It depends how your are running your rails application. If you are using
script/server, the puts will output in the server output (in the
console) when you access a page. Some setups will crash if they see a
“puts” in your code.

It sounds like you are trying to do some debugging with these print
statements … I suggest using breakpointer … simply put a call to
“breakpoint” in your code where you want to break, and start
script/breakpointer in a new shell … this will give you an irb console
to your rails application at the breakpoint.

mhhh seams not that easy…

Andreas,

puts is for console output. It won’t print anything to a page in Rails.
You use it in ruby scripts executed from the console.
In Rails, all rendering is done in the .rhtml files, so anything that
needs to be output-ted has to be in there.

My best advice is don’t use puts in Rails code. It leads to application
errors, at least in Apache/FCGI.

Use logger.info “whatever you want”. It will show up in your
development.log or production.log, depending on you RAILS_ENV.
