Remove sub-document from Mongo with mongoose

Question

I am trying to remove an item from a collection that is stored in a mongoose document. My document looks like this:

{
  \"__v\": 3,
  \"_id\": \"5221040475f         


        

Answer 1

    const deleteitem = (req, res) => {
    var id = req.body.id
    var iditem = req.body.iditem

    Venta.findOne({'_id': id}, function(err,result){
        if (err) {
            console.log(err);            
        }else{
            result.items.pull(iditem)
            result.save()
        }
    })}
module.exports = {deleteitem }
