Hi all,

I'm a 'ruby nubie' and otherwise unfamiliar with the ':eval' technique
it employs.

Are there any decent reference guides to it's use?

Alternatively, can anyone give me a quick explanation of what, when and
how to use it?

This for example, from an ajax scaffold im working on, makes little
sense to me (it doesn't help that it's also Saturday afternoonr!)

:eval => "detail.bookings.collect{ |booking| booking.date }.join(', ')"

Many thanks,

Jon.
