ember.js在为其属性设置新值后应用对象 [英] ember.js apply object after setting new value for it's attribute

问题描述

干杯！
简单的动作在这里我有：

Cheers! Simple action here I have:

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
  }));

设置方法运行良好，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：

Set method works well, but when I trying to apply object with new setted property, Ember gives me an error:

Uncaught TypeError: Cannot redefine property: __ember1360328485839 

如何解决这个问题？

推荐答案

尝试创建一个事务，座位到交易，修改座位，然后提交交易。

Try creating a transaction, add the seat to the transaction, modify the seat, then commit the transaction.

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