Parse platform 错误：找不到要更新的101对象

我有以下parse.com云代码

Parse.Cloud.afterSave("Action", function (request) {

var BookStatus = Parse.Object.extend("BookStatus");
var Book = Parse.Object.extend("Book");
var book = new Book();

var actionType = request.object.get("actionTypePointer").id;
var bookId = request.object.get("bookPointer").id;

var queryBook = new Parse.Query("Book");
var newBookStatus;

queryBook.get(bookId,{
    success: function (gottenBook) {

        newBookStatus = "idOfTheBookStatus"; 

        book.id = bookId;
        book.set("bookStatus", new BookStatus({id: newBookStatus}));
        gottenBook.set("bookStatus", new BookStatus({id: newBookStatus}));

        //OPTION 1
        gottenBook.save(null,{
            success: function(data) {
                console.log("Bookstatus updated1");
            },
            error: function (data,error) {
                // error is a Parse.Error with an error code and description.
                console.log("Error: " + error.code + " " + error.message);
            }
        });
        //OPTION 2
        book.save(null,{
            success: function(data) {
                console.log("Bookstatus updated2");
            },
            error: function (data,error) {
                // error is a Parse.Error with an error code and description.
                console.log("Error: " + error.code + " " + error.message);
            }
        });

    },
    error: function (object, error) {
        // The object was not retrieved successfully.
        // error is a Parse.Error with an error code and description.
        console.log("Error: " + error.code + " " + error.message);
    }

});

选择1 在将bookStatus设置为返回的图书后，我尝试保存查询的图书

选择2 设置book.Id后，我尝试保存新书对象

        book.id = bookId;
        book.set("bookStatus", new BookStatus({id: newBookStatus}));

但是，使用parse.com日志中的两个选项中的任意一个：

错误：找不到要更新的101对象 错误：找不到要更新的101对象

知道我做错了什么吗

提前谢谢

使用fetch的新实现：

Parse.Cloud.afterSave("Action", function (request) {

var BookStatus = Parse.Object.extend("BookStatus");
var Book = Parse.Object.extend("Book");
var book = new Book();

var actionType = request.object.get("actionTypePointer").id;
var bookId = request.object.get("bookPointer").id;

book.id = bookId;
console.log("before fetch book.id" + book.id);
var newBookStatus;

book.fetch({
    success: function (book) {
        newBookStatus = "XMFkXS9NVv";            

        book.set("bookStatus", new BookStatus({id: newBookStatus}));

        console.log("book" + book);
        console.log("book.id" + book.id);
        console.log("book.isValid()" + book.isValid());

        book.save(null,{
            success: function(data) {
                console.log("Book Status updated to:" +newBookStatus);
            },
            error: function (data,error) {
                // error is a Parse.Error with an error code and description.
                console.log("Error: " + error.code + " " + error.message);
            }
        });
    },
    error: function (object, error) {
        // The object was not retrieved successfully.
        // error is a Parse.Error with an error code and description.
        console.log("Error: " + error.code + " " + error.message);
    }

});

}))

结果：

  Input: {"place":{"__type":"GeoPoint","latitude":41.354643806134625,"longitude":2.121594674804572},"bookLocationDescription":"sad","bookPointer":{"__type":"Pointer","className":"Book","objectId":"kWcALge4az"},"actionTypePointer":{"__type":"Pointer","className":"ActionType","objectId":"kJC954w9iO"},"userPointer":{"__type":"Pointer","className":"_User","objectId":"6xpiAHX9Ju"},"createdAt":"2013-05-16T13:59:33.810Z","updatedAt":"2013-05-16T13:59:33.810Z","objectId":"PwlXhKL51l","ACL":{"6xpiAHX9Ju":{"read":true,"write":true},"*":{"read":true}}}
  Result: Success

