I was wondering if anyone has made a field for managing hierarchical
data in Django?
For example, a TreeField that manages "parent" relationships and gives
the model parent and children object managers:
class Category(model.Model):
tree = TreeField()
>>> a = Category()
>>> b = Category()
>>> c = Category()
>>> b.tree.parent = a
>>> c.tree.parent = a
>>> a.tree.children.all()
[b, c]
