TypeError:db.findWConditionandler不是MongoDB函数 [英] TypeError: db.findWConditionandler is not a function MongoDB

问题描述

这实际上是我上一个问题的延续，我感到很疑惑，因为我意识到自己并没有问这个问题，而现在我有一个不同的错误响应.

This is actually a continuation of my previous question and I'm reasking as I've realised I didn't quite ask the question problem and now I have a different error response.

这是在db.js中，这是我拥有处理程序时的单独文件. 上下文:我这样返回func，以便在我的index.js中，我可以继续执行mongodb sort操作来查找时间戳最小的用户！

This is in db.js, a separate file while I have the handlers. Context: I return func like this so that in my index.js, I can continue to perform mongodb sort operation to find users with the smallest timestamp!

在服务器控制台中，我收到此响应.TypeError: db.findWConditionandler is not a function我不确定我在做什么错.请咨询！提前致谢！

In my server console, I get this response.TypeError: db.findWConditionandler is not a function I'm not sure what I'm doing wrong here. Pls advice! Thanks in advance!

推荐答案

问题是因为.sort需要光标，而.findOne()没有给出光标.相反，应该使用.find()

The problem is because .sort expects a cursor and .findOne() doesn't not give a cursor. Instead, one should use .find()
