ember.js - model returns null on controller -


i'm working a router , controller, , need complete operations on controller, model code

acornstest.stockroute = ember.route.extend({   model: function(params) {     "use strict";     var url_params = params.slug.split('|'),       url = acornstest.config.quandl.url + '/' + url_params[0] + '/' + url_params[1] + '.json',       stockinstore = this.store.getbyid('stock', url_params[1]),       today =  new date(),       yearago = new date(),       self = this;      yearago.setfullyear(today.getfullyear() - 1);     today = today.getfullyear()+'-'+today.getmonth()+'-'+today.getdate();     yearago = yearago.getfullyear()+'-'+yearago.getmonth()+'-'+yearago.getdate();      if(stockinstore && stockinstore.get('data').length) {       return stockinstore;     }      return ember.$.getjson(url,{ trim_start: yearago, trim_end: today, auth_token: acornstest.config.quandl.apikey })       .then(function(data) {         if(stockinstore) {            return stockinstore.set('data', data.data);         } else {            return self.store.createrecord('stock', {             id: data.code,             source_code: data.source_code,             code: data.code,             name: data.name,             description: data.description,             display_url: data.display_url,             source_name: data.source_name,             data: data.data,             slug: data.source_code+'|'+data.code           });         }     });   } });

and controller

acornstest.stockcontroller = ember.objectcontroller.extend({   init: function() {     "use strict";      this.send('generatechartinfo');   },    actions: {     generatechartinfo: function() {       "use strict";        console.log(this.model);       console.log(this.get('model'));     }   } });

from controller i'm trying access model information , format it, , send view this.model or this.get('model') returns null, how can successful access model controller? thanks

you overriding init method, broken, this:

acornstest.stockcontroller = ember.objectcontroller.extend({   init: function() {     "use strict";     this._super();      this.send('generatechartinfo'); });

you need call parent method.

see test case: http://emberjs.jsbin.com/gijon/3/edit?js,console,output

the model not ready @ init time. if has official docs please share.
