Mirage的Emberjs无法完全填充记录

我有一个带有mirage和serialializer的ember模型。当我在模型中添加一些新字段时，尽管处于有效载荷中，但它们从未被人口填充：

serializers/application.js

....
normalizeArrayResponse(store, primaryModelClass, payload, id, requestType) {
        const payloadTemp = {};
        const rootKey = Ember.String.pluralize(primaryModelClass.modelName);
    payload.properties.forEach((property, index) => {
    //  in here, property["property_type"] returns the correct value based off 
     ///the fixtures in mirage. Afterwards, property.get("property_type") is  always undefined
            payload.properties[index].featured_image = property["embedded"]["wp:featuredmedia"]
    });
        //payloadTemp[rootKey] = payload;
        return this._super(store, primaryModelClass, payload, id, requestType);
    },

models/property.js

export default Model.extend({
  date: attr('date'),
  slug: attr('string'),
  title: attr(),
  excerpt: attr(),
  department: attr('string'),
  latitude: attr('string'),
  address_street: attr('string'),
  address_two: attr('string'),
  address_three: attr('string'),
  address_four: attr('string'),
  address_postcode: attr('string'),
  features: attr('string'),
  feature_1: attr('string'), //new
  feature_2: attr('string'), //new
  feature_3: attr('string'), //new
  feature_4: attr('string'),  //new
  longitude: attr('string'),
  price: attr('string'),
  price_formatted: attr('string'),
  currency: attr('string'),
  tenure: attr('string'),
  property_type: attr('string'), //new
  bedrooms: attr('string'),
  bathrooms: attr('string'),
  parking: attr('string'),
  reception_rooms: attr('string'),
  featured_image: attr()
});

在normalizeArrayResponse函数中，检查payload.properties.forEach循环中是否存在property.property_type，但是一旦成为记录，它首次创建了模型后添加的字段(例如，用//new突出显示始终未定义(例如，property.get('property_type')(。p>

我假设您的 mirage/serializers/application.js 正在使用restSerializer，

import { RestSerializer } from 'ember-cli-mirage';
export default RestSerializer.extend({});

因此，请确保您在 app/serializers/application.js。

中扩展了 DS.RESTSerializer

响应数据正在删除_，并使其基于骆驼键。因此，如果您定义了property_type，那么Mirage正在用propertyType响应它，以相同的方式使所有数据与RESTSERIALIAMER格式保持一致，请查看此

console.log({"id":"20829","date":"2017-05-22T16:31:42","dateGmt":"2017-05-22T16:31:42","guid":{"rendered":"http://www.example-estates.co.uk/property/goldstone-crescent-dunstable/"},"modified":"2017-05-25T16:00:04","modifiedGmt":"2017-05-25T16:00:04","slug":"goldstone-crescent-dunstable","status":"publish","type":"property","link":"http://www.example-estates.co.uk/property/goldstone-crescent-dunstable/","title":{"rendered":"Goldstone 2 Crescent DUNSTABLE"},"excerpt":{"rendered":"<p>NO UPPER CHAIN &#8211; A THREE BEDROOM EXTENDED SEMI DETACHED HOUSE LOCATED TO THE EAST OF TOWN THAT FEATURES, CLOAK/SHOWER ROOM, UTILITY ROOM/STUDY, LANDSCAPED GARDENS AND GARAGE WITH AMPLE PARKING.</p>n","protected":false},"template":"","department":"residential-sales","addressStreet":"","addressTwo":"","addressThree":"Dunstable","addressFour":"","addressPostcode":"LU5 4QU","latitude":"51.8936687","longitude":"-0.5047035","price":"325000.00","priceFormatted":"&pound;325,000","currency":"","priceQualifier":"","saleBy":"","tenure":"Freehold","deposit":"","furnished":"","availableDate":"","bedrooms":"3","bathrooms":"","receptionRooms":"1","propertyType":"Semi-Detached House","parking":"Garage and Driveway, Parking For 2 Cars","outsideSpace":"","featured":"","availability":"For Sale","marketingFlags":"","features":["NO UPPER CHAIN","A THREE BEDROOM EXTENDED","SEMI DETACHED HOUSE","LOCATED TO THE EAST OF TOWN","CLOAK/SHOWER ROOM","UTILITY ROOM/STUDY","LANDSCAPED GARDENS","GARAGE WITH AMPLE PARKING","GAS FIRED CENTRAL HEATING","DOUBLE GLAZING"],"feature1":"A THREE BEDROOM EXTENDED","feature2":"SEMI DETACHED HOUSE","feature3":"LOCATED TO THE EAST OF TOWN","feature4":"CLOAK/SHOWER ROOM","description":"<p class="room">ACCOMMODATION COMPRISES: Etended entrance hall, utility/study, cloak/shower room, large kitchen/dining room, large lounge to the rear of the property overlooking landscaped private garden, large landing with three generous bedrooms and bathroom, driveway, ample parking and gardens.n                </p>n                ","office":{"name":"Dunstable Office","address":"20 West Street Dunstable Bedfordshire, LU6 1SX","telephone_number":"01582 661112","email_address":"sales@example-estates.co.uk"}});

payload.properties[0].property是普通对象，它没有get方法，因此property.get("property_type")这将显示.get is not function错误。
您可以直接操纵payload并将其返回。您无需介绍tempPayload。

    从" ember"进口余烬；    从" ember-data"导入ds；    导出默认ds.restserializer.extend({{        normalizearrayResponse(商店，主要模块级，有效载荷，ID，requestType({            payload.properties.foreach((属性，索引(=> {                属性['farmit_image'] ="新值";            }(;            返回this._super(存储，primarymodelClass，有效载荷，ID，requestType(;        }    }(;

您是否尝试使用normalize而不是normalizeArrayResponse？我用它添加了一些属性，对我来说很好。顺便说一句，您确定需要在序列化器中修改有效载荷吗？我建议仅当您无法控制后端时才这样做。否则，最好修改后端与Ed兼容。

另外，在您的代码中，我发现您正在尝试为featured_image分配property["embedded"]["wp:featuredmedia"]的值。但是我没有在您的固定装置中看到这样的属性。这可能导致致命错误，这可能中断normalizeArrayResponse方法的执行。我建议检查浏览器控制台是否有错误并检查您的固定装置。
