Javascript 余烬数据映射

但在请求数据时，请求成功完成，但我在控制台中遇到以下错误：

未捕获错误：断言失败：服务器返回的哈希值为 关键事件，但您没有它的映射

知道这里出了什么问题吗

===

更新：根据要求，我正在添加更多的Ember.js应用程序

我的重新适应程序设置：

DS.RESTAdapter.registerTransform 'raw',
  deserialize: (serialized) ->
    serialized
  serialize: (deserialized) ->
    deserialized

App.Store = DS.Store.extend
  adapter: DS.RESTAdapter.create
    url: LJ.CONFIG.api.url
  revision: 11
及路线:

App.Router.map ->
  this.resource 'events', ->
    this.route 'new'
  this.resource 'event', path: '/events/:event_id', ->
    this.route 'edit'
  this.resource 'venue', path: '/venues/:venue_id', ->
    this.route 'edit'
    this.resource 'events'
  this.resource 'act', path: '/acts/:act_id', ->
    this.route 'edit'
    this.resource 'events'
  this.route 'search', path: '/search/:term'
  this.route 'doc', path: '/docs/:doc'
乍一看，反应似乎很完美

我的猜测是，您发送了错误请求的错误格式

此格式对许多
事件有效，这意味着
findAll
或
findQuery
（
GET/events
）

但是，如果为单个
find
（
get/events/5118dd8c4c80866ef2000051）返回此响应，则可能会出现此错误

在这种情况下（当您仅获取一个
事件时），您的响应应该如下所示：


{ 
    "events": [
        {
            "id": "5118dd8c4c80866ef2000051",
            "title": null,
            "starts_at": 1361901600,
            "ends_at": null,
            "currency": "SEK",
            "cents_door": 4000,
            "cents_advance": null,
            "price_door": "40.00 kr",
            "price_advance": null,
            "age_limit": null,
            "venue_section": "PLAYHOUSE",
            "description": null,
            "url": null,
            "repeats": null,
            "repeats_until": null,
            "venue_id": "nefertiti-jazz-club",
            "act_ids": [ "marias-playhouse" ]
        }
    ]
}

经过大量调试和搜索，Ember.js似乎还不支持查询字符串参数。我不得不像这样修改我的路线：


{ 
    "events": [
        {
            "id": "5118dd8c4c80866ef2000051",
            "title": null,
            "starts_at": 1361901600,
            "ends_at": null,
            "currency": "SEK",
            "cents_door": 4000,
            "cents_advance": null,
            "price_door": "40.00 kr",
            "price_advance": null,
            "age_limit": null,
            "venue_section": "PLAYHOUSE",
            "description": null,
            "url": null,
            "repeats": null,
            "repeats_until": null,
            "venue_id": "nefertiti-jazz-club",
            "act_ids": [ "marias-playhouse" ]
        }
    ]
}

  url: DS.attr('string')
  repeats: DS.attr('string')
  repeatsUntil: DS.attr('string')
  venue: DS.belongsTo('App.Venue')
  acts: DS.hasMany('App.Act')



{
  "event": {
    "id": "5118dd8c4c80866ef2000051",
    "title": null,
    // ... rest of attributes
  }
}

这远非十全十美，但它目前仍在发挥作用。显然，查询字符串支持计划在不久的将来发布。
这是正确的格式。在“events”键下返回多个事件，在“event”键下只返回一个事件。余烬和余烬数据可以很好地用于单个事件。它只是在这个有多个事件的路由上，它抛出了这个错误。返回上述响应的请求的URL是什么？它还没有公开，但URL看起来像：
http://lj-web.dev/#/events/?location=goteborg-瑞典vastra gotaland county&origin=57.704123999999%2C11.9788316
。返回了正确的API响应，但ember数据似乎不喜欢它…响应格式与请求非常相关，这就是我询问请求的原因。。。您使用
App.Event.find（{..}）
发出请求？我只是使用默认的余烬行为。我还没有为此编写任何特定的代码。我应该吗？沃特？你能纠正一下语法并进一步解释一下吗？这是否仍然相关？
