Shame on me.
This is the right way to do it, the

Hello everyone,
I want to have foreign keys to parent model on a manytomany
intermediate table (through) to have unique entries for that domain.
The problem is i want this parent model class to be an abstract one,
because i don't ever want to inst
First thought is "You haven't provided anywhere near enough context".
Second thought is "That is how it works, so you're doing something
else wrong. See #1".
class PropertyValue(BaseModel):
value = models.CharField(max_length=256)
prop = models.ForeignKey('Property')
parent = models.Foreign
Any thoughts on this?

I have a model with:
parent = ForeignKey('self', blank=True, null=True)
In that model I've overridden clean() to contain:
if self.parent:
# Do some stuff
It raises an attribute error saying that parent.pk doesn't exist. How
can I get around this. Note that my foreign key is recursive.

OK thanks. I didn't realise that was the implication of the
related_name field. All working as expected now.
Thanks, Ben

I have a Thread and a Message model, as defined below:
class Thread(models.Model):
modified = models.DateTimeField(auto_now=True, auto_now_add=True)
class Message(models.Model):
subject = models.CharField(max_length = 100)
thread = models.ForeignKey(Thread, related_name='t
