Question

我有以后的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);
    }

});

OPTION1 在将bookStatus设置为返回的书之后，我尝试保存查询的书。

OPTION2 设置好书后，我尝试保存新书对象.Id

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

然而，在我最终获得parse.com日志的两个选项中的任何一个：

错误：找不到101对象进行更新错误：找不到更新的101对象

知道我做错了什么？

提前致谢！

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

Answer 1

你的afterSave挂钩会覆盖读取的Book的对象id。即使您在其上设置相同的对象ID，对象现在也认为它很脏并且它不再是有效的引用。

通过使用get()返回的书而不更新它的id：

来避免这种情况

    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);
            }

        });
    });

由于您已经知道了本书的ID，因此您可以创建指针并直接获取它，而不是使用查询。

最后的AfterSave钩子：

    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);
            }

        });
    });

Answer 2

这是我在一些人跑来跑去之后的表现

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();

Answer 3

在寻找此错误的同时，我发现此主题最有用。我想补充一点，object not found for get也基本上意味着foreign key reference not found。

not found for get错误可能非常无益;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，我无法在任何文档中找到对该短语的引用。

如果您收到此错误，您会发现许多对权限问题的引用，但如果您已经在使用master key，那么您需要找到您的外键引用的对象选定的对象。
