Javascript embedded的embedded data RestAdapter有许多

如何使用余烬数据进行此操作

{"poll":{"id":1,"question":"lym features",
    "choices":[{"id":1,"text":"Improve AI", "PollId":1},
               {"id":2,"text":"Multiplayer","PollId":1},
               {"id":3,"text":"Modern Art","PollId":1}]}}

这是来自服务器的json响应。我需要ember data RESTAdapter来解析它。

我必须重写

DS.RESTSerializer

中的

extractSingle

方法。有关详细信息，请参见代码中的emberjs链接

// http://emberjs.com/api/data/classes/DS.RESTSerializer.html#method_extractSingle
App.PollSerializer = DS.RESTSerializer.extend({
    extractSingle: function(store, type, payload, id) {
        var poll = payload.poll;
        var choices = poll.choices;
        delete poll.choices;

        poll.choices = [];

        choices.forEach(function(c) {
            poll.choices.push(c.id);
        });

        payload = { choices: choices, poll: payload.poll };
        return this._super(store, type, payload, id);
    }
});

这将我的原始结构转换为标准形式

您可以使用EmbeddedRecordsMixin并将
