Ember数据:在JSON有效负载上使用"链接"以获取hasMany关系

Question

使用DS.RESTAdapter在应用程序中给出两个模型:

App.Calendar = DS.Model.extend({
  reservations: DS.hasMany("reservation", { async: true })
});

App.Reservation = DS.Model.extend({
  date: DS.attr("date"),
  calendar: DS.belongsTo("calendar")
});

和有效载荷如:

/ API /日历/ 1:

{
  "calendar": {
     "id": 1,
     "reservations": [],
     "links": {
        "reservations": "/api/calendar/1/reservations"
     }
  }
}

/ API /日历/ 1 /保留:

{
  "reservations": [
     {
        "id": 1,
        "date": "10/01/2014"
     }
  ]
}

为什么Calendar模型上的预留数组没有延迟加载？

Answer 1

您的 json 不应定义两次保留

{
  "calendar": {
     "id": 1,
     "links": {
        "reservations": "/api/calendar/1/reservations"
     }
  }
}
