Re: Locals - Every Request

[greelgorke]

with res.set you set Header fields.

what you want is res.locals or app.locals

Sorry if this is a stupid question, still learning.

But is there a way to set a local on every request?  For variables in the Layouts (in the case of jade)

I'm trying:

app.use(function (req, res, next) {
    res.set({ someValue: "1" });
    next();
});

But I still get a reference error within the view.  Am I just doing this wrong? Or is this not possible?

I thought I'd tried that previously.

So towards the top I have:

app.use(function (req, res, next) {
    res.locals.currentTime = new Date();
    next();
});

app.get('/', routes.index);

Then in routes.index I have:

exports.index = function (req, res) {
    res.render('index');
/*
    I *did* have the following, which I thought was causing the problem.
    res.render('index', { title: "Welcome" });
*/
};

And in my view I simply have
=currentTime

But I still get the following reference error that currentTime is undefined:
currentTime is not defined

Actually, I got it to work by doing this:

app.use(function (req, res, next) {
    res._locals = { 
        currentTime: new Date()
        };
    next();
});

Is that a completely wrong way to handle this?
