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/20...
