So in python/django I can just put the line print 'something' in my code and something will get printed to the console. How do I do this in Rails? I'm on Mac using Pow as my development server.
Pow stores log files for your apps in ~/Library/Logs/Pow/apps. You can cd to this directory in your terminal and then run tail -f my_app.log to view your log as it updates (-f is for 'follow'). You can then print from your ruby/rails scripts using the puts command and the output will appear in this log file.
