Re: Unable to create migration with Error - One or more models did not validate:

Hi,

you've added a relation to the AssetPollingConfig model which is not defined.

Cheers

Hello,

I have following model definition and when I try to create a migration
using command,  'python manage.py schemamigration asset_mgmt
--initial' I am getting following error:

CommandError: One or more models did not validate:
asset_mgmt.alarmtable: 'polling_config' has a relation with model
AssetPollingConfig, which has either not been installed or is
abstract.

I have other classes that extend the TimeStampedModel and I don't see
this error, can someone point me towards reason I am getting this
error?


class TimeStampedModel(models.Model):
    created = models.DateTimeField(auto_now_add=True)
    modified = models.DateTimeField(auto_now=True)
    class Meta:
        abstract = True

class AssetPollingInfo(TimeStampedModel):
    id = models.AutoField(primary_key=True)
    alarm_text = models.CharField(max_length=800,blank=True,null=True)
    asset_id = models.ForeignKey('AssetInfo')
    thresholds = models.ForeignKey('ThresholdInfo')
    dispatch = models.ForeignKey('AlarmDispatchInfo')
    class Meta:
        ordering = ['-id']
    def __unicode__(self):
        return str(self.id)

class AlarmTable(TimeStampedModel):
    id = models.AutoField(primary_key=True)
    polling_config = models.ForeignKey('AssetPollingConfig')
    alarm_text = models.CharField(max_length=800,blank=False,null=False)
    event_type = models.SmallIntegerField(blank=False,null=False)
    trigger_point = models.IntegerField(blank=True,null=True)
    class Meta:
        ordering = ['-id']
    def __unicode__(self):
        return str(self.id)
