Hello !
I had to deploy a rails 3 app on heroku
app is using bare sass, and it is already known as a hassle (http://blog.heroku.com/archives/2009/8/18/heroku_sass/)
so I looked for what was said on web, and decided to offer serve sassed css from tmp dir, using Rack::Static, as first option (considering another one at the same time)
#1
First try was to drop in config/initializers/sass.rb
Sass::Plugin.options[:css_location] = ‘tmp/stylesheets’
Rails::Application.middleware.use Rack::Static, :root => ‘tmp’, :urls => [‘/stylesheets’]
It works on development env, generating tmp/stylesheets/base.css then rack it up
On production, what I saw was :
-
server runs for 30s
-
client receive empty base.css
ouch!, ugly rendering!
So same rack stack produced different behaviors on development and production
#2
moving Rack::Static from initializer to top of config.ru produce consistent behavior on both env
I retained this one now
Does someone has a clue on why #1 produce different behaviors in development and production ?
Curious, Thierry
