Tableless model in rails 3.1

Question

Looks like this method doesn't work anymore in rails 3.1. So, does someone have a working solution?

Actually, I've found this gist. It solves problems with columns_hash and column_defaults errors from the railscast's solution but I get ActiveRecord::ConnectionNotEstablished error all the time when I try to write some attribute.

Any thoughts?

You should create your own model class and mix in the parts of ActiveModel (for example, validations) that you require. This blog post from Yehuda Katz has the details.
