Its occasionally necessary to work with Active Record style models (See: Gems that rely heavily on AR) You can circumvent getting messy with your models by scoping them and using the AR::Lint test
Quick and Dirty version:
change your class definition as follows:
class Rockies < ActiveRecord::Base #Model Code end
to mimic the following
class Rockies include ActiveModel::Validations include ActiveModel::Conversion extend ActiveModel::Naming def persisted? false end #Model Code end
Thats pretty much it, If your models were generated using scaffolding this will unlink your model from the database and uses the ActiveModel LINT guide for best uses, its pretty stripped down so if you find a method you need thats not implemented by default, give the official LINT file a glance and see what classes you should include/extend.
