Example: + + transaction do |transaction| + david.withdrawal(100) + mary.deposit(100) + transaction.rollback! # rolls back the transaction that was otherwise going to be successful + end + * Made increment_counter/decrement_counter play nicely with optimistic locking, and added a more general update_counters method [Jamis Buck] * Reworked David's query cache to be available as Model.cache {...}. For the duration of the block no select query should be run more then once. Any inserts/deletes/executes will flush the whole cache however [Tobias Luetke] |
