json - 在 Ember Data 中删除用于 POST/PUT 操作的 JSON 根元素

Question

我正在使用一个在 POST/PUT 动词中需要这样的 JSON 的 Web 服务：

{
    "id":"CACTU",
    "companyName": "Cactus Comidas para llevar",
    "contactName": "Patricio Simpson",
    "contactTitle": "Sales Agent",
    "address": "Cerrito 333",
    "city": "Buenos Aires",
    "postalCode": "1010",
    "country": "Argentina",
    "phone": "(1) 135-5555",
    "fax": "(1) 135-4892"
}

但是 Ember Data 会发送这样的 JSON：

{
    "customer": 
    {
        "id":"CACTU",
        "companyName": "Cactus Comidas para llevar",
        "contactName": "Patricio Simpson",
        "contactTitle": "Sales Agent",
        "address": "Cerrito 333",
        "city": "Buenos Aires",
        "postalCode": "1010",
        "country": "Argentina",
        "phone": "(1) 135-5555",
        "fax": "(1) 135-4892"
    }
}

发送 POST/PUT 操作时如何删除“客户”根元素？

Answer 1

您需要覆盖其中一种序列化方法，我认为 serializeIntoHash 可能有效：

App.CustomerSerializer = DS.RESTSerializer.extend({
  serializeIntoHash: function(hash, type, record, options) {
    Ember.merge(hash, this.serialize(record, options));
  }
});

这不是正常的 serializeIntoHash，看起来像这样：

  serializeIntoHash: function(hash, type, record, options) {
    hash[type.typeKey] = this.serialize(record, options);
  }

可以在此处找到其他文档：
