Querying a MongoDB based on Mongo ID in a node.js app

Question

I\'m using a node.js and mongodb, and I\'m trying to query the database based on the mongo generated ID using the following:

    collection.findOne( {_id:doc         


        

Answer 1

The MongoDb is an object not a string. To convert my string I used:

    var id = require('mongodb').ObjectID(doc._id);

This converts my string into a mongo ObjectId and matches the _id in the db!
