升格Rails 3.1 production的一点心得

升级Rails 3.1 production的一点心得
刚刚和朋友聊起来相关的东西，赶紧纪录下来
主要就是打开了asset pipeline和用了html5

1新建Rails 项目，有home controller，index action 和root路由并且删除public下index.html和views/layouts/application.html.erb


2添加或修改以下Gemfile

gem 'rails', '~> 3.1.0'
gem 'unicorn'
group :assets do
  gem 'compass', "~> 0.12.alpha.0"
  gem 'sass-rails', "~> 3.1.0"
  gem 'coffee-rails', "~> 3.1.0"
  gem 'uglifier'
  gem 'compass-html5', :git => 'https://github.com/sporkd/compass-html5.git'
  gem 'html5-rails', :git => "https://github.com/sporkd/html5-rails.git"
end

#application.rb
config.assets.precompile += %w( polyfills.js )

3运行 

rails g html5:install

生成  文件

4 创建如下文件

Rails.configuration.sass.tap do |config|
  config.load_paths << "#{Gem.loaded_specs['compass'].full_gem_path}/frameworks/compass/stylesheets"
end

5 执行

RAILS_ENV=production bundle exec rake assets:precompile

6 执行

unicorn -E production

或

rails s -e production
