ember-data-1.0.0 activemodeladapter错误包括传递给“push”的散列中的“id” [英] ember-data-1.0.0 activemodeladapter error include an `id` in a hash passed to `push`

问题描述

我正在使用ember-data和activemodel适配器，后端有rails和mongoid（mongodb）。每当我向我的rails应用程序发出请求时，emberjs显示返回的数据，但在chrome开发者控制台中显示：

 断言失败：你必须在传递给`push`的哈希中包含一个`id` 
  

在一个jsfiddle

我已经重现了这个 的jsfiddle 即可。当我使用 id 代替时，您可以看到不同版本的 jsfiddle 工作的 _id 。

后端发送的有效负载

ActiveModel适配器将snake_case start_date 转换为camel-case。我已经将一些自定义代码添加到ember-data rest-serializer中，以将 _id 转换为 id ，并将代码粘贴到此问题中。

  {schedule：[
 
 {
_id：529f38596170700787000000 ，
name：发型，
start_date：2013-12-12
} 
 
]} 
  

现在，尽管返回的有效载荷包含 id ，如果我进入google cgrome控制台并运行下面的commmands并访问 _data ，它显示 id 未定义。

  a = App .__ container __。lookup（controller：schedule）
b = a.get（'content'）
  

我使用控制台中的公开箭头，深入了解 _dat 对象，这是我看到的

  _data：Object 
 id：undefined 
  

自定义序列化程序代码

我扩展了activemodeladapter将mongodb的_id转换为id，并将其设置为主要k安永。

  App.ApplicationSerializer = DS.ActiveModelSerializer.extend（{
 primaryKey：'_id'，
 
 normalize：function（type，hash，prop）{
 this.normalizeMongoidId（hash）; 
 return this._super（type，hash，prop）; 
}，
 
 normalizeMongoidId：function（hash）{
 var json = {id：hash._id}; 
 delete hash._id; 
 
 //hash.id = hash._id; 
 // delete hash._id; 
} 
 
 / * 
 serialize：function（record，options）{
 var json = this._super（record，options）; 
 
 json.schedule._id = json.record.id; 
 
 delete json.record.id 
 return json; 
} 
 * / 
}）; 
  

ember数据模型：

  App.Schedule = DS.Model.extend（{
 name：DS.attr（'string'），
 organization：DS。 belongsTo（'organization'）
}）; 
  

这是我的emberjs路由器

  App.Router.map（function（）{
 this.resource（'schedule'，{path：/ schedule}，function（） 
 this.resource（'schedule'，{path：/：schedule_id}，function（）{}）; 
 
}）; 
}）; 
  

emberjs路线定位：

  App.SchedulesRoute = Ember.Route.extend（{
 model：function（）{
 return this.store.find（'schedule' ）; 
} 
}）;

解决方案

我有同样的问题。在你的rails serializer中，（假设你有一个），你应该执行

  attributes：id，：name，：start_date 
  

并有一个

在您的日程表串行器中，$ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $让我知道这是否有效。
 
I am using ember-data and the activemodel adapter with rails and mongoid(mongodb) in the backend. Whenever I make a request to my rails app, emberjs displays the returned data but in chrome developer console it displays:
Assertion failed: You must include an `id` in a hash passed to `push` 
the problem reproduced in a jsfiddle

I have reproduced the problem in this jsfiddle. You can see a different version of thesame jsfiddle working when I use id instead of _id.

Payload sent by the backend

ActiveModel adapter converts the snake_case start_date to camel-case. I have added some custom code to ember-data rest-serializer to convert _id to id and that code is pasted lower down in this question. 
    {"schedules":[

       {
         "_id":"529f38596170700787000000",
         "name":"Hair styling",
         "start_date":"2013-12-12"
       }

     ]}
Now though the returned payload includes an id, if I go into the google cgrome console and run the commmands below and access the _data, it shows the id is undefined.
 a = App.__container__.lookup("controller:schedules")
 b = a.get('content')
I f use the disclosure arrows in the console and dig into the _dat object, this is what I see
 _data: Object
   id: undefined
Custom serializer code

I extended the activemodeladapter to convert mongodb's _id to id and to set it as primary key. 
App.ApplicationSerializer = DS.ActiveModelSerializer.extend({
   primaryKey: '_id',

   normalize: function(type, hash, prop) {
      this.normalizeMongoidId(hash);
      return this._super(type, hash, prop);
   },

   normalizeMongoidId: function(hash){
     var json = { id: hash._id };
     delete hash._id;

     //hash.id = hash._id;
     //delete hash._id;
   }

  /*
   serialize: function(record, options){
     var json = this._super(record, options);

      json.schedule._id  = json.record.id;

      delete json.record.id
      return json;
   }
  */ 
}); 
The ember-data model:
App.Schedule = DS.Model.extend({
  name: DS.attr('string'),
  organization: DS.belongsTo('organization')
});
Here is my emberjs router 
App.Router.map(function(){ 
  this.resource('schedules', {path: "/schedules"}, function(){ 
   this.resource('schedule', {path: "/:schedule_id"}, function(){});   

  }); 
});
The emberjs route defination:
 App.SchedulesRoute = Ember.Route.extend({
   model: function(){
    return this.store.find('schedule');  
   }
 });

Thanks
解决方案
I had the same issue. In your rails serializer for schedule, (assuming you have one), you should do
attributes :id, :name, :start_date
and have a
has_many :schedule 
in your SchedulesSerializer. Let me know if this works.
