Module callbacks 

Active Record-style lifecycle callbacks.

A model implements Callbacks (all hooks default to no-op) and persists through run_create/run_update/run_destroy, which fire the hooks in Rails’ order around the supplied persistence step. A hook returning Err aborts before the record is written.
