ember.js - In Ember Data how do I set a relationship field by id without it sending null to the server? -

i have order model

export default ds.model.extend({   account: ds.belongsto('account', {async: true}),   address: ds.belongsto('address', {async: true}),   orderitems: ds.hasmany('orderitem', {async: true}),   orderstatus: ds.belongsto('orderstatus', {async: true}),   specialinstructions: ds.attr('string'),   creationdate: ds.attr('date') }); 

this has order status, has model:

export default ds.model.extend({   value: ds.attr('string'),   orders: ds.hasmany('order', {async: true}) }); 

in order/create route use model account , aftermodel create new order in db straight away. want create in aftermodel this:

var order = this.store.createrecord('order', {   account: model,   orderstatus: 1 });  return ember.rsvp.hash({   order: order.save().then(function() {     self.set('order', order);   }),   products: this.store.findall('product').then(function(result) {     self.set('products', result);   }) }); 

but looking @ post server ember sending orderstatus: null server.

in addition want set again later in saveorder action (on controller).

order.set('orderstatus', 3); order.save().then(function() {     self.transitiontoroute('member.orders', order.get('account')); }); 

can way? have components want send actions save objects (looking towards ember 2.0), setting id's ideal won't want access store in component etc.
