arboreal 0.0.1
Arboreal is yet another extension to ActiveRecord to support tree-shaped data structures. Internally, Arboreal maintains a computed "ancestry_string" column, which caches the path from the root of a tree to each node, allowing efficient retrieval of both ancestors and descendants. Arboreal surfaces relationships within the tree like +children+, +ancestors+, +descendants+, and +siblings+ as scopes, so that additional filtering/pagination can be performed.
