Express always wants to render a 'layout' view

[Arunjit Singh]

Started using jade with express.

After creating the default app and testing if it worked (which it did), I removed the layout.jade file and put some more content in index.jade and created a new jade template. After running the app again, Express errors out with code 500:

500 Error: failed to locate view "layout"

[at http://localhost:3000/]

But the view "layout" is never called! It is simply:

app.get('/', function(req, res){

    res.render('index', {

        title: 'Testing Express'

        body: 'This works fine. Now start making the app!'

    });

});

Does express require a layout.jade view always?

nope it's just a default since most apps will have some common stuff. You just need to pass a local { layout: false }, but there are several ways to do that:

   res.render(view, { layout: false })

   res.local('layout', false)

   app.locals({ layout: false }) // app level default

   app.set('view options', { layout: false }) // pretty much same as above

currently the app-level locals take precedence, and while "view options" reads better I might remove it in 3.x since it's extraneous

Thanks!

I just re-read the guide on expressjs.com, and found app.set('view options', {layout: false}), which seems to fix layout always wanting to crop up.

App-level locals, app.locals, are always applied to views? Is there a way to make each view have completely independent locals?

PS: is there a good place to learn about jade? (I'm making syntax errors all over the place)

they are just merged, so you can still pass whatever to res.render() per request, but it's nice to have app-level locals too like little date helper functions etc
