使用Ember Dataloading加載

我正試圖擺脫Ember-Data中的一些異步關係，並將它們加載，但卻遇到了一些問題。使用Ember Dataloading加載

我的API發回相關數據，但記錄是返回的每個對象上的屬性，而不是根上的單獨數組/對象。我正在使用extractArray來挖掘數據，所以ED喜歡它，但不能完全正確。下面是從API返回的數據樣本：

{ 
    "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Countries_by_mailingAddressCountry，Currencies_by_currency，並且PaymentTerms_by_paymentTerms出來的對象根。他們到底應該去哪裏？我認爲它應該是：

{ 
    "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ED抱怨說它無法找到相關數據。該模型被定義爲

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, 
});

在您的JSON輸出中是''record''應該是'「vendors」'？ – 2014-12-01 19:31:12

是的，就是這樣。在發佈後找出它。我正在盤旋，以適當的格式更新此問題。我不得不重構我的適配器的大部分，以使sideloading正常工作。 – ultimatemonty 2014-12-01 19:37:47

到底我有我的JSON格式化以下格式

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

一旦我有這個正確格式化和重構我的適配器一切都肉汁！
