Mongoose deleting (pull) a document within an array, does not work with ObjectID

Question

I have the following mongoose schema:

user = {
    \"userId\" : \"myId\",
    \"connections\":
    [{
        \"dateConnectedUnix\": 1334567891,
        \"is         


        

Answer 1

You can do it in mongoose 5.4.x and above

const result = await User.findByIdAndUpdate(user_id,
            {
                $pull: {
                    someArrayName: { _id: con_id }
                }
            }, { new: true });


if (result)
    console.log(result)

The item from connections array will be removed based on provided property _id value
