Hi,
I have the following very simple code:
from django.contrib.auth.models import User
class Agent(models.Model):
name = models.CharField(max_length=100)
users = models.ManyToManyField(User, related_name='accessible_agents',
default=[])
and when I have an empty database, and do python manage.py migrate.
It gives me error, and I tested on 1.7.8, it works fine.
Operations to perform:
Synchronize unmigrated apps: staticfiles, download, messages
Apply all migrations: admin, auth, contenttypes, sessions
Synchronizing apps without migrations:
Creating tables...
Creating table download_agent
Running deferred SQL...
