The EASIEST thing is to load the Footnotes plugin. Search for it at
Then load it using the standard plugin method. From your project
Footnotes gives you extra goodness if you’re using TextMate – which
you should anyway if you’re trying to learn or develop in RoR on a
Mac. I’m PRETTY sure it works without TextMate.
What it does is automatically place ruby-debug like information on the
bottom of each rendered page. Here’s what it looks like on my machine:
Show: Session | Cookies | Params | Log | General Debug
Click on the link to show whatever and there you are! (The first line,
Edit: won’t work without TextMate.) All this automatically turns off
when you move to Production mode.
