Hi there,
Same problem here with a fresh checkout of stable/1.7.x when running my
tests (which used to works a few weeks ago):
{{{

I am not using migrations.
Here my models.py:
{{{
from django.contrib.sites.models import Site
from django.contrib.auth.models import User
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)
objects = SupportManager()
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
ordering = ('last_name', 'first_name')
def __unicode__(self):
return self.get_full_name()
def supports_txt(self):
return ', '.join([str(s) for s in self.supports.all()])
supports_txt.short_description = 'supports'
class Commercial(Employe):
class Meta:
verbose_name_plural = 'commerciaux'
ordering = ('first_name', 'last_name')
class Assistant(Employe):
class Meta:
verbose_name = 'chargé de clientèle'
verbose_name_plural = 'chargés de clientièle'
class Production(Employe):
class Meta:
verbose_name = 'chargé de production'
verbose_name_plural = 'chargés de production'
class Traducteur(Employe):
pass
}}}
Cheers,
Stanislas.
