Rails 3 and Force.com Toolkit for Ruby?

I am interested in working with Salesforce data from a Rails 3 app. I've done some experiments with asf-rest-adapter but it doesn't seem like I can use models with it, which i would like to do. Does anyone know if force.com toolkit for ruby works with rails 3? Did I misunderstand asf-rest-adapter? Is there some other solution that anyone recommends?
