file uploads with express and node.js

uploadapp.js

// middleware
app.use(express.bodyParser({ keepExtensions: true, uploadDir: __dirname + "/public/uploads" }))

// later
app.get('/photos', uploadFile, addPhoto)

// file is automatically saved to /public/uploads, let's just set 
function uploadFile(req, res, next) {
	if (req.files) {
		req.body.url = "http://myawesomesite.com/" + req.files.file.path.split("/").slice(-2).join("/")
		req.body.path = req.files.file.path.split("/").slice(-2).join("/")
	}
	next()
}

// file upload is optional, it could have come before
function addPhoto(req, res) {
	var eventId = req.param("eventId")
	var e = req.body
	var userId = e.userId ? new ObjectId(e.userId) : undefined
	var photo = new Photo({
		  userId        : userId
		, eventId       : new ObjectId(e.eventId)
		, latitude      : e.latitude
		, longitude     : e.longitude
		, path          : e.path
		, url           : e.url
		, type          : e.type
		, title         : e.title
		, description 	: e.description
	})
	
	photo.save(function(err) {
		if (err) return res.send(err.message, 500)
		res.json("OK")
	})
}

@anwu I'd say it looks like a MongooseJS model object, but I could be wrong.
