Rails - Mar 2011 - Help overriding rescue_action_in_public in Rails 3

In Rails 2.3.x, you can override render_optional_error_file like so:
# ApplicationController.rb
protected
  def render_optional_error_file(status_code)
    render :template => "errors/500", :status => 500, :layout
=> ''application''
  end
However, Rails 3 no longer has render_optional_error_file. Instead, you need to
overriderescue_action_in_public, which I do:

# config/initializers/error_page.rb
module ActionDispatch
  class ShowExceptions

    protected    
      def rescue_action_in_public(exception)
        status = status_code(exception).to_s

        template = ActionView::Base.new(["#{Rails.root}/app/views"])
        if ["404"].include?(status)
          file = "/errors/404.html.erb"
        else
          file = "/errors/500.html.erb"
        end        
        body = template.render(:file => file)

        render(status, body)
      end

  end
end
This works, but does not use the application''s layout. However, if you
specify the layout path:

body = template.render(:file => file, :layout =>
"layouts/application") # line 15
I get an Error during failsafe response: ActionView::Template::Error.

Line 4 of application.html.erb:4 is:

<%= stylesheet_link_tag "app", "jquery-ui",
"jquery.fancybox", :cache => "all" %>
Whatever ActionView normally uses to render templates isn''t getting
loaded.

How can I get this to render my application layout?

Paul

please try specifying layout at the top of the controller like

layout ''application'', :only => action_name

Please refer to the rails documentation, there are other options like
:except, if this helps
