copied!<p>For anyone's convenience, I adopted Richard's solution in my project and created a simple ruby script that replaces asset links in the static HTML error / maintenance pages. It is deliberatery NOT a rake task so that it is as fast as possible. It has no Rails depenency anyway, other than that it has to be run from the rails root directory.</p> <pre><code>#!/usr/bin/env ruby require 'yaml' GLOBS = %w(public/errors_source/*.html) MANIFEST = "public/assets/manifest.yml" manifest = YAML::load(File.open(MANIFEST)) GLOBS.each do |glob| Dir.glob(glob).each do |file| next unless File.file?(file) contents = File.read(file) manifest.each do |asset, compiled_asset| contents.gsub!(asset, "/assets/#{compiled_asset}") end File.open(file.gsub('errors_source/',''), 'w') do |outfile| outfile.write(contents) end end end </code></pre> <p>The script expects the static HTML error/maintenance pages to live under the <code>errors_source</code> directory and copies them (with assets replaced for their hashed versions) to the rails root directory. </p> <p>A sample maintenance page then may look like this (notice the CSS asset link and logo image - these assets are simply shared with the main rails code):</p> <pre><code><html> <head> ... <link href="application.css" media="screen" rel="stylesheet" type="text/css"/> </head> <body> ... <a href="/"><img src="logo.png" width="161" height="61"/></a> ... </body> </html> </code></pre>
