Multiple references to same field

Hi,

I am wondering if I can dynamically add multiple references to a same field in a django model. Let's say I have this model:

class Entry(models.Model)

    parent = models.ForeignKey('Entry', null = True, related_name = 'children')

    ...

entry = Entry.objects.get(id=0)

Now, I want entry.post to be entry.parent. But I also want to be able to filter by the "virtual" field post. Say Entry.objects.get(post__id__in=[something])

Is this possible at all?

Thanks and cheers!
