When upgrading to Django 1.8 (with zc.buildout) and running syncdb or migrate, I get this message:
django.db.utils.ProgrammingError: relation \"auth_user\" does no
I've migrated an old Django 1.6 project to Django 1.8 and previously we've used syncdb to migrate the database and we did not have initial migration steps for all apps in our project. With Django 1.8, you'll need a working database migrations. Running
manage.py makemigrations <app_name>
for all apps in our project fixed our problems.
Try referring to the User using this
from django.conf import settings
user = models.ForeignKey(settings.AUTH_USER_MODEL, related_name='%(app_label)s_%(class)s_user', blank=True, null=True, editable=False)
On my environment, I fix this running makemigrations
on all apps that have relationship with django.contrib.auth.models
:
manage.py makemigrations app_with_user_relation manage.py migrate
To fix this problem here is what I did:
1) Find all foreign key relation fields like OneToOneField, ForeignKey and ManyToManyFields in your project, including any reusable apps that are referring to auth.User
or import User and set it to settings.AUTH_USER_MODEL as above. At minimum use:
'auth.User'
2) For all the models that have the above, make sure the models have a valid django migration (not south). If they have south migrations, rename the directory to migrations_south and then run the makemigrations command for that app:
./manage.py makemigrations affected_app
Sometimes there is a django migrations folder under a different name, not the default migrations
directory. In such cases, reference this via MIGRATION_MODULES
in your settings.py:
MIGRATION_MODULES = {'filer': 'filer.migrations_django'}
Since the issue was hard to find on larger projects, I commented out all custom apps in INSTALLED_APPS
in settings.py and ran the test command, since it will run migrate and try to re-create the database for you:
./manage.py test
Looks like that fixed it for me. I'm not sure if step 1 is mandatory or just best practice. But you definitely need to convert the apps to migrations.
Cheers!
PS. Be ready for what's coming in Django 1.9. The syncdb command will be removed. The legacy method of syncing apps without migrations is removed, and migrations are compulsory for all apps.
If you are using heroku like I was run
heroku run python manage.py makemigrations
This will likely give you a message saying there are now changes. Ignore that then run
heroku run python manage.py migrate
this will give you some output suggesting something has been done. Finally run
heroku run python manage.py createsuperuser
I fix this by running auth first, then the rest of my migrations:
python manage.py migrate auth
python manage.py migrate
