Rails - how to disable all console logging?

You can turn off the SQL queries. I know they take a lot of room.

Disable Rails SQL logging in console

Try changing the log level, which is info by default.

From the Guides: http://guides.rubyonrails.org/debugging_rails_applications.html#log-levels

Change the log level in config/environments/development.rb, and/or testing.rb:

config.log_level = :error

The log levels available are: :debug, :info, :warn, :error, :fatal, and :unknown, which correspond to the integers 0-5.
