GORM Inside And Out
summary
GORM claims to give Hibernate‑level ORM power with far less config by treating classes under grails-app/domain as persistent, adding methods like addToX/removeFromX, and auto‑providing id, save (which validates and returns null on failure) and dynamic finders. It demos how dbCreate modes (create/drop/update), schema export and mapping blocks control schema, and shows a tiny runtime methodMissing prototype that builds SQL from finder names — the prototype works and mirrors GORM’s approach.
