Filtering on a prefetched table

[bamerza]

My model:

var Tracker = persistence.define('Tracker', {

Name: 'TEXT'

});

var TrackerType = persistence.define('TrackerType', {

Name: 'TEXT',

Description: 'TEXT'

});

var TrackerLog = persistence.define('TrackerLog', {

DateOccurred: 'DATE',

TimeofDayId: 'INT',

SeverityId: 'INT',

Saved: 'INT',

Note: 'TEXT'

});

Tracker.hasMany('trackerType', TrackerType, 'tracker');

TrackerType.hasMany('trackerLog', TrackerLog, 'trackerType');

Is it possible to filter on a prefetched table?

I have relational table and want to retrieve a record based on the id of the prefetched table.

e.g., I'd like to do the following but it does not work :

var mtracker = Tracker.all().filter('id', '=', trackerId);

var allLogs = TrackerLog.all().prefetch("trackerType").filter('trackerType.tracker', '=', mtracker);     

If it is possible, in this case would mtracker be the string Id of the record or would it have to be the actual object obtained from a separate query as I did here ?
