Hey,
What is the code of your managers and what's the full stacktrace?
You can use dpaste.de as a pastebin :)
For the related field, iirc, it's recommended to reference them with a
string.
try to change this
cards = models.ManyToManyField(Card, blank=True)
by:
cards = models.ManyToManyField('app.Card')

Hi :
I am new in Django, and I meet a bug.
I was upgrade django from 1.5 to 1.8.
My Django environment now is : Django 1.8.5 with python 2.7.10
This is my auth models:
Class Card(models.Model):
cardgroup = models.CharField(_('CardGroup'), max_length=60)
cardname = models.CharField(_('CardName'), max_length=60)
disabled = models.BooleanField(_('disabled'), default=False)
objects = CardManager()
class Meta:
unique_together = (cardgroup', 'cardname')
def __unicode__(self):
return self.name
@property
def name(self):
return '%s_%s' % (.self.cardgroup, self.cardname)
Class Factory(models.Model):
sort = models.CharField(_('Short Name'), max_length=20, unique=True)
address = models.CharField(_('Factory address'), max_length=20)
cards = models.ManyToManyField(Card, blank=True)
def __unicode__(self):
return self.short
After "#python manage.py migrate" twice , I got a error:
ValueError: Lookup failed for model referenced by
fieldcore.auth.Factory.card:core.auth.core.auth.Card
Because of that, I cannot syncdb ,either.
My auth apps was included in a core floder.
Help me fix the bug, please. I wascoming unstuck for a mouth.
