Question

我尝试通过mockjax为ember数据建模ajax调用。

我的模特：

App.Service = DS.Model.extend({
  name: DS.attr('string'),
  service_prices: DS.hasMany('servicePrice')
});

App.ServicePrice = DS.Model.extend({
  unit_price: DS.attr('number'),
  qty_unit: DS.belongsTo('qtyUnit'),
  service: DS.belongsTo('service')
});


App.QtyUnit = DS.Model.extend(Ember.Validations.Mixin, {
  name: DS.attr('string'),

});

App.Order = DS.Model.extend({
  service: DS.belongsTo('service'),
  qty_unit:DS.belongsTo('qtyUnit'),
});

我尝试通过order加载mockjax记录。（按下按钮。）根据呼叫后的控制台

MOCK GET: /orders/1 
Object {url: "/orders/1", type: "GET", isLocal: false, global: true, processData: true…}

Ember数据尝试第二次调用

GET http://run.jsbin.com/services/%3CApp.Service:ember518:1%3E 404 (Not Found)

首先，我不会忘记为什么第二次打电话？服务是按我的订单JSON

加载的

var order = {
  "order" : {"id":1,"service":1,"qty_unit":4},
  "service":[{"id":1,"name":"ENG-GER","service_prices":[1,2]}],
  "servicePrices":[
    {"id":1,"qty_unit":4,"unit_price":3},
    {"id":2,"qty_unit":5,"unit_price":4}
  ],
  "qtyUnits":[
    {"id":4,"name":"character"},
    {"id":5,"name":"word"},
    {"id":6,"name":"sentence"}   
  ]
};

为什么尝试使用ember-data调用记录App.Service:ember518:1而不是其id＆＃34; 1＆＃34;？

问题是你的setQtyUnits方法。您正在传递服务模型，而不仅仅是模拟端点所期望的id。在这种情况下，ember518是服务模型实例的ember生成的名称，它被传递而不是id。修改后的方法是 -

setQtyUnits:function(){

        var service_id = this.get('model.order.service.id');
        if (service_id !== null)
        {
          var self = this;
          //find returns a promise
          this.store.find('service',service_id).then(function(service){
            //on success
            var servicePrices = service.get('service_prices');
            var qtyUnits = servicePrices.mapBy('qty_unit');
            console.log(qtyUnits);
            self.set('qtyUnits', qtyUnits);
          });
        } else {
          this.set('qtyUnits', null);  
        }

  }.observes('model.order.service')

Ember数据侧载了mockjax调用
