Instance Method Details

#events(action) ⇒ Object

the events method is a developer's tool for visualizing the event order for a given card. For example, from a console you might run

puts mycard.events :update

to see the order of events that will be executed on mycard. The indention and arrows (^v) indicate event dependencies.

Note: as of yet, the functionality is a bit rough. It does not display events that are called directly from within other events, and certain event requirements (like the presence of a 'current_act') may prevent events from showing up in the tree.
