How do I use the regular rails logger in a rails app in a class that  
is does not inherit from active record?

Do you want to log from a controller? If so, something like this in  
application.rb is handy:

def log(message)  
logger.info “Any\_prefix\_you\_want\_to\_grep: #{message.to\_s}”  
end

If you want to log from somewhere that’s not inheriting any part of  
the rails stack, I’ll let someone else answer…
