As other have said  you want to use either puts or p  Why  Is that magic   Actually not   A rails console is  under the hood  an IRB  so all you can do in IRB you will be able to do in a rails console  Since for printing in an IRB we use puts  we use the same command for printing in a rails console   You can actually take a look at the console code in the rails source code  See the require of irb

In addition to already suggested p and puts     well  actually in most cases you do can write logger info  blah  just as you suggested yourself  It works in console too  not only in server mode   But if all you want is console debugging  puts and p are much shorter to write  anyway

I think you should use the Rails debug options   logger debug  Person attributes hash     person attributes inspect   logger info  Processing the request     logger fatal  Terminating application  raised unrecoverable error       https   guides rubyonrails org debugging rails applications html
