Ember.js - Error - “Assertion failed：您必须在传递给”push“的散列中包含一个”id“ [英] Ember.js - Error - "Assertion failed: You must include an `id` in a hash passed to `push`"

问题描述

通过使用Express编写的REST API将文档（标题，文本）保存到mongodb数据库后，我收到此错误，并刷新浏览器。我已经将主键设置为_id，并且已经阅读了可能正常化数据？

这是服务器的有效载荷（只有1个帖子，以db为单位）：

_id：52c22892381e452d1d000010，
__v：0 
} 
] 
} 
  / pre> 
 
 
控制器：
  App.PostsController = Ember。 ArrayController.extend（{
 actions：{
 createPost：function（）{
 // Dummy content for now 
 var to_post = this.store.createRecord（'post'，{ 
标题：'标题'，
文本：'Lorem ipsum'
}）; 
 to_post.save（）; 
} 
} 
}）; 
  
模型：
  App.Post = DS.Model.extend（{
 title：DS.attr（'string'），
 text：DS.attr（'string'）
 }）; 
  
序列化器：
 code> App.MySerializer = DS.RESTSerializer.extend（{
 primaryKey：function（type）{
 return'_id'; 
} 
}）; 
  
适配器：
 code> App.ApplicationAdapter = DS.RESTAdapter.extend（{
 namespace：'api'
}）; 
  
任何帮助都非常感谢！如果您需要任何其他信息，请通知我。

使用自定义适配器/序列化器时，命名很重要。如果要将其应用于整个应用程序，应该称为 ApplicationSerializer  
  App.ApplicationSerializer = DS.RESTSerializer.extend（{
 primaryKey：'_id'
}）; 
  
适配器：
 code> App.ApplicationAdapter = DS.RESTAdapter.extend（{
 namespace：'api'
}）; 
  
如果您只想将其应用于单个模型（这适用于适配器） p> 
 
 
  App.PostSerializer = DS.RESTSerializer.extend（{
 primaryKey：'_id'
}）; 
  
 
I'm getting this error after I save a post (title, text) to a mongodb database via a REST API written with Express and refresh the browser. I've already set my primary key to '_id' and have been reading about possibly normalizing the data? 

Here is the payload from the server (only 1 post in db):
{
  "posts": [
  {
    "title": "The Title",
    "text": "Lorem ipsum",
    "_id": "52c22892381e452d1d000010",
    "__v": 0
   }
  ]
}
The controller:
App.PostsController = Ember.ArrayController.extend({
    actions: {
      createPost: function() {
        // Dummy content for now
        var to_post = this.store.createRecord('post', {
          title: 'The Title',
          text: 'Lorem ipsum'
        });
        to_post.save();
      }
    } 
 });
The model:
App.Post = DS.Model.extend({
   title: DS.attr('string'),
   text: DS.attr('string')
});
Serializer:
App.MySerializer = DS.RESTSerializer.extend({
  primaryKey: function(type){
    return '_id';
  }
});
Adapter:
App.ApplicationAdapter = DS.RESTAdapter.extend({
  namespace: 'api'
});
Any help is much appreciated! Please let me know if you need any other info.
Thanks

When using custom adapters/serializers the naming is important.  If you want it to apply to the entire application it should be called ApplicationSerializer
App.ApplicationSerializer = DS.RESTSerializer.extend({
  primaryKey: '_id'
});
Adapter:
App.ApplicationAdapter = DS.RESTAdapter.extend({
  namespace: 'api'
});
If you just want it to apply to a single model (this applies to adapter's as well)
App.PostSerializer = DS.RESTSerializer.extend({
  primaryKey: '_id'
});
