Hi,
I have the following abstract model, but it's child models fail saving
with RuntimeError: maximum recursion depth exceeded
class AcceptedRoleAbstract(models.Model):
'''
Represents a User that should accept a role
E.g.: Discutant, Reviewer
'''
user = models.OneToOneField(User)
accepted = models.NullBooleanField(help_text=_("The reviewer
agreed to make the review"))
updated = models.DateTimeField(auto_now=True)
created = models.DateTimeField(auto_now_add=True)
class Meta:
abstract = True
def __unicode__(self):
return u'%s accepted: %s' % (self.user.get_full_name() or
self.user.username, str(self.accepted))
def save(self, force_insert=False, force_update=False):
if self.pk:
old_accepted = self.__class__.objects.get(pk=self.pk)
else:
old_accepted = False
super(self.__class__, self).save(force_insert, force_update)
if not old_accepted == self.accepted and self.accepted==False:
message = render_to_string('conference/
new_role_rejects_message.txt', {'object': self})
mail_managers(_('A %s canceled his demand' %
self.__class__), message)
the child models are really simple:
class Discutant(AcceptedRoleAbstract):
'''
Represents a discutant
'''
class Meta:
verbose_name = _('discutant')
verbose_name_plural = _('discutants')
thanks for your help!
