I am using Node.js and mongoose Module, I am looking for a way to count how many documents a user has and then if they have more then 0 documents it would edit their existing document and add the input so at the end it would have the previous text + the text that the user sent, so far this is how much I gotten.
const List = require('../Models/list.js')
List.countDocuments({}, function(err, count) {
if(count>0){
//edit document
}
else if(count=0){
const input = List.create({
User: User.name,
Songlist: args[0],
})
}
})
console.log('done')
here is how I think the code would look like
List.update(User.name) => update Songlist into List.Songlist + '|' + args[0]
I have never seen an update method like that. I am a nodejs developer. well, maybe there's a way like that.
Here's how I do to update a document
await Product.findByIdAndUpdate(id, //here where I have written "id" you have to write the id of the document you want to update. { //here in this object you have to put the variables of updated values title: title, description:description, product_id:product_id, category, price, });
there is also another method
await Product.findOneAndUpdate(name: 'asim', //let's suppose
{ //updated values
title:title,product: product
})you can also read the documentation here https://mongoosejs.com/docs/tutorials/findoneandupdate.html
