Question

我的_User表中有两个数组：hasCreated和isMemberOf，它们包含属于Group表的组对象，我有以下Cloud Code：

Parse.Cloud.beforeSave('Group', function(request, response) {

    var creator = request.user;
    if (!_.isObject(creator)) {
        response.error('creator is not specified');
    }
    else {
        var group = request.object;
        var isCreate = group.isNew();

        //        Group is being created
        if (isCreate) {
            if (!_.isString(group.get('title'))) {
                response.error('group title is required');
            }
            else {
                group.set('createdById', creator.id);
                response.success();
            }
        }
        //        Group is being updated
        else {
            response.success();
        }
    }
});

Parse.Cloud.afterSave('Group', function(request) {

    var creator = request.user;
    var group = request.object;
    var wasGroupCreated = !group.existed();

    if (wasGroupCreated) {

        creator.addUnique('hasCreated', group);
        creator.addUnique('isMemberOf', group);

        creator.save();
    }
});

Parse.Cloud.afterDelete('Group', function(request) {

    var creator = request.user;
    var group = request.object;

    creator.remove('hasCreated', group);
    creator.remove('isMemberOf', group);

    creator.save();
});

当我发布到组时，它会按预期发生，但是当我用

获取用户时

includeKey=isMemberOf&hasCreated

我得到以下内容：

hasCreated: [
    {
        __type: Object,
        className: Group,
        createdAt: 2014 - 06 - 04T18: 59: 02.325Z,
        createdById: abc,
        …
    }
    {
        __type: Pointer,
        className: Group,
        objectId: def
    }
    {
        __type: Pointer,
        className: Group,
        objectId: ghi
    }]
isMemberOf: [
    {
        __type: Object,
        className: Group,
        createdAt: 2014 - 06 - 04T18: 59: 02.325Z,
        createdById: abc,
        …
    }
    {
        __type: Pointer,
        className: Group,
        objectId: def
    }
    {
        __type: Pointer,
        className: Group,
        objectId: ghi
    }]

所以基本上，我只是完全取回了三个组中的一个，而且_type字段也是不同的。以下是我在User表中hasCreated和isMemberOf数组字段中的内容：

[{
    "__type": "Pointer",
    "className": "Group",
    "objectId": "abc"
}, {
    "__type": "Pointer",
    "className": "Group",
    "objectId": "def"
}, {
    "__type": "Pointer",
    "className": "Group",
    "objectId": "ghi"
}]

我做错了什么？我需要为每个组获取完整的对象。请指教！谢谢！

对于Parse来说，这个看起来像是一个暂时的问题（对我来说只持续了几天）。 include（not includeKey）已经可靠地给了我很长时间的完整对象了。
