I need to create a static method for a model class like this. The line
Settore.objects.all()[0].id gives error (
psycopg2.InternalError: current transaction is aborted) when creating
the tables at first syncdb. What's the correct way to do that?
~~~~~~~~~~~~~~~~~~~~~~~~~
class Settore(models.Model):
nome = models.CharField(max_length=200, blank=False, null=False)
email = models.EmailField()
class Meta:
verbose_name_plural = 'settori'
ordering = ('nome',)
get_latest_by = "nome"
def __unicode__(self):
return self.nome
@staticmethod
def get_default():
try:
return Settore.objects.all()[0].id
except:
return None
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
