kinship

Kinship is a schema-inferred relationship graph for Ruby applications. It automatically discovers parent/child relationships between models by inspecting attributes (e.g. user_id, post_id) and builds a complete in-memory graph with zero configuration. Kinship enables deep relationship traversal, automatic join planning, and eliminates common N+1 query patterns without requiring has_many or belongs_to declarations. It is framework-agnostic and works with Rails, Jetski, and custom ORMs.
