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...

Comment (by cx44yale):
I suspect it is a problem with the order executed, the M2M expects my User
model.
I removed all of my models definition in that app, and run python
manage.py migrate to generate all those auth, sessions builtin tables, and
then paste my models back run migrate again, this time everything works,
and all the tables are generated correctly.
Thanks

Comment (by timgraham):
Did you create migrations for your app using `makemigrations`? If not, you
have an unmigrated app depending on a migrated one as described
[https://docs.djangoproject.com/en/1.8/topics/migrations/#dependencies in
the docs] which is an invalid configuration.
