Question

我有一个示例笔记本应用程序，可以使用ember-cli的HTTP模拟，也可以使用ActiveModelSerializer跟踪我的rails后端。

当我用ember-fire将它挂钩到firebase时，我能够注册一个用户（我在仪表板中看到它）但是当我尝试通过电子邮件检索它时，我收到以下警告：

WARNING: Encountered "0" in payload, but no model was found for model name "0" (resolved model name using ui@serializer:application:.modelNameFromPayloadKey("0"))

那么这个错误：

Error: Assertion Failed: You must include an 'id' for undefined in an object passed to 'push'
    at new Error (native)
    at Error.EmberError (http://localhost:4200/assets/vendor.js:24735:21)
    at assert (http://localhost:4200/assets/vendor.js:14636:13)
    at Object.assert (http://localhost:4200/assets/vendor.js:22037:34)

    at ember$data$lib$system$store$$Service.extend.push [as _super] (http://localhost:4200/assets/vendor.js:75302:34)
    at push (http://localhost:4200/assets/vendor.js:94940:38)
    at superWrapper [as push] (http://localhost:4200/assets/vendor.js:30984:22)
    at http://localhost:4200/assets/vendor.js:70210:27
    at Object.Backburner.run (http://localhost:4200/assets/vendor.js:9707:25)

我使用以下方式查询商店：

export default Ember.Route.extend({
  actions: {
    login: function() { 
      this.store.query('user', {
        email: this.controller.get('email') 
      }).then((users) => {
        if(users.get('length') === 1) {
          var user = users.objectAt(0); 
          this.controllerFor('application').set('user',user); 
          this.transitionTo('notebooks', user.get('id'));
        }
        else {
          console.log('unexpected query result'); 
        }
     }); 
    }
  } 
});

深入挖掘，我可以通过在finders.js设置断点来看到＃157我即将

store._adapterRun（function（）{ var payload = normalizeResponseHelper（serializer，store，typeClass，adapterPayload，null，'query'）; // TODO优化 records = store.push（payload）; }）;

推送有效载荷。适配器有效负载检查

adapterPayload: Array[1]
   0: Object 
       email: "test@test.com"
       first_name: "Test"
       id: "-K1oINClDw2ylQLww7-p"
       last_name: "User"

这是我的用户。所以除了跟踪之外一切都很好。不确定该ID，但我是firebase的新手;也许没关系。它符合我在仪表板中看到的内容。

我没有对我的序列化器做过任何特别的事 - 它是香草。

import DS from 'ember-data';

export default DS.RESTSerializer.extend({
});

AFAIK我正在使用最新的＆amp;最大的 - 这是bower.json

{
  "name": "ui",
  "dependencies": {
    "ember": "2.1.0",
    "ember-cli-shims": "ember-cli/ember-cli-shims#0.0.4",

    "bootstrap": "~3.3.5",
    "showdown": "~1.3.0",

  }
}

和package.json中的dev依赖项

    "glob": "^4.5.3",

  }

任何指针/帮助/指导都会很棒！我也是新来的，所以也许我错过了显而易见的事情？

您需要从后端返回一个类型键，而不是仅发送一个数组。这让Ember Data知道您推送到商店的模型类型。您的有效负载应如下所示：

users: [
  {
    email: "test@test.com",
    id: "abcdefg"
    (...)
  }
]

而不是

[
  {
    email: "test@test.com",
    id: "abcdefg"
    (...)
  }
]

或者，您可以明确传入类型和数据：

store.push("user", store.normalize("user", response[0]));

（响应仍然是数组）

使用ember-fire获取错误：断言失败：您必须在传递给'push'的对象中包含未定义的'id'
