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?
