Question

{

    {
        "fund_values": [
            {
                "percentage": 77,
                "_id": "5e240207c5f5041bd8c90e43"
            },
            {
                "percentage": 81,
                "_id": "5e2404edfe10180a249cdd2b"
            }
        ],
        "_id": "5e23f9d146608630a0bcea7e"
    },

"_id": "5e0894ff361c550b38f4d46f"
}

Hi. i decided to ask again even though this may look like a duplicate post. I have tried the suggested posted but they do not work.

This is what i have currently

Client.findOneAndUpdate({ '_id': req.params.client_id, 'policies._id': req.params.policy_id , 'policies.0.fund_values._id': req.params.client_fund_value_id }, 
    { 
        '$set': { 
            'policies.$.fund_values.0.percentage': req.body.percentage
        } 
    }, { new: true }, 
    function(err, client) {
        if (err) {
            res.status(500).send(err);
            return;
        }

        res.json(client);
    }
);

This may look ok but this code specifically alters the first fund value object in the array. i read that using $ won't work. so in this case what is the correct syntax?

Please share correct data of collection because sometime you use id key name but condition used _id key ? — Mahesh Bhatnagar, Jan 19 '20 at 10:23
Please sir pull that data after push date in fund_values array — Mahesh Bhatnagar, Jan 19 '20 at 10:52
i did a different route. i used just findOne() and then searched the arrays by id via javascript. i was trying to see if it was possible using findOneAndUpdate() but it looks impossible. — chitgoks, Jan 19 '20 at 10:56
