REST在Parse $ in到指针错误代码106的ObjectID中 [英] REST in Parse $in to ObjectID of Pointer Error Code 106

问题描述

我正在尝试获取以下查询：

I'm trying to get the following query:

https://api.parse.com/1/classes/Video?where=
{"course":{"__type":"Pointer","className":"Course","objectId":{"$in":["id1","id2"]}}}

我正在视频表上查询课程字段（这是一个指针）获取所有视频，其中的课程是数组中传递的ID之一（因此我使用$ in）因为如果我不使用$ in，我没有问题，但我不需要它。

I'm querying on Video table, on "course" field (It's a pointer) to get all videos that its course is one of ids passed in the array (For this reason I use $in) because if I don't use $in, I don't have problems but I don't need it.

错误是这样的：

{ 
   code: 106,
   error: "key objectId should be a string"
}

什么我要做？你有什么主意吗？？

What I have to do? Do you have any idea??

谢谢

推荐答案

你可以试试$ inQuery

where={"course":{"$inQuery":{"where":{"objectId":{"$in":["id1","id2"]}},"className":"Course"}}}
