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

mongoose: 4.11.11
What have worked for me is the following syntax:

const removeTansactionFromUser = (userId, connectionId) => {
    return User.findByIdAndUpdate(userId, { $pull: { "connections": connectionId} }, {'new': true} );
};

Mongoose support id in string format or ObjectId format.
Tip: new ObjectId(stringId) to switch from string to ObjectId
