Question

简短说明：ember数据已退出发送student_id作为student_id，而是将其作为学生发送：

{"iep"=>{"effective_on"=>"Wed, 20 Nov 2013 06:00:00 GMT", "includes_transportation"=>false, "transportation_trips"=>nil, "transportation_purpose"=>nil, "student"=>"1234"}}

详细信息版本：

我正在努力在6月份为现有的大型rails应用程序添加一个ember应用程序，但不得不放下它。我再次拾起它，但是从Ember V1.0.0-rc.5-80-gf54e8ef到V 1.1.3 + pre.e0ffbf84和Ember-data从V0.13-30到V1.1.0-beta的颠簸.3-4不止一些事情已经变得混乱。

目前的问题是保存belongsTo关联。

App..Router.map (match)->
  @resource 'students', ->
    @resource 'student', path: ':student_id', ->
      @resource 'studentIeps', path: 'ieps', ->
        @route 'new', path: 'new'
        @resource 'studentIep', path: ':iep_id', ->
          @resource 'studentIepGoals', path: 'goals', ->
            @route 'new', path: 'new'

App.StudentIepsRoute = Ember.Route.extend
  model: ->
    @modelFor('student').get('ieps')

App.StudentIepRoute = Ember.Route.extend
  model: (params)->
    @store.find 'iep', params['iep_id']

App.StudentIepsNewRoute = Ember.Route.extend
  setupController: (controller) ->
    controller.set 'content', @store.createRecord('iep')

App.Iep = DS.Model.extend
  effectiveOn: DS.attr('date')
  includesTransportation: DS.attr('boolean')
  transportationTrips: DS.attr('number')
  transportationPurpose: DS.attr('string')

  student: DS.belongsTo('student')

App.Student = DS.Model.extend
  firstName: DS.attr('string')
  lastName: DS.attr('string')
  fullName: Ember.computed ->
    @get("lastName") + ", " + @get("firstName")
  .property("lastName", "firstName")

  ieps: DS.hasMany('iep')

App.StudentIepsNewController = Ember.ObjectController.extend
  needs: ['student']
  createIep: ->
    iep = @store.createRecord('iep')
    iep.set('effectiveOn', new Date(@get('effectiveOn')))
    iep.set('student', @get('controllers.student.model'))

    @set('effectiveOn', '')

    iep.save().then (model) ->
      App.Router.router.transitionTo('studentIep', model)

当应用程序尝试保存Iep时，它会使用POST

命中服务器

{"iep"=>{"effective_on"=>"Wed, 20 Nov 2013 06:00:00 GMT", "includes_transportation"=>false, "transportation_trips"=>nil, "transportation_purpose"=>nil, "student"=>"1234"}}

哪个当然是炸弹

IepsController中的ActiveRecord :: AssociationTypeMismatch #create

学生（＃70256213944300）预期，得到字符串（＃70256139944060）

因为ember数据已退出发送student_id作为student_id，而是将其作为学生发送。

我在这里缺少什么？

如何让ember保存belongsTo关联？
