Write to rails console

Question

When I want to try or debug smthing I run rails console and do some stuff there  I can print some text or variables from code by raising exception with raise  blablabla   Question  How I can just write to rails console without exception raising  and obvious breaking code execution  like a simple logger info  blah

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!!!"

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

puts or p is a good start to do that   p  asd            gt   asd  puts  asd         gt  asd   here is more information about that  http   www ruby-doc org core-1 9 3 ARGF html

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
