Hi,
first, my models:
class Connection(models.Model):
p1 = models.ForeignKey(SinglePoint, related_name='p1_set',
help_text="Punkt 1")
p2 = models.ForeignKey(SinglePoint, related_name='p2_set',
help_text="Punkt 2")
...
class Meta:
unique_together = (('p1', 'p2'),('p2','p1'))
class SinglePoint(models.Model):
name = models.CharField(max_length=100)
...
With that code I can create 2 Connections like:
Connection 1: p1 = A, p2 = B
Connection 2: p1 = B, p2 = A
But I want to disallow that way, I wish to have just
Connection 1: p1 = A, p2 = B
OR
Connection 2: p1 = B, p2 = A
and not both. How is this possible?
Thank you very much!!
Christian
