Disable Rails SQL logging in console

Solution 1:

To turn it off:

old_logger = ActiveRecord::Base.logger
ActiveRecord::Base.logger = nil

To turn it back on:

ActiveRecord::Base.logger = old_logger

Here's a variation I consider somewhat cleaner, that still allows potential other logging from AR. In config/environments/development.rb :

config.after_initialize do
  ActiveRecord::Base.logger = Rails.logger.clone
  ActiveRecord::Base.logger.level = Logger::INFO
end
