从/shopqi/app/views/layouts/README.textile文件可以看出（如下代码所示），一共分这几大块儿

各个layout使用场景:

# shopqi: 官网
# admin: 后台管理
# theme: 主题商店
# shop/checkout: 前台商店支付页面
# application.html.haml 用户登录

先看前端展示页与相关routes：

routes.rb

  constraints(Domain::Shopqi) do
    scope module: :shopqi do # 官网
      ......
      root to: "home#page"
      scope "/tour" do # 功能演示
        get '/'        , to: 'home#tour'    , as: :tour_intro
        get '/store'   , to: 'home#store'   , as: :tour_store
        get '/design'  , to: 'home#design'  , as: :tour_design
        get '/security', to: 'home#security', as: :tour_security
        get '/features', to: 'home#features', as: :tour_features
      end
      ......
    end

constraints限定在Shopqi文件夹中

scope module: :shopqi controller的路径前面加上shopqi

scope "/tour" do 地址栏的路径前面加上/tour

都把矛头指向了controllers/shopqi/home/home_controller.rb,让我们来看看：

  layout 'shopqi'
  expose(:plan_types){KeyValues::Plan::Type.all.reverse}

这是前两行的内容，第一行指定了布局，第二行用了decent_exposure插件和active_hash插件（见下面）。它返回plan_types,里面装的是顾客需要购买的商店类型基本信息（旗舰版，免费版...），sign_up的页面用到了这个变量

其它的静态页面跳转没有体现在home_controller中，直接跳过去了。

插件的使用：

• decent_exposure：使你的controller中的变量变得极其简洁。railscast有免费课程讲解
• active_hash：一个只读的ActiveRecord-esque基类,允许你使用一个散列,一个Yaml文件或一个自定义文件作为数据源
  • model/key_value.rb运用active_hash写入了项目需要的硬编码

        %a(href="/services/signup/new/free")
      %th.table-col-1.professional
        %a(href="/services/signup/new/professional")
      %th.table-col-2.business
        %a(href="/services/signup/new/business")
      %th.table-col-3.unlimited
        %a(href="/services/signup/new/unlimited")

      get '/signup'   , to: redirect('/services/signup')
      get '/login'    , to: 'home#login'
      scope "/services/signup" do
        get '/'                    , to: 'home#signup'                               , as: :services_signup
        # :confirmations, :omniauth_callbacks, :passwords, :registrations, :sessions, :unlocks
        devise_for :user, skip: [:sessions, :confirmations, :passwords], skip_helpers: true
        devise_scope :user do
          get "/new/:plan"         , to: "registrations#new"                         , as: :signup
          get "/check_availability", to: "registrations#check_availability"
          post "/user"             , to: "registrations#create"                      , as: :signup_user
          post "/verify_code"      , to: "registrations#verify_code" # 获取手机校验码
        end
      end

registrations#new 跳转到 views/shopqi/registrations/new.html.haml 里面点击注册后

跳转到/shopqi/app/views/admin/home文件夹下，将显示此文件夹下一系列页面
