Ember-在没有承诺的循环中执行异步操作

Question

我想知道如果给出的示例可以在真实服务器上满足竞争条件，是否可以在localhost上运行。给定情况 - 用户从表单中删除一些人（比如studyForm和studyPersons）我已经将personToDelete添加到一个数组中稍后 - 编辑操作我在循环中删除它们

 // A punch of persons chosen to be deleted
self.markedForDeleted.forEach(function(trashed){
                trashed.destroyRecord();
 });

 this.get('person').save().then(personEditSuccess, personEditFailure);

我应该像这样编辑吗？

var onDeleteSuccess = function(wasAnyToDelete){
   if (wasAnyToDelete){
    deletedPersons ++;
   }
   if(deletedPersons === lengthOfAllPersons) { 
     this.get('person').save().then(personEditSuccess, personEditFailure);
   }
};

// A punch of persons chosen to be deleted
self.markedForDeleted.forEach(function(trashed){
                trashed.destroyRecord().then(onDeleteSuccess, onDeleteFailure);
 });

正在使用

Ember.RSVP.all(personsToDelete.invoke('destroyRecord')).then(deletePersonSuccess, deletePersonFailure);
