django - LookupError: App 'users' doesn't have a 'user' model -

django 1.9.7 i'm using pyenv virtualenv autoenv

i want extend user model so, decide use abstractuser

(abstractuser's class meta abstract = true, can't make table, inheritance class can make table, right??)

anyways

(wef project name) make app wef/users/models/__init__.py

from .user import user 

in wef/users/models/user.py

from django.contrib.auth.models import abstractuser  django.db import models   class user(abstractuser):      phonenumber = models.charfield(             max_length = 11,             blank = true,             null = true             ) 

and add usersapp in settings.py

installed_apps = [     [...]     'users', ]  auth_user_model = 'users.user' 

so, think when makemigrations, migrate

django make model table user...

python wef/manage.py makemigrations users

it shows error

i can't understand why django can't found users.user model

and when change `auth_user_model=useraaa'

it show error (capital letters changed lower case)

lookuperror: app 'users' doesn't have 'useraaa' model.

i can not find problem please me.. ㅠ_ㅠ

i think have created database schema. django documentation:

changing auth_user_model has big effect on database structure. changes tables available, , affect construction of foreign keys , many-to-many relationships. if intend set auth_user_model, should set before creating migrations or running manage.py migrate first time.

changing setting after have tables created not supported makemigrations , result in having manually fix schema, port data old user table, , possibly manually reapply migrations.
