ember数据没有找到属性名称的模型

Question

我已经定义了一个模型(app/models/job.js)

import DS from 'ember-data';

export default DS.Model.extend({
    status: DS.attr(),
    result: DS.attr()
});

我试图从索引控制器(app/controllers/index.js)加载它

import Ember from 'ember';

export default Ember.Controller.extend({
    productName: "",
    customerName: "",
    startDate: "",
    endDate: "",
    actions: {
        search: function() {
            let data = this.store.find("job", '9e5ce869-89b3-4bfc-a70f-034593c21eae');
            return data;
        }
    }
});

我得到的HTTP响应是:

{
    "status": "OK",
    "result": {
        "b": 2,
        "a": 2,
        "see": 1,
        "c": 1
    }
}

我怎么得到以下错误和警告:

WARNING: Encountered "status" in payload, but no model was found for model name "status" (resolved model name using next-gen-analytics@serializer:job:.modelNameFromPayloadKey("status"))
WARNING: Encountered "result" in payload, but no model was found for model name "result" (resolved model name using next-gen-analytics@serializer:job:.modelNameFromPayloadKey("result"))

任何建议将不胜感激

更新 我认为这是一个错误,所以我继续记录一个关于ember-data github repo的错误,在一小时左右得到@wecc的响应(NICE) https://github.com/emberjs/数据/问题/ 3683

所以为了解决这个问题,我编写了自己的序列化程序.

import DS from 'ember-data';

export default DS.RESTSerializer.extend({
normalizePayload: function(payload) {
    return {
        'job': {
            id: '9e5ce869-89b3-4bfc-a70f-034593c21eae',
            status: payload.status,
            result: payload.result
        }
    };

}
});

现在,它开始工作了.

观点我可以想到他们为什么以这种方式实现默认的RESTSerializer,但我们可能应该向用户提供有关ember-data文档的更多信息,否则,尝试使用它的新手会迷路.

1)您的服务器响应应该具有与模型相同名称的根元素.因此,对于单个对象,它应该是:

{
    "job": {
        "id": "<backend must provide an id, integer preferred>"
        "status": "OK",
        "result": {
            "b": 2,
            "a": 2,
            "see": 1,
            "c": 1
        }
}

对于多个对象:

{
    "jobs": [{
        "id": "<backend must provide an id, integer preferred>"
        "status": "OK",
        "result": {
            "b": 2,
            "a": 2,
            "see": 1,
            "c": 1
        }, {/*next object*/}]
}
