如果有很多關系，我該如何在炭灰中放置模型？

Question

我從服務器發送的JSON看起來像這樣，

{"selectFill":{"user":[{"userId":"Gru","department":"Villain"},{"userId":"Sulley","department":"Scare"},{"userId":"Popeye","department":"Sailer"}]}}

我的模型看起來像這樣

    App.SelectFill = DS.Model.extend({
    users: DS.hasMany('user',{
        embedded: true
    })
});

App.User = DS.Model.extend({
    userId: DS.attr('string'),
    department: DS.attr('department')
});

App.SelectFillSerializer = DS.WebAPISerializer.extend({
    extractArray: function (store, type, payload, id, requestType) {

        var primaryTypeName = type.typeKey;

        var typeName = primaryTypeName,
            type = store.modelFor(typeName);

        var selectFill = [];
        selectFill.push(payload.selectFill);
        var newi = {};
        newi[typeName] = selectFill;

        return this._super(store, type, newi, id, requestType);
    }
});

我在Chrome調試器中用ember檢查器檢查了代碼，我可以在SelectFill中看到1條記錄，但是它是空的。 用戶記錄也為空。 您能告訴我，我在這里做錯了嗎？我是Ember的新手，我試圖進入Ember源代碼和頭腦，然后我的頭開始旋轉。 每個人都還通過深入研究Ember源代碼來調試其代碼嗎？

您需要將數據轉換為這種格式，並且所有記錄都需要有ID（如果您希望userId為用戶ID，請從模型定義中刪除它並將其添加到適配器中）

{
  "selectFill":
    {
      id:'something',
      "users":['Gru', 'Sulley','Popeye']
    },
  "users":[
    {"userId":"Gru","department":"Villain"},
    {"userId":"Sulley","department":"Scare"},
    {"userId":"Popeye","department":"Sailer"}]
  }

App.UserAdapter = DS....extend({

   primaryKey: 'userId'
});