您的afterSave钩子正在覆盖已获取书籍的对象id。即使您在其上设置了相同的对象id，该对象现在仍认为它脏了，不再是有效的引用

通过使用由

get（）

返回的书籍而不更新其id来避免此问题：

    Parse.Cloud.afterSave("Action", function (request) {

        var BookStatus = Parse.Object.extend("BookStatus");
        var Book = Parse.Object.extend("Book");
        var book = new Book();

        var actionType = request.object.get("actionTypePointer").id;
        var bookId = request.object.get("bookPointer").id;

        var queryBook = new Parse.Query("Book");

        var newBookStatus;

        queryBook.get(bookId,{
            success: function (book) {
                newBookStatus = "idOfTheBookStatus"; 

                book.set("bookStatus", new BookStatus({id: newBookStatus}));

                book.save(null,{
                    success: function(data) {
                        console.log("Bookstatus updated1");
                    },
                    error: function (data,error) {
                        // error is a Parse.Error with an error code and description.
                        console.log("Error: " + error.code + " " + error.message);
                    }
                });
            },
            error: function (object, error) {
                // The object was not retrieved successfully.
                // error is a Parse.Error with an error code and description.
                console.log("Error: " + error.code + " " + error.message);
            }

        });
    });

因为您已经知道这本书的id，所以不必使用查询，您可以创建一个指针并直接获取它

最终余波钩：

    Parse.Cloud.afterSave("Action", function (request) {

        var BookStatus = Parse.Object.extend("BookStatus");
        var Book = Parse.Object.extend("Book");
        var book = new Book();

        var actionType = request.object.get("actionTypePointer").id;
        var bookId = request.object.get("bookPointer").id;

        book.id = bookId;

        var newBookStatus;

        book.fetch({
            success: function (book) {
                newBookStatus = "idOfTheBookStatus"; 

                book.set("bookStatus", new BookStatus({id: newBookStatus}));

                book.save(null,{
                    success: function(data) {
                        console.log("Bookstatus updated1");
                    },
                    error: function (data,error) {
                        // error is a Parse.Error with an error code and description.
                        console.log("Error: " + error.code + " " + error.message);
                    }
                });
            },
            error: function (object, error) {
                // The object was not retrieved successfully.
                // error is a Parse.Error with an error code and description.
                console.log("Error: " + error.code + " " + error.message);
            }

        });
    });

下面是我跑了几圈后是怎么做到的

ParseCrashReporting.enable(this);

// Enable Local Datastore.
Parse.enableLocalDatastore(this);

// Add your initialization code here
Parse.initialize(this, "*******", "******");

ParseUser.enableAutomaticUser();
ParseACL defaultACL = new ParseACL();

ParseACL.setDefaultACL(defaultACL, true);

// save the installation
ParseInstallation.getCurrentInstallation().saveInBackground();

在查找此错误时，我发现此线程最有用。我想补充一点，get的

未找到对象

实际上也意味着

未找到外键引用

get的

未找到

错误可能毫无帮助；对我来说，它甚至没有给出错误发生的行号，错误信息非常模糊，我在任何文档中都找不到该短语的参考

如果您遇到此错误，您会发现很多权限问题的引用，但是如果您已经在使用

主密钥

，那么您需要在所选对象上查找外键引用的对象。

在我看来，第一个after after hook类似于我使用的选项1。选项2被我再次设置的id弄脏了，我现在得到了这个！我用你第二个答案的密码更新了问题。感谢您的帮助@Hector Ramos此book对象是否具有不授予您写访问权限的ACL？日志语句似乎表明您没有保存该对象的权限，只能读取它。var newAcl=newparse.ACL（Parse.User.current（））；newAcl.setPublicReadAccess（true）；book.setACL（newAcl）；witch最后出现在云代码中，比如：“ACL”：{“6xpiAHX9Ju”：{“read”：true，“write”：true}，“*”：{“read”：true}}}我也试图不设置ACL，但我有同样的运气。您是否以对象id为6xpiAHX9Ju的用户身份登录？这是唯一允许保存book对象的用户。
