Question

考虑这种关系：

Office ->hasMany rooms -> hasMany tables -> hasMany drawers

以JSONAPI格式表示如下：

考虑以下关系：

官方 - ＆gt;拥有多个房间 - ＆gt; hasMany表 - ＆gt;有很多抽屉

由以下JSON代表：

  "data": [{
    "type": "office",
    "id": 201,
    "attributes": {
      "owner": 5,
       ......
      "total-rooms": 1,

    },
    "links": {
      "self": "/offices/201",
    },
    "relationships": {

      "rooms": {
        "links": {
          "self": "/offices/201/relationships/rooms",
          "related": "/offices/201/rooms"

        },
        "data":[
          { "type": "room", "id": 201 },

        ]
      }
    }
  }],
  "included": [ {
    "type":"room",
    "id": 201,
    "attributes": {
      "office": 5,
      "some-property": "Test Property tpo see if it works"
    },
    "links": {
      "self": "/offices/5/rooms/201",

    },
    "relationships": {
      "tables": {
        "links": {
          "self": "/offices/5/rooms/201/relationships/rooms",
          "related": "/offices/5/rooms/201/tables",

        },
        "data":[
          { "type": "tables", "id": 801 },

        ]
      }
    }

  },{
      "type":"tables",
      "id": 801,
      "attributes": {
        "room": 201,
        "table-test-data":"Some test data",


      },
      "links": {
        "self": "/offices/5/rooms/201/tables/801",
      },
      "relationships": {
      "drawers": {
        "links": {
          "self": "/offices/5/rooms/201/tables/810/relationships/drawers",
          "related": "/properties/5/rooms/201/tables/810/drawers",

        },
        "data":[
          { "type": "drawer", "id": 1001 },

        ]
      }
    }

    },


  ]

}

我尝试使用以下型号在EmberJS / Ember数据中对它们进行建模：

//Office
export default DS.Model.extend({
    totalRooms: DS.attr('number');
    rooms: DS.hasMany('room');
});

//Rooms
export default DS.Model.extend({
    total: DS.attr('number');
    tables: DS.hasMany('table');
});

//Table
export default DS.Model.extend({
    totalTables: DS.attr('number');
    drawers: DS.hasMany('drawer');
});
//Drawer
export default DS.Model.extend({
    totalDrawers: DS.attr('number');
    drawers: DS.attr('string')
});

但是，Ember数据仅加载主数据的第一级关系。也就是说，在我的控制器中，当我执行以下操作时：

model.offices.forEach(function(office) {
    office.rooms.forEach(function(room){
        //Can access room properties

        // cannot access tables
        console.log(room.tables); //prints a class instead of object

    })

})

我可以访问房间的所有数据，但是当我尝试更深入一级时，例如表格是未定义的。我不想使用多个调用来加载数据，并且想知道我是否遗漏了服务器返回的JSON中的内容，或者我需要以不同的方式处理它？</ p>

非常感谢任何帮助。
