Re: Using data migration to create initial users errors

Hey Ben.

The only gotcha I had is that the password needs to be hashed. 
I ended up doing this to create a superuser:

from django.db import migrations

from django.contrib.auth.hashers import make_password

def create_admin_user(apps, schema_editor):

    User = apps.get_registered_model('auth', 'User')

    admin = User(

        username='admin',

        email='admin@admin.com',

        password=make_password('cambiame'),

        is_superuser=True,

        is_staff=True

    )

    admin.save()

 

class Migration(migrations.Migration):

    dependencies = [

        ('auth', '0001_initial')

    ]

    operations = [

        migrations.RunPython(create_admin_user),

    ]

I know it's a little bit late. But hope it helps.

I am trying to create initial users in Django 1.7 via a simple data migration like so:

# -*- coding: utf-8 -*-
from __future__ import unicode_literals

from django.conf import settings
from django.contrib.auth import get_user_model
from django.db import models, migrations


def populate_initial_data(apps, schema_editor):

    
    User = apps.get_model(settings.AUTH_USER_MODEL)
    Group = apps.get_model('auth', 'Group')

    user = User.objects.create_user("test", email="te...@test.com", password="test")
    # AttributeError: 'Manager' object has no attribute 'create_user'

    group = Group.objects.create(name="Test Group")
    user.groups.add(group)


class Migration(migrations.Migration):

    dependencies = [
        ('auth', '__first__')
    ]

    operations = [
        migrations.RunPython(populate_initial_data)
    ]

However the instance of User does not have a UserManager, but rather a vanilla Manager object?

Possibly related problem, if I instead retrieve User via get_user_model() then I get a type error attempting to add that user to a group, like so:

# -*- coding: utf-8 -*-
from __future__ import unicode_literals

from django.conf import settings
from django.contrib.auth import get_user_model
from django.db import models, migrations


def populate_initial_data(apps, schema_editor):


    User = get_user_model()
    Group = apps.get_model('auth', 'Group')

    user = User.objects.create_user("test", email="te...@test.com", password="test")
    group = Group.objects.create(name="Test Group")
    user.groups.add(group)
    # TypeError: 'Group' instance expected, got <Group: Group object>


class Migration(migrations.Migration):

    dependencies = [
        ('auth', '__first__')
    ]

    operations = [
        migrations.RunPython(populate_initial_data)
    ]

I'm trying to replace the functionality of fixtures, which has apparently been deprecated with apps that use migrations.

Thanks!
