exports.Post = mongolass.model('Post', {
author: { type: Mongolass.Types.ObjectId },
title: { type: 'string' },
content: { type: 'string' },
pv: { type: 'number' }
});
exports.Post.index({ author: 1, _id: -1 }).exec();// 按创建时间降序查看用户的文章列表 这里如何理解？
![[Web front-end] Node.js quick start](https://img.php.cn/upload/course/000/000/067/662b5d34ba7c0227.png)
exports.Post.index({ author: 1, _id: -1 }).exec();
The above code is creating a composite index (author ascending order, _id descending order)
For reference.
