InvalidBasesError: Cannot resolve bases for [<ModelState: 'cms.PageUser'>]

July 4, 2016, 2:19 a.m.

If you get this error:

django.db.migrations.state.InvalidBasesError: Cannot resolve bases for [<ModelState: 'cms.PageUser'>]

Then the problem is in migration of django cms. This migration try to refer to migrations of User model:

class Migration(migrations.Migration):

    dependencies = [
        ('auth', '__first__'),
        migrations.swappable_dependency(settings.AUTH_USER_MODEL),  # refer to migrations of User model
        ('sites', '__first__'),

And doesn't find, because there aren't migrations yet for our model of custom user. So before the creations of migrations you need comment djangocms_text_ckeditor and cms applications in

    'my_custom_auth',  # our custom User model

    # 'djangocms_text_ckeditor',
    # 'cms',

Run makemigrations: > makemigrations

Migrations for 'my_custom_auth':
    - Create model User

And then remove comment for djangocms_text_ckeditor and cms applications. That's all.
