i am trying to insert new documents in my task collection and the print all the documents inserted by using result.ops method
const mongodb = require('mongodb')
const MongoClient = mongodb.MongoClient
const connectionURL = 'mongodb://127.0.0.1:27017'
const databaseName = 'task-manager'
MongoClient.connect(connectionURL, { useNewUrlParser: true }, (error, client) => {
if (error) {
return console.log('Unable to connect to database!')
}
const db = client.db(databaseName)
db.collection('tasks').insertMany([
{
description: 'Clean the house',
completed: true
},{
description: 'Renew inspection',
completed: false
},{
description: 'Pot plants',
completed: false
}
], (error, result) => {
if (error) {
return console.log('Unable to insert tasks!')
}
console.log(result.ops) //returns undefined
console.log(result) // returns only 2 methods
})
})
// console.log returns only 2 methods insertedcounts & insertedids
https://stackoverflow.com/a/68424173/16483030 Here is your answer. In version 4 insertOne returns insertOneResult that have only 2 properties: acknowledged and insertedId. So you can use insertedId. That makes sense because if it is one, an array is not necessary.
