Parse platform 解析云“；“保存之前”；不保存数据

我正在使用parsebeforeSave方法保存订单，下面是代码：

    //Before save an order - if finish - set priority to 0
    Parse.Cloud.beforeSave("UserToOrders", function(request, response) {
    Parse.Cloud.useMasterKey();
    var preStatus = request.object.get("OrderStatus");
    if (preStatus == "Finish") {
        request.object.set("Priority",0);
        console.log("beforeSave(\"UserToOrders\")\t Order (" + request.object.id + ") Status is 'Finish' So Priority set to '0'");
    }
    else {
        console.log("beforeSave(\"UserToOrders\")\t Order (" + request.object.id + ") Status Changed to: " + preStatus);
        request.object.set("OrderStatus",preStatus);

    }
    response.success();
});

以下是日志：

但数据库中没有任何更改

我错过了什么

谢谢。

var preStatus中的值与您要保存的值相同

var preStatus = request.object.get("OrderStatus");

并且您正在“保存”相同的值，您可以删除这一行

request.object.set("OrderStatus",preStatus);

如果不是您想要的，请提供“OrderStatus”=Finish的日志，我已经找到了。这是一个ACL权限问题。

一个客户创建的订单，而另一个客户创建的机会

您的代码看起来应该可以工作，我会尝试将else语句与花括号放在同一行，或者尝试放置一些字符串作为响应；谢谢最后我终于明白了，这是一个ACL权限问题。我有两个android项目应用程序使用相同的解析应用程序，一个是客户端，另一个是商店，它们都需要更新数据库中的相同行。
