ruby - Rails 3 缓存不起作用。达利

Question

development.rb缓存配置

  config.action_controller.perform_caching = true
  config.cache_store = :dalli_store, 'localhost:11211',
    { :namespace => APP_NAME, :expires_in => 3.month, :compress => true }

production.rb 缓存配置

   config.action_controller.perform_caching = true
   config.cache_store = :dalli_store, 'localhost:11211',
     { :namespace => APP_NAME, :expires_in => 3.month, :compress => true }

在控制台中

rails c production
Loading production environment (Rails 3.2.3)
1.9.3-p125 :001 > Rails.cache.write 'res', "Hello World"
 => true 
1.9.3-p125 :002 >  Rails.cache.read 'res'
 => nil 
1.9.3-p125 :003 > 

为什么？

如果您以这种方式定义到期，memcached 的限制为 30 天 - Memcache 最大密钥到期时间
