Hi,
I'm trying to make model that has itself as a foreign key, in an
attempt to store a reverse tree in Django.
However, I can't find a way to set a default value to
models.ForeignKey or make it optional.
My model is like this:
class Node(models.Model):
name = models.CharField(max_length=100)
parent = models.ForeignKey('self')
runserver doesn't complain, but whenever I try to enter data to the
model with Django's admin interface I get a "This field is required."
message, and it want's me to select a entry, but there are none.
