Question

我正试图摆脱Ember-Data中的一些异步关系，而不是加载它们，但遇到了一些问题。

我的API会发回相关数据，但记录是返回的每个对象的属性，而不是根目录上的单独数组/对象。我正在使用extractArray来挖掘数据，因此ED喜欢它，但不能完全正确。以下是API返回的数据示例：

{
  "record": [
    {
      "id": 2,
      "name": "3M Aerospace",
      "currency": 6,
      "paymentTerms": 3,
      "Currencies_by_currency": {
        "id": 6,
        "currency": "USD",
        "description": "US Dollar",
        "sortOrder": 1
      },
      "PaymentTerms_by_paymentTerms": {
        "id": 3,
        "term": "NET10",
        "description": "Due with 10 days of invoice date"
        "sortOrder": 3
      }
    },
    {
      "id": 3,
      "name": "BAE Aerospace",
      "currency": 6,
      "paymentTerms": 3,
      "Currencies_by_currency": {
        "id": 6,
        "currency": "USD",
        "description": "US Dollar"
        "sortOrder": 1
      },
      "PaymentTerms_by_paymentTerms": {
        "id": 3,
        "term": "NET10",
        "description": "Due with 10 days of invoice date"
        "sortOrder": 3
      }
    }
  ]
}

我知道我需要从对象根目录中获取Countries_by_mailingAddressCountry，Currencies_by_currency和PaymentTerms_by_paymentTerms。他们到底应该去哪里？我认为应该是：

{
    "record": [
        {
            "id": 2,
            // other data...
            "currency": 6,
            "paymentTerms": 3,
            // more data...
        }, {
            "id": 3,
            // other data...
            "currency": 6,
            "paymentTerms": 3,
            // more data...
        }
    ],
    "currencies": [
        {
            "id": 6,
            "currency": "USD",
            "description": "US Dollar",
            "sortOrder": 1
        }
    ],
    "paymentTerms": [
        {
            "id": 3,
            "term": "NET10",
            "description": "Due with 10 days of invoice date",
            "isActive": true,
            "sortOrder": 3
        }
    ]
}

但是ED抱怨它无法找到相关数据。模型定义为

App.Vendor = DS.Model.extend(App.Addressable, {
    name: DS.attr('string'),
    currency: DS.belongsTo('currency'),
    paymentTerms: Ds.belongsTo('payment-term')
});

App.Currency = DS.Model.extend({
    currency: string,
    description: string,
    sortOrder: number,
});

App.PaymentTerm = DS.Model.extend({
    term: string,
    description: string,
    sortOrder: number,
});

最后我不得不将我的json重新格式化为以下格式

{
    "vendors": [
        // vendor objects
    ],
    "currencies": [
        // currency objects
    ],
    "paymentTerms": [
        // paymentTerms objects
    ]
}

一旦我正确格式化并重构了我的适配器，一切都很好吃！
