how to implement promise-based CRUD events?

[hliyan]

from what i understand of the docs, the following adds a single event listener for all update events:

db.addEventListener(['updated'], function(event) {

how do i get a callback for the last update event, or a specific one? i'm trying to wrap YDN with something like this:

mystore.save('users', { name: 'joe' }, 24).then(function(result) {
   // handle something here
});

Dispatching events are expensive and won't emit unless requested during database initialisation.

See installable events section http://dev.yathit.com/ydn-db/doc/setup/events.html

Using events for application logic are not encouraged. There should be better alternative.

just noticed the return type of add(). can i do it this way:

var req = db.add('users', theObject, theId);
req.done = function() {
};
req.fail = function() {
};

looks like i should have looked at the doc closer: http://dev.yathit.com/api/ydn/db/request.html

your request already implements a then(success, fail)

sorry
