manager isn't available; auth.User has been swapped for Mysite.CustomUser. Even i changed my settings: django.contrib.auth to django.contrib.custommuser. Please someone help me solving this. Here's my code
models.py:

now = datetime.now()
if not email:
raise ValueError('Users must have an email address')
email = self.normalize_email(email)
user = self.model(username=username, email=email, u=u, password=password,
is_staff=is_staff, is_active=False, last_login=now, date_joined=now, **extra_fields)
user.set_password(password)

Answer 1

Remove django.contrib.customuser and django.contrib.auth from your INSTALLED_APPS. There is no customuser application under django.contrib package, and auth can be omitted (to avoid potential name colission).
Furthermore, I suggest you re-read the Django docs on auth customization. Most of the changes are optional, and your code should be simplified by re-using the base classes, unless your methods vary of course.
The docs also mentions that for swapping User models, you are required to update settings to AUTH_USER_MODEL = 'customuser.CustomUser'.
