remove query in mongodb by _id with nodejs

Question

remove query in mongodb by _id with nodejs

removing a row in mongodb isn't seem to be that easy as in SQL lol, well, my issue is that I cant remove a row by the _id because the _id contains an obj ObjectId, that's the row in the db,

{
    "_id" : ObjectId("541ec60e41b46b841adde31e"),
    "name" : "TT"
}

and this is how I'm trying to remove it,

db.books.remove({ _id: book_id}, function(err, delete) {
    if(err)
        console.log("ERROR!", err);

    console.log("deleted  ", delete);
});

I've no idea how to pass the book_id so the query will run as expected, hope you guys will be able to help me find a solution for this one. thanks!

Convert book_id to an ObjectId first:

var ObjectId = require('mongodb').ObjectID;

...

db.books.remove({ _id: ObjectId(book_id) }, ...);
