I have used django in the past, but not for some time. So the changes
surrounding the user models are new to me. I downloaded v1.7b2 and
proceeded to start a new development I am planning. However I came across
a problem when trying to run migrate after generating the migrations on an
app that has a model that contains a foreign key to the user model. So I
created a simple test app to isolate the problem, with a model defined as
below:
from django.db import models
from django.conf import settings
class TestModel(models.Model):
user = models.ForeignKey(settings.AUTH_USER_MODEL)
When I run "makemigrations test_app" the migrations seem to be created fine
as there are no errors produced. However when I run "migrate" I get the
folllowing errors:
C:\Users\osborn_r\django\test_project>python manage.py migrate
Operations to perform:
Synchronize unmigrated apps: admin, contenttypes, auth, sessions
Apply all migrations: test_app, auth
Synchronizing apps without migrations:
Creating tables...
Installing custom SQL...
Installing indexes...
Running migrations:

Can anyone spot what I have done wrong?
