Comment (by BrandonWoodward):
I believe the following to be the easiest method.
1. Follow the preparations in
[https://code.djangoproject.com/ticket/25313#comment:18 Carsten's
solution].
2. Create a new app with no existing migrations and migrate an empty
migration.
{{{#!python
./manage.py startapp user
./manage.py makemigrations user --empty
./manage.py migrate user
}}}
3. Update the migration to match the timestamp of the initial auth
migration.
{{{#!python
./manage.py shell
>>> from django.db.migrations.recorder import MigrationRecorder
>>> auth_initial = MigrationRecorder.Migration.objects.get(app='auth',
name='0001_initial')
>>> user_initial = MigrationRecorder.Migration.objects.get(app='user',
name='0001_initial')
>>> user_initial.applied = auth_initial.applied
>>> user_initial.save()
}}}
4. Delete `user 0001_initial.py`, set `AUTH_USER_MODEL = 'user.user'` in
your settings then run `./manage.py makemigrations` after creating the
following `user` model.
{{{#!python
from django.contrib.auth import models as auth_models
class User(auth_models.AbstractUser):
class Meta:
db_table = 'auth_user'
}}}
5. Update the content types
{{{#!python
./manage.py shell
>>> from django.contrib.contenttypes.models import ContentType
>>> ContentType.objects.filter(app_label='auth',
model='user').update(app_label='user')
}}}
6. Delete the model inherited from `auth_models.AbstractUser` and create
your custom user model. Run `makemigrations` then `migrate` after making
your changes and from this point on everything should be working properly.
{{{#!python
class User(auth_models.AbstractBaseUser,
auth_models.PermissionsMixin):
...
}}}
