Ruby on Rails

Hej Barney

The debugger call will stop the execution and drop you into the debugger - it's not from within your text editor - it's in the
terminal window where you run your app

Start your app with

rails server --debugger

or (if your running rails < 3.0 )

script/server --debugger

Cheers,
Eric
