Ember.js從控制器獲取數據

Question

我有一個控制器，在其中定義TakenSeatNumbers變量：

TravelClient.TourSeatsController = Ember.ObjectController.extend({
  selectSeat: function(seat) {
    var orderTransaction = TravelClient.store.transaction();
    var takenSeatNumber = orderTransaction.createRecord(TravelClient.TakenSeatNumber, {number: seat.get('id')});
  }
});

如何從tour/seats模板訪問TakenSeatsNumbers ？ Tour模型在TourSeatsController的上下文中。

根據我的評論，將該函數變量（ takenSeatsNumber ） takenSeatsNumber為控制器內的一個屬性，使其為公共屬性，類似於以下內容：

TravelClient.TourSeatsController = Ember.ObjectController.extend({
  takenSeatNumber: null, 
  selectSeat: function(seat) {
    var orderTransaction = TravelClient.store.transaction();
    this.set('takenSeatNumber', 
             orderTransaction.createRecord(TravelClient.TakenSeatNumber, {number: seat.get('id')})
    );
  }
});
