Ember-data 一直说“没有找到 mdel”

Question

我正在尝试使用 Ember-Data 编写一个 EMberjs 应用程序。还有，require.js 和 coffeescript。尽管遵循了我能找到的每一个指南和讨论，我仍然收到“找不到模型”错误。

这是我的课程：

main.coffee（require.js 的入口点）：

require.config
  paths:
    jQuery:     "../javascript/jquery-2.1.1.min"
    handlebars: "../javascript/handlebars-v1.3.0"
    ember:      "../javascript/ember.prod"
    ember_data: "../javascript/ember-data.prod",
  shim:
    ember:
         deps: ["jQuery", "handlebars"]
         exports: "Ember"
    'ember_data':
      deps:[ 'ember'],
      exports:'DS'

require ["app", "router"], (app, Router) ->
  app.deferReadiness()
  Router()
  app.advanceReadiness()
  return

app.coffee：

define "app", ["ember", "ember_data"], (Ember) ->
  window.app = Ember.Application.create()
  app.ApplicationAdapter = DS.FixtureAdapter.extend()
  app

router.coffee：

define "router", ["app", "ember-data", "ember", "models/person"], (app) ->
  ->         
    app.Router.map -> 
      @route 'home', path: "/"
      @resource('person', { path: 'person'},  ->
        @route('details', { path: ':slug' })
        return
      )
      return
    app.HomeRoute = Ember.Route.extend 
      model: ->

    app.PersonRoute = Ember.Route.extend 
      model: () ->
        return @store.find("Person")

models/person.coffee：

class app.Person extends DS.model
  first: DS.attr("string") 

app.Person.FIXTURES = { person: [
       {
        id: 1, 
        first: "first_1"
       },
       {
        id: 2, 
        first: "first_2"
       }
  ]}

但是当我转到http://localhost:9000/#/person, 时，我得到了这个：

有人知道吗？

编辑： 似乎如果我将 person.coffee 文件从 /models 移动到与 main 和 App 相同的级别，并相应地更改路由器中的“定义”行，它会按预期工作。对我来说仍然是个谜:(

Answer 1

我不能 100% 确定，但问题可能在于 App.Person 的格式错误。

你能像这样重写固定装置吗？

app.Person.FIXTURES = [
   {
    id: 1, 
    first: "first_1"
   },
   {
    id: 2, 
    first: "first_2"
   }
]

Answer 2

您应该使用reopenClass 来定义您的固定装置，因此请遵循以下原则：

App.Documenter.reopenClass({
  FIXTURES: [
    { id: 1, firstName: 'Trek', lastName: 'Glowacki' },
    { id: 2, firstName: 'Tom' , lastName: 'Dale'     }
  ]
});

如示例中所示http://emberjs.com/guides/models/the-fixture-adapter/

您使用的方法已过时。
