    <p>I want to display a flash message after a user fails to sign in but I just can't get the variables to show up in my Jade views. </p> <p>I have some pieces, I know I have to use this in my app.configure():</p> <pre><code> app.use (req, res, next) -&gt; res.locals.session = req.session </code></pre> <p>And I'll set what the flash message is after the user POSTS the wrong password:</p> <pre><code> exports.postSession = (req, res) -&gt; users = require '../DB/users' users.authenticate(req.body.login, req.body.password, (user) -&gt; if(user) req.session.user = user res.redirect(req.body.redirect || '/') else req.session.flash = 'Authentication Failure!' res.render('sessions/new', {title:'New', redirect: req.body.redirect }) ) </code></pre> <p>I don't know how to access <code>res.locals.session</code> in my Jade file. I doubt I am setting everything up right. This question is a lot like this one: <a href="https://stackoverflow.com/questions/11580796/migrating-express-js-2-to-3-specifically-app-dynamichelpers-to-app-locals-use">Migrating Express.js 2 to 3, specifically app.dynamicHelpers() to app.locals.use?</a> but I still can't get it to work. It would be much appreciated if someone could show me just a simple example of setting values in res.local and accessing them in a view.</p> <p>p.s. I do know about connect-flash but I need to understand how to make things available in views. </p> <p>This is my app:</p> <pre><code>app.configure(() -&gt; app.set('views', __dirname + '/views') app.set('view engine', 'jade') app.use(express.bodyParser()) app.engine('.jade', require('jade').__express) app.use(express.methodOverride()) app.use(express.cookieParser()) app.use(express.session({ store: new express.session.MemoryStore({reapInterval: 50000 * 10}), secret: 'chubby bunny' })) app.use(express.static(__dirname + '/public')) app.use((req, res, next) -&gt; res.locals.session = req.session next() ) app.use(app.router) ) </code></pre>

    1. COp.p.s Also where is the documentation for this? I've been looking at [Migration guide](https://github.com/visionmedia/express/wiki/Migrating-from-2.x-to-3.x), the [Express site](http://expressjs.com/api.html), and [Connect website](http://www.senchalabs.org/connect/) yet I still can't figure it out... Maybe its just me but I feel like I'm struggling to learn ExpressJS because its documentation is so sparse.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
