Creating an unlimited forum hierarchy in Django

Question

I\'m trying to design models for a forum I wish to create in Django.

So far I have:

class Forum(models.Model):
    name = models.CharFie         


        

Answer 1

I would simply create one Forum model that can either have another Forum as it's parent, or have a null parent. Then if you want to print out all parents you could use a while loop like this pseudocode:

heirarchy = ""
f = this forum model
while f.parent is not null:
   heirarchy.append(f.parent.name)
   f = f.parent

to answer the other part of your question, in order to select a child while knowing the parent id, you would query Django's object structure like so:

Forum.objects.filter(parent=PARENT_ID)

and to get the grandparent of a child you would do:

forum_object.parent.parent
