You'll probably get better responses from the sequel list:

http://groups.google.com/group/s...

However, I'm not exactly sure why you define a create method when it is already
provided for you through Sequel::Model.

w = Website.new(:domain => 'somedomain.com')

This will generate an exception if somedomain.com already exists. If you just
want that model, whether it has been created previously or not,

w = Website.find_or_create(:name => 'somedomain.com')

The methods relating to this you are probably looking for are here:

Hope that helps.
