ActionView: render a layout not in app/views?

Hey there,
I have a problem.

class ApplicationController
  layout :determine_layout

  def determine_layout
    "../../public/sites/#{@site.code}/application"
  end
end

in rails2.0 this worked, but it was clearly a hack.

I tried to fix it in a few ways;

1. symlink public/sites -> app/views/layouts/sites
- this breaks because the Dir.glob used to find view files doesnt work
for subfolders of a symlink

2. set ApplicationController.view_paths << "public/sites"
- this doesnt quite seem to work.

3. manually fix rails and work out the best way to patch it for 2.2.1
- this seemed to work, but isn't quite plugin-able as a fix

mostly I'm wondering,
what is the right way to do this?

Quite often I'm tasked with doing something very similar. Check out my
solution:

class ExperiencesController < ApplicationController
  self.view_paths << File.join(RAILS_ROOT, "cms", "experiences")

  def show
    render :layout => "1/layout"
  end
end

requiring a folder structure like:
RAILS_ROOT/
  app/
  cms/
    experiences/
      1/
        layout.html.erb
  config/
  ...

Does that help?

Hey thanks andrew,
that's the same thing I'm trying to achieve,
although the code as such won't quite work in Rails 2.1.1

it'll give you errors about "found a view path that is not in the right
format"

the correct way is
  append_view_path(...)

and you pointed out my error

I was doing;
  append_view_path("public/sites")

while actually what is required;
  append_view_path(File.join(Rails.root, "public", "sites"))

works great, it seems.
Thanks.
