blueprint/screen.css isn't precompiled

Question

I\'ve been following along Michael Hartl\'s excellent RoR Tutorial, but I\'m using RoR 3.1. I am a newbie to RoR 3.1 and need help related to assets pipeline. Here is my pro

Answer 1

You may want to precompile your assets on production as described above. And if you use capistrano you may do it after code update:

require 'bundler/capistrano'

after 'deploy:update_code' do  
  run "cd #{release_path}; RAILS_ENV=#{rails_env} bundle exec rake assets:precompile"
end

Answer 2

I added a reference to the blueprint stylesheets in my application.css file. This way, I do not have to change the layout to modify the stylesheets, I simply need to modify the application.css file, run rake assets:precompile, and restart the webserver (if webrick or similar).

My application.css currently looks like this:

/*
 * This is a manifest file that'll automatically include all the stylesheets available in this directory
 * and any sub-directories. You're free to add application-wide styles to this file and they'll appear at
 * the top of the compiled file, but it's generally better to create a new file per style scope.
 *= require_self
 *= require_tree ./blueprint
 *= require_tree . 
 */

Answer 3

From http://guides.rubyonrails.org/asset_pipeline.html#precompiling-assets

If you have other manifests or individual stylesheets and JavaScript files to include, you can add them to the precompile array

This means that in your config/environments/production.rb, you set

config.assets.precompile += %w( blueprint/screen.css blueprint/print.css )

or a catchall:

config.assets.precompile += %w( *.css *.js )

Answer 4

From my own experience with this problem, where I was also going through the excellent RoR tutorial by Michael Hartl, there was one step that I think might be left out at this point...

bundle exec rake assets:precompile    
git add public/assets
git commit -m "vendor compiled assets"
git push heroku

I found this here.
