“findAll的响应必须是Array，而不是未定义” - 潜在错误的序列化？ [英] "The response from a findAll must be an Array, not undefined" - potentially incorrect serialisation?

问题描述

刚开始使用Ember，我正在关注本教程。

Just getting started with Ember, and I'm following this tutorial.

我已经设置了Ember应用程序，路由和模型，除了当我打路线时，我收到大量警告打印到控制台，其次是标题中的错误

I've got the Ember app set up, the Route and the Model, except when I hit the Route, I get a large number of warnings printed to the console, followed by the error in the title.

我的模型看起来像：

App = DS.Model.extend
  firstName: DS.attr('string')
  lastName: DS.attr('string')
  email: DS.attr('string')
  phone: DS.attr('string')
  status: DS.attr('string', defaultValue: 'new')
  notes: DS.attr('string')

我的路线：

App.LeadsRoute = Ember.Route.extend
  model: -> @store.find 'lead'

我的Store.js：

My Store.js:

App.ApplicationStore = DS.Store.extend({

})

# Override the default adapter with the `DS.ActiveModelAdapter` which
# is built to work nicely with the ActiveModel::Serializers gem.
App.ApplicationAdapter = DS.ActiveModelAdapter.extend({

})

JSON我的Rails应用程序返回看起来像这样。

The JSON my Rails app is returning looks like this.

警告是：

WARNING: Encountered "0" in payload, but no model was found for model name "0" (resolved     model name using DS.ActiveModelSerializer.typeForRoot("0"))

（我为数据库中的每个线索收到一个警告）

(I get one warning for each Lead in the Database)

错误是：

Error while processing route: leads Assertion Failed: The response from a findAll must be an Array, not undefined Error: Assertion Failed: The response from a findAll must be an Array, not undefined

这似乎是一个很常见的一个，如果StackOverflow搜索是要做的事情：）

Which seems to be a pretty common one, if StackOverflow search is anything to go by :)

非常感谢！

谢谢，

推荐答案

好吧，所以我想出了这一个...列表响应， -data / ActiveModelAdapter预期的格式如下：

Ok, so I figured this one out... for list responses, ember-data/ActiveModelAdapter is expecting responses formatted like this:

{ "leads" : [ { id: 123, name: "Test", ... }, { id: 456, name: "Test 2", ... } ] }

而我正在发送

[ { "lead": { id: 123, name: "Test", ... } }, { "lead": { id: 456, name: "Test 2", ... }} ] }
