ember数据有很多关系

Question

http://jsbin.com/EveQOke/150/edit

我的有效载荷如下所示：

var customers = {
  "customers":[
    {"id":3,"name":"Joe","bio":"some tex","contact":"NY"},
    {"id":2,"name":"Rox","bio":"mo' tex","contact":"LA"}
  ]
};

var orders = {
  "orders":[
    {"id":1,"customer":3,"amount":20},
    {"id":2,"customer":3,"amount":60}
  ]
};

显然它不会工作，所以我有一个串行器http://mozmonkey.com/2013/12/loading-json-with-embedded-records-into-ember-data-1-0-0-beta/到目前为止工作得很好，为很多关系付出了代价。

ember的商店是否有可能自动检测两种型号的关系？还是必须嵌入？
