Hi all,
I'm trying to get an abstract model working in Django and I hit a brick wall trying to set the related_name per the recommendation here: http://docs.djangoproject.com/en/dev/topics/db/models/#be-careful-with-related-name
This is what my abstract model looks like:
class CommonModel(models.Model):
created_on = models.DateTimeField(editable=False)
creared_by = models.ForeignKey(User, related_name="%(app_label)s_%(class)s_created", editable=False)
updated_on = models.DateTimeField(editable=False)
updated_by = models.ForeignKey(User, related_name="%(app_label)s_%(class)s_updated", editable=False)
def save(self):
if not self.id:
self.created_on = datetime.now()
self.created_by = user.id
self.updated_on = datetime.now()
self.updated_by = user.id
super(CommonModel, self).save()
class Meta:
abstract = True
My common model is in [project_root]/models.py. It is the parent object of this model, which is located in an app called Feedback [project_root]/feedback/models.py:
from django.db import models
from mediasharks.models import CommonModel
class Feedback(CommonModel):
message = models.CharField(max_length=255)
request_uri = models.CharField(max_length=255)
domain = models.CharField(max_length=255)
feedback_type = models.IntegerField()
Basically I'm trying to set up a common model so that I'll always be able to tell when and by whom database entries were created.
When I run "python manage.py validate" I get this error message: KeyError: 'app_label'
Am I missing something here?
