Hi,
I am new to django, and got some problems on models validation. I have
the following two models:
class A(models.Model):
...
class B(models.Model):
key_field = models.ForeignKey(A)
...
bool_field = models.BooleanField(default=False)
I want to add a validation rule in model B on this way:
for a special key_field there cannot be more than one entry with
bool_field=True
How can I have this?
Thanks,
Hovo
