解析对象没有成功编辑

Question

我正在写一个函数，查询与各个用户关联的matchCenterItem对象的解析，然后编辑该对象的某些属性。当查询时，响应（results）返回以这种形式：

<matchCenterItem: 0x7f84e2c1a4b0, objectId: Je1VxP7dPw, localId: (null)> { 
    categoryId = 9355; 
    itemCondition = Used; 
    itemLocation = US; 
    maxPrice = 350; 
    minPrice = 250; 
    parent = "<PFUser: 0x7f84e2c20c10, objectId: kfEHfG4FUD>"; 
    searchTerm = "iphone 5 unlocked"; 
} 

然后我想更新发送与PARAMS领域。当功能运行时，它打印出'MatchCenterItem successfully edited!'，但当我检查仪表板时，该项目根本没有更新。我错过了什么吗？完整的代码如下。

Parse.Cloud.define("editMatchCenter", function(request, response) { 

    var matchCenterItem = Parse.Object.extend("matchCenterItem"); 
    var query = new Parse.Query(matchCenterItem); 

    query.contains('searchTerm', request.params.searchTerm); 
    query.equalTo('parent', Parse.User.current()) 

    query.first().then(function(results) { 

    results.set('minPrice', request.params.minPrice); 
    results.set('maxPrice', request.params.maxPrice); 
    results.set('itemCondition', request.params.itemCondition); 
    results.set('itemLocation', request.params.itemLocation); 
    results.save(); 

    }); 

    response.success('MatchCenterItem successfully edited!'); 

});

改变了代码到这一点，它现在的作品：

Parse.Cloud.define("editMatchCenter", function(request, response) { 

    var matchCenterItem = Parse.Object.extend("matchCenterItem"); 
    var query = new Parse.Query(matchCenterItem); 

    query.contains('searchTerm', request.params.searchTerm); 
    query.equalTo('parent', Parse.User.current()) 

    query.first({ 
    success: function(results) { 

     results.set('minPrice', request.params.minPrice); 
     results.set('maxPrice', request.params.maxPrice); 
     results.set('itemCondition', request.params.itemCondition); 
     results.set('itemLocation', request.params.itemLocation); 
     results.save(); 

     response.success('MatchCenterItem successfully edited!'); 

    }, 
    error: function() { 
     response.error('MatchCenterItem NAAAAT successfully edited!'); 
    } 
    }); 

});
