1.gemFile


在rails 4 之后没有grop 了 要记得哦


# group :assets do
gem 'sass-rails', '~> 4.0.0'
gem 'coffee-rails', '~> 4.0.0'    
gem 'uglifier', '>= 1.3.0'
# end
# 页面渲染
gem 'jquery-rails'  #这个
gem 'execjs'      # 记得这个
gem 'turbolinks'


2.在 config/application.rb 记得 application 文件 不要对了哦

config.assets.precompile << Proc.new do |path|
      if path =~ /\.(css|js|scss|png|jpg|gif|json)\z/
        full_path = Rails.application.assets.resolve(path).to_path
        app_assets_path1 = Rails.root.join('app', 'assets').to_path
        app_assets_path2 = Rails.root.join('public', 'assets').to_path
        app_assets_path3 = Rails.root.join('vendor', 'assets').to_path


        if full_path.starts_with? app_assets_path1
          true
        else
          if full_path.starts_with? app_assets_path2
            true
          else
            if full_path.starts_with? app_assets_path3
              true
            else
              false
            end
          end
        end
      end
    end


3.秘诀 config/environment/production.rb


   config.action_controller.relative_url_root = '/discount_service'  #是用来 有用啊
   config.serve_static_assets = true
   # Compress JavaScripts and CSS.
  config.assets.compress = true
   config.assets.js_compressor = :uglifier
   config.assets.css_compressor = :sass

4.最后要记得这个 啊 

RAILS_ENV=production rake assets:precompile
