Question

在我的组件中，我在控制台上收到以下弃用警告：

DEPRECATION: Action handlers implemented directly on views are deprecated in favor of action handlers on an `actions` object ( action: `setVehicleModels` on <App.VehicleDetailsComponent>)

我相信这是因为我在最后一种方法中调用了@send 'setVehicleModels'，但我无法弄清楚需要改变什么。 setVehicleComponent可以成为一个行动并拥有.on("init")吗？

App.VehicleDetailsComponent = Ember.Component.extend(
  setVehicleModels: (->
    model = @.get('model')
    store = App.__container__.lookup('store:main')
    store.find('automobile').then ((autos) =>
      @.set('autoModels', autos.filterBy('autoId', model.get('autoId')))
    )
    @.set('selectedModel', model)
  ).on('init')

  modelChanged: (->
    auto = @.get('selectedModel')
    @.set('model', auto)
    @.rerender()
  ).observes('selectedModel')

  updateAutoModels: (->
    @send 'setVehicleModels'
  ).observes("model")
)

完整筹码：

当您使用@.send时，它希望该函数位于actions哈希中，如果它不在哈希值中，您将获得该弃用警告。

如果您想直接从组件中调用本地函数，可以直接调用它，如@.setVehicleModels()

尝试解决Component中的弃用错误
