Undefined method flash in the view of node.js - node.js

Question

Problem in accessing flash messages on view in node.js
In my Controller
this.req.flash('info','successfully submited');
this.redirect("/home");
In my home view I am not able to get flash messages as
req.flash('info');
EDIT
In controller
self.req.flash('message','hello');
In view
<%= req.flash('message) %>
In server.js
app.configure(function (){
app.use(express.cookieParser());
app.use(express.session({ secret:'yoursecret',cookie: { maxAge: 24 * 60 * 60 * 1000 }}));
app.use(passport.initialize());
app.use(locomotive.session());
app.use(flash());
app.use(passport.session());
app.use(app.router);
app.dynamicHelpers({ messages: require('express-messages') });
});
I have the locomotive framework.

Please see tempdata example https://github.com/MKxDev/TempData
var tempData = require('tempdata');
var app = express();
app.configure(function() {
...
// This has to appear BEFORE the router
app.use(express.cookieParser());
app.use(express.session({ secret: 'your_super_secret_session_key' })); // please change this!
app.use(tempData);
...
});
...
// Routes
app.get('/', function(req, res) {
// Retrieve tempData value here. It won't exist unless the request
// was redirected
var tempVal = JSON.stringify(req.tempData.get('test_val'));
res.render('index', { title: 'Express', temp: tempVal });
});
app.post('/', function(req, res) {
// Set tempData value here
req.tempData.set('test_val', { x: 'Hello World!' });
res.redirect('/');
});

Move your app.use(flash()) higher in the order...see below. Flash needs to be initialized before passport so that flash is recognized and available to passport.
app.configure(function (){
app.use(express.cookieParser());
app.use(express.session({ secret:'yoursecret',cookie: { maxAge: 24 * 60 * 60 * 1000 }}));
app.use(flash()); // moved this up a few lines
app.use(passport.initialize());
app.use(locomotive.session());
app.use(passport.session());
app.use(app.router);
app.dynamicHelpers({ messages: require('express-messages') });
});
