How to remove multiple records in nodejs using mongoose - node.js

Question

Tried to remove multiple records in single call from mongodb using mongoose but not working.Where i want to change in my code.Please help to find solution.
In my code if i use like this.. it is working..
({ p_id: { $in: ['Cs1', 'Cs2', 'Cs3']} }
but if use below like
({ p_id: { $in: [records_pids] } } it is not working.Because i am getting this array values by api call.
MongoDB:
{
p_id:"Cs1",
name:"Test",
value:"Power"
},
{
p_id:"Cs2",
name:"Test",
value:"Power"
},
{
p_id:"Cs3",
name:"Test",
value:"Power"
},
{
p_id:"Cs4",
name:"Test",
value:"Power"
},
{
p_id:"Cs5",
name:"Test",
value:"Power"
}
data.controller.js:
module.exports.deleteMultipleRecord = (req, res, next) => {
var collectionMDName = req.query.collectionname;
var records_pids = req.query.pids; //Array value Cs1, Cs2, Cs3
var tableMDModal = mongoose.model(collectionMDName);
tableMDModal.deleteMany({ p_id: { $in: [records_pids] } }, function(err, docs) {
if (err) {
console.log('ss' + err);
return
} else {
console.log("Successful deleted selected records");
res.json({ data: docs, success: true, msg: 'Successful deleted selected records.', cname: collectionMDName });
}
})
}

Answer 1

module.exports.deleteMultipleRecord = (req, res, next) => {
var collectionMDName = req.query.collectionname;
var records_pids = req.query.pids; //Array value CS1, CS2, CS3
var tableMDModal = mongoose.model(collectionMDName);
tableMDModal.deleteMany({ p_id: { $in: records_pids } }, function(err, docs) {
if (err) {
console.log('ss' + err);
return
} else {
console.log("Successful deleted selected records");
res.json({ data: docs, success: true, msg: 'Successful deleted selected records.', cname: collectionMDName });
}
})
}
the error is semantic , rather than searching for values $in: [CS1, CS2, CS3], the search is being made as [[CS1, CS2, CS3]]
Also,have a look at https://mongoosejs.com/docs/models.html for defining models.
