Actionpack页面缓存每个请求上呈现的视图

Question

我尝试使用Actionpack页面缓存与我的静态页面。 如果我理解这个工作'Actionpack页面缓存'是第一个请求到达rails。渲染的意见，和Html存储在缓存公共/部署/ ...

第二个类似的请求没有达到铁路。视图不会渲染。一个页面将从缓存中获取。

但在日志中它看起来完全不同。

在视图将呈现和缓存页面overwrited所有请求。

我用： 轨4.0.0

的JRuby

彪马服务器

生产模式

启动服务器 - RAILS_ENV =生产钢轨小号彪马

我production.rb

ResFm::Application.configure do 

     config.cache_classes = true 
     config.eager_load = true 
     config.consider_all_requests_local  = false 
     config.action_controller.perform_caching = true 
     config.cache_store = :dalli_store 

     config.assets.js_compressor = :uglifier 
     config.assets.css_compressor = :sass 

     config.assets.compile = false 
     config.assets.digest = true 
     config.assets.version = '1.0' 
     config.assets.debug = false 

     config.log_level = :info 
     config.i18n.fallbacks = true 
     config.active_support.deprecation = :notify 
     config.log_formatter = ::Logger::Formatter.new 

     # cache static pages 
     config.action_controller.page_cache_directory = "#{Rails.root.to_s}/public/deploy" 
     config.serve_static_assets = true 

     #CDN google servers 
     config.asset_host = 'http://resassets.appspot.com' 
    end 

在控制器I使用

caches_page :load_app 
def load_app 

end 

，这是一个根URL。

我的Gemfile

gem 'rails', '4.0.0' 
    gem 'activerecord-jdbcpostgresql-adapter', '~>1.3.0.beta2' 
    gem 'dalli' 
    gem 'jquery-ui-rails' 
    gem 'jquery-rails' 

    group :assets do 
     gem 'coffee-rails', '~> 4.0.0' 
     gem 'uglifier', '>= 1.3.0' 
     gem 'therubyrhino' 
     gem 'execjs' 
    end 

    group :development do 
     gem 'annotate' 
     gem 'puma' 
    end 

    gem 'dimensions-rails' 
    gem 'sass-rails', '~> 4.0.0' 

    group :production do 
     gem 'rack-cache' 
     gem 'actionpack-page_caching' 
    end 

请帮助我明白我做错了。

当使用页面缓存时，您应该指示您的网络服务器提供写入公共目录的缓存页面。这个想法是，如果您的请求的正常路径是/foo/bar.html，则应将缓存副本存储在Rails.root/public/foo/bar.html中。这样的请求永远不会击中你的Rails应用程序。

将存储路径更改为public/deploy时，应该注意将Web服务器指向该目录以便从那里提供文件。我不认为Puma会处理这个问题，所以你应该在前端服务器（如Apache或Nginx）中处理它。

话虽如此，页面缓存已从Rails 4中删除有很好的理由，预先你应该看看Russian Doll Caching，因为它更灵活和易于使用。
