This can be done by using the :id => false option: create_table :users, :id => false do |t| However, I would highly recommend against doing this. With a few exceptions. The primary one being join tables that use a compound primary key composed of two foreign keys. One important aspect of an ORM system like ActiveRecord is to have clear object identity. I do everything I can to avoid using natural primary keys, and I have VERY strong opinions about tables laking a primary key. For a comprehensive overview that lines up nicely with my opinions here is a well written article: http://rapidapplicationdevelopment.blogspot.com/2007/08/in-case-youre-new-to-series-ive.html -- Posted via http://www.ruby-forum.com/. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
