This gem extends ActiveRecord to add additional functionality to JSONB - use PostgreSQL JSONB data for associations - thread-safe single-key updates to JSONB columns using `jsonb_set` - extended `table#references` for easy migrations and indexes - virtual JSONB foreign keys using check constraints (NOTE: real foreign key constraints are not possible with PostgreSQL JSONB) Inspired by activerecord-jsonb-associations, but for use in Rails 6+ and ruby 2.7+ and with some unnecessary options and features (HABTM) removed and some additional features added
