将 JSON 转换为适合 RESTAdapter EmberJS 的格式 [英] Transform JSON to an appropriate format for RESTAdapter EmberJS

问题描述

我从我们的 API 收到一个 JSON 格式如下

<预><代码>[{身份证":45，"name": "意大利面","_order": 0,is_hidden":空，is_list":假},{身份证":46，"name": "沙拉","_order": 1,is_hidden":空，is_list":假},{身份证":47，"name": "甜点","_order": 2,is_hidden":空，is_list":假}];

我发现标准 RESTAdapter 的格式无效，我需要先输入模型的名称.在我的例子中，它可能应该是这样的:

<代码>{类别":[{身份证":45，"name": "意大利面","_order": 0,is_hidden":空，is_list":假},{身份证":46，"name": "沙拉","_order": 1,is_hidden":空，is_list":假},{身份证":47，"name": "甜点","_order": 2,is_hidden":空，is_list":假}]}

那么如何使它在我的适配器中看起来像这样呢?看起来我应该使用 DS.RESTSerializer，但我不知道我应该覆盖哪个方法......

解决方案

我今天早些时候遇到了这个问题.一个很好的干净的修复方法是定义一个您的 ApplicationSerializer 的 normalizePayload 方法.它已被覆盖，因此您不会影响其他任何东西.

例如

App.ApplicationSerializer = DS.RESTSerializer.extend({normalizePayload:函数(类型，有效载荷){返回{类别:有效载荷}；}}

如果您只想对处理的部分有效负载执行此操作，则只需在其中添加条件即可.

App.ApplicationSerializer = DS.RESTSerializer.extend({normalizePayload:函数(类型，有效载荷){if (type.toString() === 'App.Category') {返回{类别:有效载荷}；}}}

I receive a JSON from our API that has the following format

[
  {
    "id": 45,
    "name": "Pasta",
    "_order": 0,
    "is_hidden": null,
    "is_list": false
  },
  {
    "id": 46,
    "name": "Salads",
    "_order": 1,
    "is_hidden": null,
    "is_list": false
  },
  {
    "id": 47,
    "name": "Dessert",
    "_order": 2,
    "is_hidden": null,
    "is_list": false
  }
];

I see that it has invalid format for standard RESTAdapter and I need to put the name of the model first. In my example it should probably be like:

{
  "category":
    [
      {
        "id": 45,
        "name": "Pasta",
        "_order": 0,
        "is_hidden": null,
        "is_list": false
      },
      {
        "id": 46,
        "name": "Salads",
        "_order": 1,
        "is_hidden": null,
        "is_list": false
      },
      {
        "id": 47,
        "name": "Dessert",
        "_order": 2,
        "is_hidden": null,
        "is_list": false
      }
    ]
  }

So how to make it look this way in my adapter? It seems like I should use DS.RESTSerializer, but I can't figure out which method I should override...

解决方案

I ran into this issue earlier today. A nice clean way to fix it is to define a normalizePayload method for your ApplicationSerializer. It's made to be overwritten, so you aren't affecting anything else.

E.g.

App.ApplicationSerializer = DS.RESTSerializer.extend({
    normalizePayload: function(type, payload) {
        return { category: payload };
    }
}

If you want to do this on only some of the payloads processed then you just add a conditional inside it.

App.ApplicationSerializer = DS.RESTSerializer.extend({
    normalizePayload: function(type, payload) {
        if (type.toString() === 'App.Category') {
            return { category: payload };
        }
    }
}
