auth User in data migration: AttributeError: type object 'User' has no attribute 'normalize_username'

[Павел Фролов]

Hello everybody,

could somebody help me

I try to do data migration. Migration uses User from auth. Django 1.10.4

def create_superuser(apps, schema_editor):

    User = apps.get_model("auth", "User")

    User.objects.create_superuser(username='admin', password='admin123admin', email='')

class Migration(migrations.Migration):

    dependencies = [

        ('auth', '__latest__'),

    ]

    operations = [

        migrations.RunPython(create_superuser),

    ]

I got an error:

...

File "/Projects/django/src/testdb/migrations/0001_initial.py", line 10, in create_superuser

    User.objects.create_superuser(username='admin', password='admin123admin', email='')

  File "/Projects/django/venv/lib/python3.4/site-packages/django/contrib/auth/models.py", line 168, in create_superuser

    return self._create_user(username, email, password, **extra_fields)

  File "/Projects/django/venv/lib/python3.4/site-packages/django/contrib/auth/models.py", line 148, in _create_user

    username = self.model.normalize_username(username)

AttributeError: type object 'User' has no attribute 'normalize_username'

I use standard User in my project and I need perform data migrations.

thank you in advance

Pavel

I found information here https://groups.google.com/forum/#!searchin/django-users/auth$20user$20in$20migration|sort:relevance/django-users/Zz9rKT7GVM0/u6A4HzgDylkJ
but I want not use "patching"

I did following:

def create_superuser(apps, schema_editor):

    # fixme: User = apps.get_model("auth", "User")

    from django.contrib.auth.models import User

    User.objects.create_superuser(username='admin', password='admin123admin', email='')

It works

I think this is another symptom of https://code.djangoproject.com/ticket/26445.
