First look in log/development.log and see what is added when you click
the delete link. There you should see which action is called, the
parameters, and what happens next. If that all looks correct then you
can insert simple debug statements into your code using code such as
logger.info "some_varlable is #{some_variable.inspect}"
the result will appear in development.log

However I suggest that to get started you might be better to work
right through the tutorial at railstutorial.org (which is free to use
online). That can be done using an IDE in the cloud9 so you are not
reliant on s/w installed on your PC.
