rails中的“puts”方法3

Question

I've been doing some development with rails 3 and I was wondering why calling the "puts" method doesn't output to standard out.

How do I get this back?

Answer 1

取而代之的puts ，使用logger.info ：

logger.info @collection.inspect

Answer 2

You can also use the standard ruby way by calling STDOUT << 'your output' . Method put is not a rails speciality, it comes with ruby. If you use rails, you can also rely on the logger object.
