Using Compass on Heroku: / tmp for styles remotely and locally

I am currently using Compass with Heroku, using this configuration recommended in the Heroku Knowledge Base. Heroku has a read-only file system, so compiled style sheets need to be stored in / tmp. This works great on Heroku; locally, however, Rails expects to find stylesheets in / public / stylesheets (when called through = stylesheet_link_tag 'screen.css', :media => 'screen, projection').

To solve the problem, I created symbolic links in / public / stylesheets using ln -s tmp/stylesheets/screen.css public/stylesheets/screen.cssand it seems to work.

Is there a way to solve this problem without using symbolic links, perhaps by changing some configuration in Rails? I poked without much success.

Here is my config / initializers / compass.rb:

require 'compass'
require 'compass/app_integration/rails'
Compass::AppIntegration::Rails.initialize!

# Required for Heroku:
require 'fileutils'
FileUtils.mkdir_p(Rails.root.join("tmp", "stylesheets"))

Compass::AppIntegration::Rails.initialize!

Rails.configuration.middleware.delete('Sass::Plugin::Rack')
Rails.configuration.middleware.insert_before('Rack::Sendfile', 'Sass::Plugin::Rack')

Rails.configuration.middleware.insert_before('Rack::Sendfile', 'Rack::Static',
    :urls => ['/stylesheets'],
    :root => "#{Rails.root}/tmp")

And here is my config / compass.rb:

project_type = :rails
project_path = Compass::AppIntegration::Rails.root

# Set this to the root of your project when deployed:
http_path = "/"

# Necessary for Heroku (original commented out:
css_dir   = 'tmp/stylesheets'
#css_dir = "public/stylesheets/compiled"

sass_dir  = 'app/views/stylesheets'

environment = Compass::AppIntegration::Rails.env
