Recently, I've been working on a Rails project for the first time.
It's a nice change after years of perl.
There are quite a few little things that I knew how to do in perl, that I didn't have clue on how to do it in Rails. Also I run into issue peculiar to Rails or ruby.
I solved all these issues so far and the links below give pointers to some helpful information.
