ProgrammingError: relation "django_content_type" does not exist

[andreav]

Hi,
I just migrated to django 1.8

My operations are:

1. scratch whole db
2. remove all migartions from my apps
3. manage.py makemigrations
4. manage.py migrate

However I get this error after "manage.py migrate" command:

django.db.utils.ProgrammingError: relation "django_content_type" does not exist

The sql command causing the error is:

u'ALTER TABLE "djangoratings_vote" ADD CONSTRAINT "djan_content_type_id_34170de97babd8e2_fk_django_content_type_id" FOREIGN KEY ("content_type_id") REFERENCES "django_content_type" ("id") DEFERRABLE INITIALLY DEFERRED'

If a comment out djangoratings from INSTALLED_APPS, the migrations finishes without problems.

If I issue a "./manage.py showmigrations" I get empty migrations for django ratings.

contenttypes
 [ ] 0001_initial
 [ ] 0002_remove_content_type_name
djangoratings
 (no migrations)                     <------------ strange this
guardian
 [ ] 0001_initial

The exception is raised when running deferred SQL.

Creating tables...
    Creating table thumbnail_kvstore
    Creating table djangoratings_vote
    Creating table djangoratings_score
    Creating table djangoratings_similaruser
    Creating table djangoratings_ignoredobject
    Running deferred SQL...
Traceback (most recent call last):
  File "./manage.py", line 10, in <module>

I will continue investigating but maybe you know/have a solution.

Thank you.

I just tried the same commands with django 1.9 and the migration successfully terminates!

However at the moment I cannot update to Django1.9 due to lack of support from other applications, so I'm still looking for a solution.

At the moment I can get the complete migration splitting the migration by steps:

./manage.py migrate contenttypes
./manage.py migrate auth
./manage.py migrate sites
./manage.py migrate my_custom_auth_app
./manage.py migrate

and this will complete my migrations.

I got errors during migration but everything seems to work in the end.

By the way, I could not run just:
manage.py migrate contenttypes && manage.py migrate
because contenttypes depends on auth_permission, but auth_permission depends on sites, and sites depends on my_custom_auth_app (maybe related to https://code.djangoproject.com/ticket/24075 but I'm not sure)
