How to turn off auto_increment in Rails Active Record

Question

Is it possible to create primary key without auto_increment flag in ActiveRecord?

I can\'t do

create table :blah, :id          


        

Answer 1

In Rails 5 you can do

create_table :blah, id: :integer do |t|

If you want to change the name of primary key column pass primary_key parameter:

create_table :blah, id: :integer, primary_key: :my_awesome_id do |t|

See create_table documentation.
