Specifying a layout file in Sails.js when calling sails.renderView

I'm using the sails helper method sails.renderView to render a view into a string that is then used in an email, like so:

sails.renderView('emails/booking', emailData, function (err, view) {
    emailService.send(user.email, view);
});

Is it possible to specify a layout file when rendering a view in this way? I'm using ejs template engine.

It doesn't look like I can use the view config (config/views.js) as it's route based.

I had a look at the render function in sails/lib/hooks/views/render.js and it looked like the layout file to use could be passed in the options object but when I did, no view is returned.

EDIT: Sorry I missed that this is being generated outside the regular request/response context. Answer changed to reflect that.

I had a poke through the sails code, particularly the render engine

/**
 * sails.hooks.views.render(relPathToView, options, cb_view)
 *
 * @param {String} relPathToView
 *              -> path to the view file to load (minus the file extension)
 *                  relative to the app's `views` directory
 * @param {Object} options
 *              -> options hash to pass to template renderer, including locals and locale
 * @param {Function} cb_view(err)
 *              -> called when the view rendering is complete (response is already sent, or in the process)
 *                  (probably should be @api private)
 * @api public
 */
... lots of code ... 
  // if local `layout` is set to true or unspecified
  // fall back to global config
  var layout = options.layout;
  if (layout === undefined || layout === true) {
    layout = sails.config.views.layout;
  }

Turns out you can set the layout as part of the options object you pass into sails.renderView()

So if you have an email template emailLayout.ejs, you can use it by adding this line to you controller like so:

emailData.layout = '/emailLayout';
sails.renderView('emails/booking', emailData, function (err, view) {
    emailService.send(user.email, view);
});

Big caveat, this explicitly only works for ejs templates. I haven't tested this, so let me know how it goes
