"View Source" On Ruby Methods

I use this “view source” technique to spelunk Rails source all the time, so thought I’d share it:

Tracking down the definition of the update method seems easy enough. Given that we have all the Rails source files, we can just run a quick search for occurrences of def update . Trouble is, with that broad of a search you end up sifting through around 50 matches across 37 files. But of course we're only interested in the update method of an ActiveRecord model. Ideally we could go directly to the source of that method. Thankfully, Ruby 1.9 lets us do exactly that.
