javascript - Ember.js/Emblem.js 未捕获错误 : Nothing handled the event 'createUser'

Question

我想我可能误解了 Ember 连接路由、 View 和模板的方式，但我无法弄清楚以下结果会导致错误:

Uncaught Error: Nothing handled the event 'createUser'.

我的文件如下:

javascripts/router.js.coffee

App.Router.map ->
  @resource 'account', ->
    @route 'index', path: '/'

javascripts/routes/account_router.js.coffee

App.AccountRoutes = Ember.Route.extend
  model: -> App.User.find()

javascripts/controllers/account_controller.js.coffee

App.AccountController = Ember.ObjectController.extend
  createUser: ->
    App.User.createRecord
      field1: @get('field1')
      / etc

javascripts/views/account_view.js.coffee

App.AccountView = Ember.View.extend
  templateName: 'account'

javascripts/templates/account/index.emblem

form.form submit="createUser"
  / fields

我认为您缺少 actions 哈希值。

模板内的操作，例如:

<script type="text/x-handlebars" id="foo">
  <div {{action "doFoo"}}>Click here</div>
</script>

需要出现在相应的 Controller 或路由中的操作对象内:

App.FooController = Ember.ObjectController.extend({
  actions: {
    doFoo: function() {
      alert('Foo');
    }
    // ... more actions here
  }
});

就您的情况而言，我认为您需要更新为以下内容:

App.AccountController = Ember.ObjectController.extend
  actions:
    createUser: ->
      App.User.createRecord
        field1: @get('field1')
