node.js mongodb select document by _id node-mongodb-native
With native_parser:false
:
var BSON = require('mongodb').BSONPure;
var o_id = BSON.ObjectID.createFromHexString(theidID);
With native_parser:true
:
var BSON = require('mongodb').BSONNative;
var o_id = BSON.ObjectID.createFromHexString(theidID);
var mongo = require('mongodb');
var o_id = new mongo.ObjectID(theidID);
collection.update({'_id': o_id});
This the approach that worked for me.
var ObjectId = require('mongodb').ObjectID;
var get_by_id = function(id, callback) {
console.log("find by: "+ id);
get_collection(function(collection) {
collection.findOne({"_id": new ObjectId(id)}, function(err, doc) {
callback(doc);
});
});
}
now you can just use this:
var ObjectID = require('mongodb').ObjectID;
var o_id = new ObjectID("yourObjectIdString");
....
collection.update({'_id': o_id});
