Rails: How to use default layout if It layout file is missing

How to use default layout if It layout file is missing?

I have folder layouts/themes/ that contains themes, but I want to load default theme if file is not exist.

I tried to set rescue_from ActionView:MissingTemplate, with => ... but I can't set layout in such way.

So the best solution that I found is: layout :layout_by_resource

def layout_by_resource
  layout_name = "themes/" + current_theme
  File.exists?(Rails.root + "app/views/layouts/" + (layout_name + ".html.erb")) ? layout_name : "application"
end

Is there better solution for such purpose?

In Rails layouts are stored in app/views/layouts and default layout name is application.html.erb and it is used if there is no layout that's name correspond with controller name. For example, photos controller would have photos.html.erb layout.

For more details look here (section 2.2.13)
