我正在获取缓存：我的Rails 3.2应用程序的[GET /] miss错误消息.

我使用nginx作为unicorn服务器的代理,我使用capistrano进行部署.当我启动服务器时,我会遇到很多像上面那样的重复错误. Capistrano肯定会在部署期间预编译资产.我在下面包含配置文件(抱歉是详细的).

找出错误的任何想法或至少暗示？

application.rb中

config.assets.enabled = true

production.rb

# Disable Rails's static asset server
# (Apache or nginx SHOULD already do this BUT THEY DON'T)
config.serve_static_assets = true

# Don't fallback to assets pipeline if a precompiled asset is missed
# If I disable this I don't get assets served at all
config.assets.compile = true

deploy.rb

  end
  task :start do
    run "cd #{deploy_to}/current && bundle exec unicorn -c #{unicorn_conf} -E #{rails_env} -D"
  end
  task :stop do

  end
end

解决方法:

我在网络服务器日志中注意到类似的消息,注意到我必须让Rails知道我没有在config / environments / production.rb中使用缓存

config.action_controller.perform_caching = false
