Ancestry is a gem that allows the records of a Ruby on Rails ActiveRecord model to be organized as a tree structure (or hierarchy). It employs the materialized path pattern and exposes all the standard tree structure relations (ancestors, parent, root, children, siblings, descendants), allowing all of them to be fetched in a single SQL query. 3,136 stars by now
