Print on console (rails s)

Question

I'm creating a new app using Rails 5.

How can I debug using a Rails 5 app.

I mean my purpose is only to write on console when starting puma on development environments.

I have set

config.logger = Logger.new(STDERR)
config.log_level = :debug

but logger.debug "app" in my controllers seems not to be useful.

Has anyone try to write on server output with Rails 5 ?

Regards,

我还没试过过rails 5，但这篇博文看起来好像可以帮到你：
