问题

英文:
I have an array in my model document. I would like to remove one id in that array. Is this possible?
This is what I tried.
module.exports.RemoveFavourite = async (req, res, next) => {try {const userId = req.params.user;const favouriteId = req.params.event;const removeFavourite = await User.updateOne({ _id: userId },{ $pull: { favourites: favouriteId } });res.status(200).json(removeFavourite);} catch {res.status('404').json('error');}};

将favouriteId从字符串转换为ObjectId。
const mongoose = require("mongoose");module.exports.RemoveFavourite = async (req, res, next) => {try {const userId = req.params.user;const favouriteId = req.params.event;const removeFavourite = await User.updateOne({ _id: userId },{ $pull: { favourites: mongoose.Types.ObjectId(favouriteId) } });res.status(200).json(removeFavourite);} catch {res.status('404').json('error');}};
英文:
convert favouriteId string to ObjectId

const mongoose = require("mongoose")
