在猫鼬中，如何按日期排序? (node.js) [英] In Mongoose, how do I sort by date? (node.js)

问题描述

假设我在猫鼬中运行此查询:

let's say I run this query in Mongoose:

Room.find({}, function(err,docs){

}).sort({date:-1}); 

这不起作用！

推荐答案

排序已经发展发行版中的某些答案不再有效.从Mongoose的 4.1.x 版本开始，可以通过以下任意一种方式对date字段进行降序排序:

Sorting in Mongoose has evolved over the releases such that some of these answers are no longer valid. As of the 4.1.x release of Mongoose, a descending sort on the date field can be done in any of the following ways:

Room.find({}).sort('-date').exec(function(err, docs) { ... });
Room.find({}).sort({date: -1}).exec(function(err, docs) { ... });
Room.find({}).sort({date: 'desc'}).exec(function(err, docs) { ... });
Room.find({}).sort({date: 'descending'}).exec(function(err, docs) { ... });
Room.find({}).sort([['date', -1]]).exec(function(err, docs) { ... });
Room.find({}, null, {sort: '-date'}, function(err, docs) { ... });
Room.find({}, null, {sort: {date: -1}}, function(err, docs) { ... });

对于升序排序，请在字符串版本中省略-前缀或使用1，asc或ascending的值.

For an ascending sort, omit the - prefix on the string version or use values of 1, asc, or ascending.
