问题描述
在猫鼬中,我需要在集合中查找元素并对其进行计数,并同时获得查找和计数的结果.我尝试过
In Mongoose, I need to find elements in a collection and count them, and getting both the results of the find and count. I have tried
Model.find().count(function (err, count) {
// Get count, but cannot get results of find
});
有没有一种方法可以同时获取find()和count()而不调用它们两次?
Is there a way to get both find() and count() without calling them twice?
推荐答案
您可以使用返回数组的长度:
You can use the length of the returned array:
Model.find().exec(function (err, results) {
var count = results.length
});
