用猫鼬和日期查询 [英] Querying with mongoose and dates

问题描述

我正在尝试找出如何对猫鼬进行特定查询. 我在mongodb中有这样的内容:

I'm trying to find out how to do an specific query with mongoose. I have in mongodb something like this:

{ "_id" : 1, "modificationDate" : ISODate("2013-06-26T18:57:30.012Z") }
{ "_id" : 2, "modificationDate" : ISODate("2013-06-26T18:57:35.012Z") }

我想获取所有实际日期和modificationDate之间的差异大于5天的对象.

I want to obtain all the objects where the difference between the actual date and modificationDate is greater than 5 days.

推荐答案

计算5天的截止时间，然后使用$lt运算符和计算出的截止值执行find:

Calculate the 5-days-old cutoff time and then perform a find using the $lt operator and the calculated cutoff:

var cutoff = new Date();
cutoff.setDate(cutoff.getDate()-5);
MyModel.find({modificationDate: {$lt: cutoff}}, function (err, docs) { ... });
