uncaught error: assertion failed: error: no model found 'id' 

app.userroute = ember.route.extend({     actions: {         deletetag: function(params) {             this.get('store').find('usertag', params.id).then(function(rec){                 rec.deleterecord();                 rec.save();             });         }     }  });

why ember trying return factory instance of model called "id" ?

thanks!

dumb mistake. error json returned destroy method missing object root.
