Meteor客户端排序集合 [英] Meteor client side sort Collection

问题描述

我有一个DrawingHistory集合，它存储用于重绘canvas数据的数据，但我似乎找不到一种方法来按时间属性排序信息。这是我当前的函数

I have a DrawingHistory collection which stores data to be used for redrawing canvas data, but I can't seem to find a way to sort the information by a time property. Here's my current function

DrawingHistory.find().observeChanges
  added: ( id , data ) =>
    @setupUserDraw data unless Session.equals 'user_id' , data.sid

我看着网上排序，人们说， DrawingHistory.find（）。sort（{time：-1}）但find（）不有排序属性。

Sometimes the order gets messed up, and I looked online for sorting where people say to do DrawingHistory.find().sort( { time: -1 } ) but find() doesn't have a sort property. Any ideas where I'm off?

推荐答案

如果我的记忆没有让我失望，这应该做，第一个 {} 是选择器，第二个 {...} 是选项。

If my memory isn't failing me, this should do it, the first {} being the selector, the second {...} being the options.

DrawingHistory.find({}, {sort: {time: -1}});

编辑：找到 docs on find（）。
