trying to a a /file-upload path to the node-cella example project to put images directly onto the mongodb, added modules "connect-multipart-gridform" "gridform" and "gridfs-stream"

server.js

var express = require('express'),
	path = require('path'),
	http = require('http'),
	wine = require('./routes/wines'),
	cup  = require('./routes/cups');
var Grid = require('gridfs-stream');	
var mongo = require('mongodb');
var Server = mongo.Server,
    Db = mongo.Db;	
var server = new Server('localhost', 27017, {auto_reconnect: true});
var db = new Db('winedb', server, {safe: true});
db.open(function(err, db) {
    if(!err) {
        console.log("Connected to 'winedb' database");
        db.collection('fs', {safe:true}, function(err, collection) {
            if (!err) {
                console.log("The 'fs' collection doesn't exist. Creating it with sample data...");
				var multipartoptions = { db: db, mongo: mongo };
				app.use(multipart(multipartoptions));
            }
        });
    }
});

var multipart = require('connect-multipart-gridform');
var formidable = require('formidable');

var app = express();

app.configure(function () {
    app.set('port', process.env.PORT || 3000);
    app.use(express.logger('dev'));  /* 'default', 'short', 'tiny', 'dev' */
	app.use(express.static(path.join(__dirname, 'public')));
	//app.use(multipart(multipartoptions));
});

app.get('/wines', wine.findAll);
app.get('/wines/:id', wine.findById);
app.post('/wines', wine.addWine);
app.put('/wines/:id', wine.updateWine);
app.delete('/wines/:id', wine.deleteWine);

app.get('/cups', cup.findAll);
app.get('/cups/:id', cup.findById);
app.post('/cups', cup.addCup);
app.put('/cups/:id', cup.updateCup);
app.delete('/cups/:id', cup.deleteCup);

app.get('/lastfile'), function(req,res){
	var readstream = gfs.createReadStream('crud.png');
	readstream.pipe(res);
	//res.send(files);
}

app.post('/file-upload', function(req, res){
	var form = multipart.gridform({db:db,mongo:mongo});
	form.parse(req, function (err, fields, files) {
    if (err) {
        console.log('Error Uploading: ' + err);
        res.send({'Error':err});
    } 
		else {
			var thumb = files.thumbnail;
			console.log(thumb);
			console.log(form);
			console.log(form.gridfsStream);
			console.log(Grid);
			//gfs.createReadStream(thumb.name);
			//readstream.pipe(res);
			res.send(thumb);
    }
	});
});


http.createServer(app).listen(app.get('port'), function () {
    console.log("Express server listening on port " + app.get('port'));
});
