I just ran into this issue as well when updating an old project to Django 1.8. The only suitable workaround I found was to update first to Django 1.7 and fake the initial migrations for my apps (presumably Django's as well, though it seems to handle that automatically). Only then can you safely update to Django 1.8. Otherwise, there is no way to fake only the initial migrations for the auth and contenttypes apps if you've already upgraded to Django 1.8 (perhaps there should be?).

While poking around with this again, I noticed that the thing causing the error for me was a datamigration (being applied due to it being run in tests) which is (I believe) why I was seeing the issue when trying to run tests but not otherwise. I was trying to grab a contenttype using ContentType.objects.get_for_model(MODEL). So my current belief is that no ContentType was created for that MODEL before that datamigration was run, thus causing it to fail the creation causing the error. Hope that helps.

By deleting the rows with contenttypes on it, deleting the contenttypes table and running the migration again I was able to fix the issue.

That was the problem I had faced- it wasn't a Django problem, it was a problem with my migration.On Mon, Jun 22, 2015 at 3:52 PM Chris DiLorenzo <dilorenzo....@gmail.com> wrote:I'm seeing this issue as well. Not sure if it helps but I get it when running my tests.I chose to raise the error instead and saw this:
DETAIL: Failing row contains (1, null, app, listing).Where app is the django app name and listing is the model name. So that sounds to me like I'm seeing what everyone else is, the migration is just not applied on the database for some reason, but shows as being applied OK.// Chris

The problem was that since 1.8 contenttypes started to have migrations. But since the table already existed earlier, the migrations needed to be faked.When faking the migrations, I used python manage.py migrate contenttypes --fake which faked both 0001 and 0002.The fix was to remove the fake migration for 0002 from django_migrations table and then do the actual migration.On Wed, Jun 10, 2015 at 6:57 AM Tim Graham <timog...@gmail.com> wrote:If anyone running into this problem can figure out why the contrib.contenttypes migration (0002_remove_content_type_name) is being marked as applied but not actually run in the database, that will help determine if this is a bug in Django or a problem elsewhere.--

The code in question is doing a get_or_create() on the contenttype object. I assume it should be picking up the name from the name @property on the ContentType model, but I don't see that ever actually being called.
