ember.js – model.save()与model.get(‘store’)的区别.commit()

// 'this' is the controller
this.get('model').save();

和

// 'this' is the controller
this.get('model').get('store').commit();

？在我做的小测试中,他们都给了我相同的结果.@R_317_10675@用哪一个？

我调查了第一个,并呼叫

Ds.Model = Ember.object.extend(
  ...
  save: function() {
    this.get('store').scheduleSave(this);

    var promise = new Ember.RSVp.promise();

    this.one('didCommit',this,function() {
      promise.resolve(this);
    });

    return promise;
  },

那么问题就变成了,这个.get(‘store’).scheduleSave(this)和this.get(‘store’)之间的主要区别是什么？commit()？

Ds.Store = Ember.object.extend(Ds._Mappable,{
  ...
  scheduleSave: function(record) {
    get(this,'currenttransaction').add(record);
    once(this,'flushSavedRecords');
  },...
  /**
    This method delegates commitTing to the store's implicit
    transaction.

    Calling this method is essentially a request to persist
    any changes to records that were not explicitly added to
    a transaction.
  */
  commit: function() {
    get(this,'defaulttransaction').commit();
  },

我不知道哪一个更好.我正在倾向于保存(),因为它似乎在商店周围.

(我在github上找不到这些代码,不知道github或者emberjs的amazonaws版本是否是最新版本,这是github上的类似版本：model’s save(),它调用store’s scheduleSave()和store’s commit())
