In the below code i'm trying to fetch the user details from DB and save it to session. But unfortunately it doesn't work as i've expected, the data is not written into the session variable. I guess it's because of pass by value? Any workaround

exports.check = function(req,res,next){
    ..
    ..
    getUserFromDB(req);
}

function getUserFromDB(req){
    ..
    db.findOne(query,function(doc){
        req.session.user = doc;
    })
}

I think you are missing the callback call. Are you using express and mongodb? We should post full working examples :)

exports.check = function (req, res, next) {
  getUserFromDB(req, next);
};

function getUserFromDB(req, callback) {
  db.findOne({ _id: req.qs.id }, function (err, doc) {
    req.session.user = doc;
    callback(err);
  });
}

Also check for err, and also for null doc (not found).
