неопределенный метод `ensure_initialized» рельсы

Question

У меня есть composite_primary_keys камень установить и использовать с Rails 4.2.0.rc2, и я получаю ошибку

undefined method `ensure_initialized' for #<ActiveRecord::AttributeSet:0x007fcb319ed988> 

из этого line:

Array(self.class.primary_key).each {|key| @attributes.ensure_initialized(key)} 

Stack:

Это вызвано bug в версии, которую вы используются для драгоценного камня. обновить драгоценный камень:

bundle update composite_primary_keys 

и повторите попытку.
