Hello!
First of all I want to apologize for maybe very basic question, but I
newbie in django and web coming from c/c++ world.
I have two models:
class Box(models.Model):
description = models.CharField(max_length=250)
id = models.IntegerField(primary_key=True)
def __unicode__(self):
return self.description
class Item(models.Model):
title = models.CharField(max_length=500)
box = models.ForeignKey(Box)
label = models.IntegerField()
def __unicode__(self):
return self.title
What I want is to enforce in some way uniqueness of pair (label, box)
for every item. So there may be items with the same label but they
must belong to different boxes.
