Hi,
I am testing a project with the 1.7Beta release / master branch and Django
can't load some fixtures when I am running my test-suite:
{{{

My models are :
{{{
from django.contrib.sites.models import Site
from django.contrib.auth.models import User
class SupportManager(models.Manager):
def get_current(self):
return self.get(pk=settings.SITE_ID)
def get_by_natural_key(self, short_name):
return self.get(short_name=short_name)
class Support(Site):
short_name = models.CharField('nom court', max_length=10, unique=True)
logo = models.ImageField('logo', upload_to='images/supports',
blank=True)
site_ptr = models.OneToOneField(Site, primary_key=True) # allow to do
select related without an extra query to Site.
objects = SupportManager()
def __unicode__(self):
return self.name
def natural_key(self):
return (self.short_name,)
class Organisation(models.Model):
name = models.CharField(max_length=100)
short_name = models.CharField('nom court', max_length=16)
class Employe(User):
supports = models.ManyToManyField(Support)
organisation = models.ForeignKey('Organisation', null=True,
blank=True)
filtre_organisation = models.BooleanField(default=False)
telephone = models.CharField(u'téléphone', max_length=100, blank=True)
class Meta:
abstract = True
def __unicode__(self):
return self.get_full_name()
class Assistant(Employe):
class Meta:
verbose_name = 'chargé de clientèle'
}}}
The fixture causing the crash is a concat from the following dumps (master
version of dumpdata):
{{{
python manage.py dumpdata sites.Site --indent=2 --natural-foreign --pk=1
python manage.py dumpdata parametrage.Support --indent=2 --natural-foreign
--pk=1
python manage.py dumpdata auth.Group --indent=2 --natural-foreign --pk=2
python manage.py dumpdata auth.User --indent=2 --natural-foreign --pk=8
python manage.py dumpdata parametrage.Assistant --indent=2 --natural-
foreign --pk=8
}}}
Which is :
{{{

Any idea ?
Thanks.
