The database layer can do this easily, so harness its power! Put a foreign key constraint in your DB with ON DELETE RESTRICT. The Railsy way to do this is with the excellent foreign_key_migrations plugin (see http://github.com/harukizaemon ) -- which you should probably be using in any case. It works with mySQL and PostgreSQL; I'm not sure about other database systems.
