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.
Tentative categories were assigned with moderate confidence (0.5 to 0.75): they are shown, but they do not count toward a category’s momentum. How categories work
Derived by Crest of Tech from two observations of RubyGems’s own figure, a period apart. Nothing is stored or estimated: without an observation near the period’s start, the period is still collecting.
