My application has two node types: a parent node which can hold recursive child nodes. Think of it like the post-comment system in SO, but comments can be recursive:

parent_1
  child_11
  child_12
    child_121
  child_3
parent_2
  child_21
    child_211
      child_2111

Important to note that the parent nodes have different attributes and behavior than the child nodes.

What is the correct (and presumably most efficient) way of modeling this relationship in Django?
