在Parse.com云代码中，如何按其子表对记录进行排序 [英] In Parse.com cloud code, How to sort records by its child table

问题描述

这个问题是关于在Parse.com云代码中按Pointer对象排序.

This question is about sorting by Pointer object in Parse.com cloud code.

我有一个Class A对象，而A.pointer是一个指向Class B的Pointer对象.

I have an Class A object, and A.pointer is a Pointer object which point to Class B.

我想按B.sortfield对数据库中的A进行排序.

And I want to sort A in database by B.sortfield.

我试图像下面那样使用innerQuery，但似乎不起作用.

I've tried to use innerQuery like below, but seems not work.

        var query = new Parse.Query(A);
        var innerQuery = new Parse.Query(B);
        innerQuery.descending('sortfield');
        query.matchesQuery("pointer", innerQuery);
        query.......

有人可以告诉我该怎么做吗? tnx！

Could anybody tell me how to do it? tnx!

推荐答案

在下面的答案中，Parse不支持这种查询.真的让我很失望.

Found below answers, Parse does not support such query. It really disappointed me.

sort-a-query-根据另一个表中的数据 和 rest-api-sorting-query-through-a-pointer
