Missing database in RadRails

They took the screencast that shows you how to do this off their site.
Luck for you, I have a copy. Reply with your email address and I'll
send you the screencast, so long as you can accept 8-9 Mb attachments.

Also it does not sound like your new site has its database.yml file set
up right. I was just running into the same exact:
Errno::EBADF -- Bad file descripto - connect(2)

If you do a search in this group for that error you will find how I
handled it.

Here you go. I just threw it up on a web server.
