我正在尝试按照http://emberjs.com/guides/models/connecting-to-an-http-server/使用 ember 数据，但是在创建其余 api 之后，我收到了 js 错误，例如：

加载路线时出错：

类型错误：数据未定义

关于代码：

Ember.assert("你必须id在传递给push", data.id != null);

我最初认为我需要在我创建的模型中包含“id”字段，但如果我这样做，它会引发错误，说我不应该将 id 字段放入模型中。其余 API 的输出是正确的：

{
"analyticsRun": {
    "id": 1,
    "analyticsPlan": "some plan",
    "commandScript": "some script",
    "analyticsRunParameters": [
        "homeDir",
        "historyDir",
        "Sourcefolder",
        "resultsDir",
        "dataDir"
    ]
},
"analyticsRunParameters": [
    {
        "id": "homeDir",
        "default": "Some default",
        "description": "Where is the analytics folder",
        "name": "homeDir",
        "value": "Q:/Ember",
        "type": "global"
    },
    {
        "id": "historyDir",
        "default": "Rhistory",
        "description": "Where R image will be saved",
        "name": "historyDir",
        "value": "Rhistory",
        "type": "global"
    },
    {
        "id": "Sourcefolder",
        "default": "J:/Analytics_R_Source_Scripts",
        "description": "Where are source codes and functions are saved",
        "name": "Sourcefolder",
        "value": "J:/_R_Source_Scripts",
        "type": "type 1"
    },
    {
        "id": "resultsDir",
        "default": "results",
        "description": "Where are results stored",
        "name": "resultsDir",
        "value": "results",
        "type": "global"
    },
    {
        "id": "dataDir",
        "default": "Export",
        "description": "Where is raw csv stored",
        "name": "dataDir",
        "value": "Export",
        "type": "global"
    }
]
}

我的模型定义为：

AS.AnalyticsRun = DS.Model.extend({
'analyticsPlan' : DS.attr('string'),
'commandScript' : DS.attr('string'),
'parameters'    : DS.hasMany('analyticsRunParameter')
});

AS.AnalyticsRunParameter = DS.Model.extend({
'name'          : DS.attr('string'),
'type'          : DS.attr('string'),
'description'   : DS.attr('string'),
'default'       : DS.attr('string'),
'value'         : DS.attr('string')
});

我的路线是：

AS.AnalyticsConfigRoute = Ember.Route.extend({
model: function(param) {
    var store = this.get('store');
    return store.find('AnalyticsRun',param.runId);
}
});

从错误看来，代码正在执行 id 查找但未能找到它。以前有没有人遇到过这个问题，或者您对如何解决这个问题有任何建议？

注意：isuse 似乎是在 _find 函数中的 ember-data.js 文件中引起的。

return resolve(promise).then(function(payload) {
Ember.assert("You made a request for a " + type.typeKey + " with id " + id + ", but the      adapter's response did not have any data", payload);
//payload has data here
payload = serializer.extract(store, type, payload, id, 'find');
//payload is undefined here!!
return store.push(type, payload);
}

谢谢，迪

好的，所以我正在设置一个 JSBIn，在那之前我会继续寻找问题（我对 Ember 模型更加熟悉）。

您是否尝试在查找时将 analyticsRun 设置为小写？

 model: function(param) {
   var store = this.get('store');
   return store.find('analyticsRun',param.runId);
 }
