问题描述

我有一个简单的 Cloud Code 命令来创建或更新对象。如果没有传入 objectId，例程将创建一个新对象并返回 objectId。如果参数列表中存在 objectId，则获取对象并相应地更新参数。

例程适用于新对象。

当我尝试更新一个对象时，object.save() 失败了，尽管 object.fetch() 子程序在工作。

error: code=101, message=Object not found.

详细的服务器日志表明一个非常奇怪的 PUT 命令...

PUT /parse/classes/Receipt/[object%20Object]

我希望看到的是

PUT /parse/classes/Receipt/GJaXcf7fLD

对象 ACL 是公共(public)的 r+w

为什么 object.save() 不能使用有效的 objectId？

云代码

Parse.Cloud.define("uploadReceipt", function(request,response) {
    var Receipt = Parse.Object.extend("Receipt");
    var receipt = new Receipt();

    // passed in parameters are ['property' : ['type' : t, 'value' : v]]
    var dict = request.params;
    var objectIdDict = dict["objectId"];
    console.log("Object Dict: " + objectIdDict);
    Parse.Promise.as().then(function() {
        // if we already have an objectId we are UPDATING
        // Need to FETCH first
        if (objectIdDict != undefined) {
            console.log("Searching for ID: " + objectIdDict["value"]);
            receipt.set("objectId",objectIdDict["value"]);
            return receipt.fetch();
        }
        else {
            console.log("NEW RECEIPT");
            return Parse.Promise.as(receipt);
        }

    }).then(function(receipt) {
        console.log("Receipt: " + receipt.id);
        // copy over the keys from our passed in parameters to the object
        for (var key in dict) {
            //console.log("Key: " + key + "   Value: " + dict[key]["value"]);
            if (dict[key]["type"] == "Raw") {
                console.log("Key: " + key + "   Value: " + dict[key]["value"]);
                receipt.set(key,dict[key]["value"]);
            }
            else if (dict[key]["type"] == "Date" && key != "updatedAt") {
                console.log("Key: " + key + "   Value: " + dict[key]["value"]);
                var time = dict[key]["value"] * 1000;   // milliseconds
                receipt.set(key,new Date(time));
            }
            else {
                // object type
                var Obj = Parse.Object.extend(dict[key]["type"]);
                var newObj = new Obj();
                newObj.id = dict[key]["value"];
                receipt.set(key,newObj);
            }
        }

        // make sure our user is set
        receipt.set("user",request.user);

        // adjust the status because it has now been uploaded
        receipt.set("status",RECEIPT_SUBMITTED);

        console.log("Prior to save");
        return receipt.save();

    }).then(function(receipt) {
        console.log("Finished");
        response.success({"status":receipt.get("status"),"objectId":receipt.id});

    },function (error) {
        console.log(error);
        response.error(error);
    });
});

重现步骤

1. 使用新对象的数据从 iOS SDK 调用云代码
2. 请注意该命令有效并且一个新对象已添加到数据库
3. 使用更新后的信息再次调用命令
4. 请注意该命令因未找到对象而失败

预期结果

对象应该相应地更新

实际结果

error: code=101, message=Object not found.

最佳答案

在解析服务器社区和 GitHub 用户的帮助下解决了这个问题 flovilmart

在“更新”对象的情况下，我为收据添加了一个字典条目。这已成功检索到我要更新的收据。

但是，问题在于，一旦我拉入收据对象并遍历我的属性字典以进行更新...我再次遇到了收据对象信息。因此，我试图将 Receipt 指针的属性添加到我的 Receipt 中，指针本身就是它!呃。

最后一个 else 子句需要一个条件来不包含指向收据(本身)的指针

  for (var key in dict) {
    if 
    ....
    else if (dict[key]["type"] != "Receipt"){
      // object type, but don't include ourself!  (the Receipt)
      var Obj = Parse.Object.extend(dict[key]["type"]);
      var newObj = new Obj();
      newObj.set("objectId",dict[key]["value"]);
      receipt.set(key,newObj);
    }
  }
