I have a model that can be attached to a variety of different models,
based on the value of a column. Is there any way to map this
relationship in Django? If not, is there a way to automatically do
post-fetch processing where I could populate it?
Here is a example:
class Note(models.Model):
owner_id = models.IntegerField() #this is the FK of the related
object
owner_type = models.CharField(max_length=40) # this can either be
"Account" or "Ticket"
note = models.TextField()
class Account(models.Model)
name = models.CharField(max_length=40)
...
class Ticket(models.Model)
subject = models.CharField(max_length=120)
...
So basically, we can attach Notes to either Account or Ticket. The
"owner_id" field will be the primary key of the object being attached
to. The "owner_type" will be either "Account" or "Ticket". When
retrieving an Account, I want to also return all the Notes associated
with it. I don't care about going the other direction in the
relationship
Is there any way to do this with the Django mappings?
