Instance Method Details

#abort(status, msg = 'action canceled') ⇒ Object

The Card#abort method is for cleanly exiting an action without continuing to process any further events.

Three statuses are supported:

failure: adds an error, returns false on save
success: no error, returns true on save
triumph: similar to success, but if called on a subcard
         it causes the entire action to abort (not just the subcard)

Raises:
