Docpad : show error/success message on contact form

问题

I added a route in my docpad.coffee file to handle form submissions, that I validate using the express-validator middleware. Now depending on the validation, I want to redirect the users to the same contact page but displaying either a success message when validation is successful (here I'll send an email), or display the error messages.

I didn't manage to pass the validation message to the template to display it. I tried almost all combinations of dynamic: true/false, res.locals = validationMessages, res.sessions = validationMessages, res.templateData = validationMessages with no success.

Furthermore, adding dynamic: true made the changes to the content not appear at all, whatever refresh strategy I use (private mode, cleaning cache, relaunching Docpad, refreshing without cache, etc.). I should probable file a bug about it.

How to ?

I'm using Docpad 6.53.0 (latest to date), node 0.10.15, on OS X 10.8.4

I cheated on this one a bit by appending a hash to the redirect url (eg: "www.mywebsite.com/#messagesent"). I then use client side javascript to read the hash and then show the appropriate message. Something like this:

if (location.hash == "#messagesent") {  
    $('#message-sent').show();
    setTimeout(function () {
        $('#message-sent').fadeOut(1000);
    }, 1000);
}

Not quite what you were asking though :)
