How can i disable the auto-increment for a primary key data type. The purpose of using primary_key data type is using different name for primary key. But we still want to use all the properties of "id" except for auto increment part.

I had my migration as following #=============MIGRATION def self.up     create_table :pk2s , :id=> false do |t|       t.primary_key :uid       t.string :name

      t.timestamps     end   end

# ========== Model class Pk2 < ActiveRecord::Base   set_primary_key "uid" end
