I am trying to connect to my mongod instance using the following command:
mongo --tls --tlsCAFile mongodb.pem --host localhost

But the .pem file has a passphrase which I don't know how to pass. Hence I am getting the error,

Failed global initialization: InvalidSSLConfiguration Unable to load PEM from 'mongodb.pem': Failing importing certificate(s): Passphrase is required for import/export.

Need some help! Thanks in advance.

Hi! , please I need some design wisdom, I'm creating an application that uses two mongo databases, One database contains a User Collection(USERDB), the other contains a Post Collection(POSTDB), Would it make some sense to use a user's document objectID in the USERDB as an author id in the POSTDB ?

function(x){
db.zhulirecords.updateOne({_id: x._id}, {$set:{initiatorUserId: String(x.initiatorUserId)}})
}

Is there a way to read an object back in dot notation? I'm looking for a quick and dirty way to read a collection and dump it to CSV.

Hello. I am trying to create a new user to access a new DB. I connect using a root user to the admin db and then I try to create a new user on a new db...

MongoClient.connect( process.env.JEST_MONGODB_URL, function( err, client ) {
    if ( err ) return console.error( err );
    const admin = new Admin( client.db( process.env.MONGODB_DATABASE ) );
    admin.addUser(
        process.env.MONGODB_USERNAME,
        process.env.MONGODB_PASSWORD, {
            roles: [
                {
                    role: 'readWrite',
                    db: process.env.MONGODB_DATABASE
                }
            ]
        },
        function( err, result ) {
            if ( err ) return console.error( err );
            console.log( result );
            client.close();
        });
});

Im using here client.db() and passing that to new Admin() because I thought that would create the user in that db, but its creating it in the admin db instead.

When I use the mongo shell I can use newdb and then create the new user and that works fine. How can I do this with mongodb native driver for node?

Hi. How do I catch the database failing from a collection stream cursor?

Looks like I can shut down my database, and the stream cursor doesn't complain at all

Hey, is there any guidance on how to configure mongodb with replicasets on travisci? I'm trying to create tests using transactions.

The only reference I have found so far, but I'm not too big of a fan of sleep methods: https://georgeshank.com/how-to-enable-a-mongodb-replica-set-on-travis/

{
    'key': 'ONE',
    'stages': [
        { name: 'prod', values: [ { 'value': 'one' } ] },
        { name: 'qa',   values: [ { 'value': 'two' } ] }
    ]
}

I need to do an update in that document, I'd like to either add a new stage if it doesnt exist or add to stage values if it already exists. Is this possible in a single mongo request? Or do you think i should rework my design?

Hi people!

Hello, please a simple question: Should indexes be registered once only in a database's lifetime? What I'm currently doing is running the code to register the index at every initialization of the service which needs this. but is this the best approach or not ?

Manav Misra

@manavm1990_gitlab

Noob, so NS. WIKI that you will get ✉️s from the service advising about things that should be indexed based on what actually happening.

Guys I searched all the stack I tried every examples but I couldnt update object inside of array

Here is the db

    mail: string
    password: string,
    db: {
        dialogEngine: {
            assistants: [
                [
                    apiKey: string,
                    maintenance: boolean
                ]
            ]
        }
    }

I want to update maintenance boolean here is the code I tried

    var update = await global.dialogEngine.db.db('users').collection('userdatabase').updateOne({
        mail: req.body.mail,
        password: req.body.password
    },
    {
        $set: {
            'db.dialogEngine.assistants.$[elem].maintenance':  req.body.maintenance
        }
    },
    {
        arrayFilters: [
            {
                'elem.apiKey': req.body.apiKey
            }
        ]
    });
