Adding foreign key to User model

[triman]

I'm sure there is an easy way to do this, but I can't seem to make it
work.  I need to add a couple foreign key references to the User model
(defined in the admin application).   I've imported the admin User,
but it still fails to resolve it.  Does it need to refered to it by
it's full class name?

from django.contrib.auth.models import User
class Ticket(models.Model):
created_by = models.ForeignKey("User",
related_name="created_by_user_id")
assigned_to = models.ForeignKey("User",
related_name="assigned_to_user_id")

Any help would be appreciated

Custom linking of models in many-to-one relationship

[triman]

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?
