Description:

Ancestry allows the records of a ActiveRecord model to be organized in a tree

  structure, using the materialized path pattern. It exposes the standard

  relations (ancestors, parent, root, children, siblings, descendants)

  and allows them to be fetched in a single query. Additional features include

  named scopes, integrity checking, integrity restoration, arrangement

  of (sub)tree into hashes and different strategies for dealing with orphaned

  records.
