Can not create South database models in Django 1.7

Question

Django 1.7 has built-in database migration mechanizm. However, I'd like to run South migrations for the ols third-party django apps.

I failed to to 'syncdb' management command with Django 1.7 in order to create South models:

/south/management/commands/syncdb.py", line 82, in handle_noargs
old_app_store, cache.app_store = cache.app_store, SortedDict([

AttributeError: 'Apps' object has no attribute 'app_store'

Now getting this error on syncdb: /south/hacks/django_1_0.py", line 68, in clear_app_cache self.old_app_models, cache.app_models = cache.app_models, {} AttributeError: 'Apps' object has no attribute 'app_models' — Daria, May 19 '14 at 04:38

If you started a project on Django 1.6 but have upgraded to Django 1.7, you may not see this error immediately. But if you then do a fresh checkout and db build for the project, this mysterious error will crop up.

The solution is to remove South from your INSTALLED_APPS (and likely pip's requirements.txt as well). You don't need them anymore.

Thank you, I have decided not migrate to Django 1.7 until it is not stable. – Daria Jun 04 '14 at 08:07

On official South site:

South will not work with Django 1.7; it supports only versions 1.4, 1.5 and 1.6.

The only solution I can see is to create django 1.7 for third-party applications within your project using MIGRATION_MODULES setting. When these third-party applications will supply django 1.7 migrations. you should remove your migrations and do migrate --fake with application migrations.

I have not tried this solution because the project I needed it for is finished on Django 1.6, but looks like your answer is the closest. – Daria Sep 15 '14 at 03:06

https://docs.djangoproject.com/en/1.7/topics/migrations/#upgrading-from-south

This is part of the stable 1.7 release. You should utilise this process if you're upgrading from 1.6 to 1.7

Thank you, now that 1.7 release is stable, it is possible. But I was asking about 3d party Django apps I am using in my project. I can't just remove their migrations. Hopefully, the rest of Django community will move on soon. – Daria Sep 08 '14 at 04:13
