干杯! 我有简单的行动:

TravelClient.TourSeatsController = Ember.ObjectController.extend({
  selectSeat: function(seat) {
    // console.log(seat.get('id'));
    // console.log(seat.get('free'));
    seat.set('free', false);
    TravelClient.Seat.apply(seat);
    // console.log(seat.get('free'));
  }
});

我的HTML:

      {{#each seat in controller.seatsArray}}
        <li class="item">
          {{#if seat.free}}
            <div class="counter-value">
              <a href="#" {{action "selectSeat" seat}}>{{seat.id}}</a>
            </div>
...............................................................................

对象的结构:

  ...addObject(TravelClient.Seat.create({
    id: i,
    free: true
  }));

Set方法效果很好,但是当我尝试使用新的setted属性应用对象时,Ember给了我一个错误:

Uncaught TypeError: Cannot redefine property: __ember1360328485839 

如何解决这个问题?

尝试创建交易,将席位添加到交易中,修改席位,然后提交交易。

TravelClient.TourSeatsController = Ember.ObjectController.extend({
  selectSeat: function(seat) {
    var transaction = new App.store.transaction();
    transaction.add(seat);
    seat.set('free', false);
    transaction.commit();
  }
});
