我相信rails在生产中的默认行为是不输出所有部分的渲染.这应该登录开发,但不能生产.
但是,我在生产中看到这个,我不知道如何删除它.我的日志太吵了我的生产环境是Heroku运行Unicorn并使用Papertrail查看我的日志.我知道Unicorn使用日志做了一些蛮横的东西,并让他们正常工作,首先我不得不将它添加到我的production.rb中：
config.logger = Logger.new(STDOUT)
config.logger.level = Logger.const_get('INFO')
(在这里解释：http://help.papertrailapp.com/kb/configuration/unicorn)
但即使使用log_level INFO,我在所有日志中看到巨大的块：

解决方法
对于Rails 4(至少)：
请尝试在您的config / environments / development.rb中
config.action_view.logger = nil
