Generator fails for STI models
https://github.com/zeisler/active_mocker/issues/10

Using gems parser and unparser I am able to check the parent class and if it’s not ActiveRecord::Base load that class. Also when the parent class is ActiveRecord::Base I can change the source to ActiveMocker::ActiveRecord::Base.
