Answer 1

Я зафиксировал проблему, один из названия ассоциации была связь моего приложения, которое зарезервированное слово в активной записи драгоценного камня:

См линия # 135 https://github.com/rails/rails/blob/3-2-stable/activerecord/lib/active_record/persistence.rb

Я изменил ассоциацию имя от подключения к чему-то еще, и теперь все в порядке.
