Question

我有这个Emberjs应用程序我正在构建所有船形状，但出于某种原因，当我从“患者”视图点击链接时，Ember加载“患者”视图，但不加载模型。但是，如果我在“/：patient_id”路线重新加载页面，则会加载模型。我错过了什么？

DS.RESTAdapter.map 'App.InboxRecording',
  recording: {embedded: 'always'}

App.Store = DS.Store.extend
  adapter: DS.RESTAdapter.create()    

App.Router.map ()->
  this.resource(
    'patients', {path: '/' }, ->
    this.resource(
      'patient', {path: '/:patient_id' }
    )
  )
App.PatientsRoute = Ember.Route.extend({
  model: () ->
    App.Patient.find()
});

App.PatientRoute = Ember.Route.extend({
  model: (params) ->
    App.Patient.find(params.patient_id)
});

App.Patient = DS.Model.extend({
  first_name: DS.attr('string'),
  last_name: DS.attr('string'),
  last_ecg_taken: DS.attr('date'),
  date_of_birth: DS.attr('date'),
  email: DS.attr('string'),
  gender: DS.attr('string'),
  height: DS.attr('string'),
  weight: DS.attr('string'),
  medications: DS.attr('string'),
  smoker: DS.attr('string'),
  inbox_recordings: DS.hasMany('App.InboxRecording')
  //medical_conditions: DS.attr('string'),
});

App.InboxRecording = DS.Model.extend({
  flagged: DS.attr('boolean'),
  read: DS.attr('boolean'),
  overread: DS.attr('boolean'),
  patient: DS.belongsTo('App.Patient'),
  recording: DS.belongsTo('App.Recording')
  //filter: DS.hasMany('App.Filter')
});

App.Recording = DS.Model.extend({
  activities: DS.attr('string'),
  avg_heart_rate: DS.attr('string'),
  recorded_at: DS.attr('date'),
  symptoms: DS.attr('string'),
  inbox_recording: DS.belongsTo('App.InboxRecording')
});

Answer 1

我认为这应该有效。我只有一点怀疑。 Plz试试这个：

{{#each patient in controller.model}}
  <td>{{#linkTo 'patient' patient}}{{patient.first_name}}{{/linkTo}}</td>
   ...
{{/each}}

我认为您的方法可能无法将正确的对象传递给linkTo帮助程序。

Answer 2

好的，所以问题很糟糕，我需要关闭它，因为问题在于模型和从服务器返回的响应。我的坏：\

Emberjs linkTo helper没有加载模型
