Hide rendering of partials from rails logs

Question

I believe the default behavior of rails logging on production is to not output the rendering of all partials. This should log in development but not on production.

However, I'm seeing this in production and I'm not sure how to remove it. My logs are too noisy. My production environment is Heroku running Unicorn and using Papertrail to view my logs. I know Unicorn does some wonky stuff with logs and to get them working properly in the first place I had to add this to my production.rb:

  config.logger = Logger.new(STDOUT)   config.logger.level = Logger.const_get('INFO') 

( Explained here: http://help.papertrailapp.com/kb/configuration/unicorn )

But even with log_level INFO I'm seeing huge blocks of these in all my logs:

For Rails 4 (at least):

Try this in your config/environments/development.rb

config.action_view.logger = nil
