Hello,
I got some errors by using the Meta options order_with_respect_to:
<code>
class Category(PublicationBase, LocalisationBase):
ITEM_PER_PAGE = 12
name = models.CharField(max_length=255)
pictogram = models.ImageField(upload_to="categories", blank=True)
old_id = models.PositiveIntegerField(blank=True)
parent = models.ForeignKey("Category", blank=True, null=True)
class Meta:
ordering = ['name']
order_with_respect_to = 'parent'
def __unicode__(self):
return self.name
</code>
An I got this error :
<code>

I found this ticket (http://code.djangoproject.com/ticket/2740), but I
don"t want to patch django. Any Idea for a workaround ?
