Use a variable in a Jade include

Question

I'm working with Jade and Express and I would like to use a variable in my include statement. For example:

app.js

app.get('/admin', function (req, res) {
  var Admin = require('./routes/admin/app').Admin;

  res.render(Admin.view, {
    title: 'Admin',
    page: 'admin'
  });
});

layout.jade

- var templates = page + '/templates/'

include templates

When I do this I get the error EBADF, Bad file descriptor 'templates.jade'

I even tried

include #{templates}

to no avail.

Answer 1

AFAIK JADE does not support dynamic including. What I suggest is to "include" outside the template, i.e.

app.js

app.get('/admin', function (req, res) {
    var Admin = require('./routes/admin/app').Admin;
    var page = 'admin';

    var templates = page + '/templates/';

    // render template and store the result in html variable
    res.render(templates, function(err, html) {

        res.render(Admin.view, {
            title: 'Admin',
            page: page,
            html: html
        });

    });

});

layout.jade

|!{ html }
