How to redirect user to home page with his ID after authentication using Node.js and Passport? -

i have started learning node.js go easy on me :p

i'm using passport autenticate user. user needs redirected home page id url parameter after successful authentication, example:

 /home?id=325346546 

here part of routes.js

    // process login form     app.post('/', passport.authenticate('local-login', {         successredirect : '/home?id='+req.user._id, //error because 'req' isn't declared         failureredirect : '/',         failureflash : true     })); 

this idea, want pass id parameter url.

i have tried putting a

function(req, res) { } 

but didn't work. appreciated.

    // process login form     app.post('/', function(req, res, next) {       passport.authenticate('local-login', {failureflash:true}, function(err, user, info) {        if (err) { return next(err); }        if (!user) { return res.redirect('/'); }       req.login(user, function(err) {         if (err) { return next(err); }        return res.redirect('/home?id=' + user._id);      });     })(req, res, next);     });
