Instance Method Details

#perform!(failure = false) ⇒ Object

Performs the notification Takes a flag to indicate that a failure has occured. (this is only set from Model#perform! in the event of an error) If this is the case it will set the ‘action’ to :failure. Otherwise, it will set the ‘action’ to either :success or :warning, depending on whether or not any warnings were sent to the Logger. It will then invoke the notify! method with the ‘action’, but only if the proper on_success, on_warning or on_failure flag is true.
