Hi, I am trying to return my query in backwards order from which it was created.
The docs are a little unclear on how to use the sort method:
Here is my schema:
const mongoose = require('mongoose'),
Schema = mongoose.Schema,
ObjectId = Schema.Types.ObjectId;
let PostSchema = new Schema({
title : String,
description: String,
image : String,
tags : [String],
original_poster: {
type: Schema.Types.ObjectId,
ref: 'User',
required: true
},
date: {
type: Date,
default: new Date()
}
})
module.exports = mongoose.model('Post',PostSchema);
I have run,
db.posts.find().sort({date:-1}).pretty()
For example, if my model was a 'Post' model and my first post was 'hello world' and my second post was 'this is a post'. I would like to see:
['this is a post', 'hello world']
However, what I am actually seeing is ['hello world','this is a post']

Figured out the answer
in posts schema add:
date: {
type: Date,
default: Date.now
}
then db.posts.find().sort({date:-1}).pretty() will yield the posts sorted from most recent to least recent
You have to add a creation timestamp in your schema and sort by its key.
let PostSchema = new Schema({
title : String,
description: String,
date : Date, // Here is your date
image : String,
tags : [String],
original_poster: {
type: Schema.Types.ObjectId,
ref: 'User',
required: true
}
})
and when you insert a document, use:
date: new Date()
