Example:
class Author(models.Model): first_name = models.CharField() last_name = models.CharField() def _get_full_name(self): return '{0} {1}'.format(self.first_name, self.last_name) full_name = property(_get_full_name) What's the recommended way of putting a unique constaint on the full_name? Was thinking of overwriting save but maybe there are better solutions?
Take a look at the Meta class option unique_together
You could do it this way:
class Author(models.Model): first_name = models.CharField() last_name = models.CharField() def _get_full_name(self): return '{0} {1}'.format(self.first_name, self.last_name) full_name = property(_get_full_name) class Meta: unique_together = ("first_name", "last_name") The advantage is that this is enforced at the DB level with the proper UNIQUE SQL statements.
unique_together = ("first_name", "last_name")
