ember.js - How to access computed properties in a child controller from a parent resource -

say have routes like

app.router.map(function() {     this.resource('month', { path: '/:month_id' }, function() {         this.route('summary');     }); }); 

i think /:month_id/summary route, default model/controller same /:month_id route, i'd have access correct month model , computed properties added monthscontroller. instead, find have add code:

app.monthsummaryroute = ember.route.extend({     model: function() {         return this.modelfor("month");     } });  app.monthsummarycontroller = ember.objectcontroller.extend({      needs: ['month'] }); 

this seems lot urls point same data, since plan on making many child urls of resource sharing data.

is there better way this? want make sure i'm dong right way.

i guess since using needs api correct , recommended way share data beetween controllers on right track.

hope helps.
