Django South Error: AttributeError: 'DateTimeField' object has no attribute 'model'`

Question

So I'm trying to migrate a table by adding two columns to it. A startDate and an endDate. Using south for Django, this should be a simple migrate. I have loads of other tables with dateTimes in them as well, but for some reason I'm getting and issue here and I don't see it.

The stack trace is stating:

AttributeError: 'DateTimeField' object has no attribute 'model'

Here is the model I am migrating:

# Keep track of who has applied for a Job
class JobApply(models.Model):
    job = models.ForeignKey(Jobs)
    user = models.ForeignKey(User)
    # Keep track of the Developer accepted to do the work
    accepted_dev = models.IntegerField(null=False, blank=False, default=0)
    # If 1 (True) the User has applied to this job
    isApplied = models.BooleanField(default=0)
    startDate = models.DateTimeField()
    endDate = models.DateTimeField()

All the fields except for startDate and endDate already exist in the DB. So to give those columns default values I use datetime.date.now() through the terminal to keep everything square. The issue is that South's schemamigration works just fine, but the actual migration barfs.

If anyone can see the error, my hair would appreciate it. :P

EDIT: Including Stacktrace:

Migration Code (adding relevant code as it's a bit long):

def forwards(self, orm):
    # Adding field 'JobApply.startDate'
    db.add_column(u'insource_jobapply', 'startDate',
                  self.gf('django.db.models.fields.DateTimeField')(default=datetime.datetime(2013, 12, 7, 0, 0)),
                  keep_default=False)

    # Adding field 'JobApply.endDate'
    db.add_column(u'insource_jobapply', 'endDate',
                  self.gf('django.db.models.fields.DateTimeField')(default=datetime.datetime(2013, 12, 7, 0, 0)),

Answer 1

I had to upgrade my version of south for django to version 0.8.4.

Had to run the following command:

sudo easy_install -U South

Or, if using pip:

pip install South --upgrade

After that, my migration worked as expected.
