rails 3.0.12 how to check what version of activerecord do i have?
rails-activerecord, ruby-on-rails-3
Solution
Run `bundle show activerecord` at the terminal.
Problem
Maybe it's a silly question but I need multiple primary keys in some tables something like... ``` create table t1 ( id int not null id_something int not null . . . primary key (id, id_something) ) ``` I googled and I found this gem http://rubygems.org/gems/composite_primary_keys but I couldn't find what activerecord version do I have I'm using rails 3.0.12 and ruby 1.9.2p320
