How to disable auto-increment in primary key

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

Given that it looks to me like you want to implement uuid fields in your
application maybe this will help:
