How do I configure logging in a Rails application?

To configure logging in a Rails application, you can modify the config/environments/*.rb files. Each environment (development, test, production) has its own configuration.

What are the different log levels I can use?

Rails supports several log levels: debug, info, warn, error, fatal, and unknown. You can set the desired level in your environment configuration.

Can I log to a file instead of the console?

Yes, you can log to a file by setting the config.logger option in your environment file. For example, you can use config.logger = ActiveSupport::Logger.new('log/my_custom_log.log').

How do I format the log output?

You can customize the log format by creating a custom logger or using a formatter. For example, you can set config.log_formatter to a custom formatter class.
