Comment (by Ivan):
{{{
class Worker(models.Model):
fio = models.CharField(u'ФИО', unique=True, max_length=250)
active = models.BooleanField(default=True, help_text="Активный")
def __str__(self):
return self.fio
class WorkerActive(Worker):
def __str__(self):
if not self.active:
return "%s (Не кативен)" % (self.fio,)
return self.fio
class Meta:
proxy = True
class License(models.Model):
target_workers = models.ManyToManyField(WorkerActive,
verbose_name="Покупалась для", blank=True)
def __str__(self):
return u"License for %s (%s)" % (self.soft.name, self.number or
'')
}}}
I have error (1054, "Unknown column
'inventory_license_target_workers.workeractive_id' in 'field list'")
WHY!?
I believe that this is a gross error of the concept of using Proxy models
