Mongoose delete array element in document and save

by

You can also do the update directly in MongoDB without having to load the document and modify it using code. Use the $pull or $pullAll operators to remove the item from the array :

Favorite.updateOne({ cn: req.params.name }, {
    $pullAll: {
        favorites: req.params.deleteUid,
    },
});

To remove objects from array then

Favorite.updateOne({ cn: req.params.name }, {
    $pullAll: {
        favorites: [{_id: req.params.deleteUid}],
    },
});

(you can also use updateMany for multiple documents)
