安装

Ruby代码 gem install jammit

gem install jammit

Ruby代码 #environment.rb config.gem "jammit"

#environment.rb
config.gem "jammit"

Rails2 需要修改config/routes.rb添加路径，Rails 可不用
Ruby代码 ActionController::Routing::Routes.draw do |map| ... Jammit::Routes.draw(map) ... end

ActionController::Routing::Routes.draw do |map|
...
Jammit::Routes.draw(map)
...
end

配置
Ruby代码 #config/assets.yml embed_assets: on rubyscripts: workspace: - public/rubyscripts/vendor/jquery.js - public/rubyscripts/lib/*.js - public/rubyscripts/views/**/*.js - app/views/workspace/*.jst stylesheets: common: - public/stylesheets/reset.css - public/stylesheets/widgets/*.css workspace: - public/stylesheets/pages/workspace.css empty: - public/stylesheets/pages/empty.css

#config/assets.yml
embed_assets: on

rubyscripts:
workspace:
- public/rubyscripts/vendor/jquery.js
- public/rubyscripts/lib/*.js
- public/rubyscripts/views/**/*.js
- app/views/workspace/*.jst

stylesheets:
common:
- public/stylesheets/reset.css
- public/stylesheets/widgets/*.css
workspace:
- public/stylesheets/pages/workspace.css
empty:
- public/stylesheets/pages/empty.css

使用
Ruby代码 <%= include_stylesheets :common, :workspace, :media => 'all' %>
<%= include_rubyscripts :workspace %>

<%= include_stylesheets :common, :workspace, :media => 'all' %>
<%= include_rubyscripts :workspace %>

如果是开发环境，不想重启加载
Ruby代码 ＃ ApplicationController before_filter { Jammit.packager.precache_all } if Rails.env.development?

＃ ApplicationController

before_filter { Jammit.packager.precache_all } if Rails.env.development?

还有一些不错的配置，可以参照使用。
