If any of them fail ActiveRecord::RecordInvalid gets raised. See ActiveRecord::Validations for more information. There's a series of callbacks associated with save!. If any of the before_* callbacks return false the action is cancelled and save! raises ActiveRecord::RecordNotSaved. See ActiveRecor

reload(options = nil) Instance Public methods Reloads the record from the database.
