I do not think that admin currently supports this, but I could be wrong. but
here are two ways to accomplish it.
class Item(models.Model):
name = models.CharField(max_length=30)
class ItemOrder(models.Model):
item = models.FK(Item)
order = models.int()
def __unicode__(self): return ('%s - %s'
%(self.item.__unicode__(), self.order))
class Page(models.Model):
survey = models.ForeignKey(Survey)
item = models.M2M(ItemOrder)
order = models.IntegerField() #Page Order
file_name = models.CharField(max_length=50)
You can also add a 'unique_together' constraint to your meta class in
ItemOrder, if helpful.
