primary_key (name, type = :primary_key, **options)

Defines the primary key field. Use of the native PostgreSQL UUID type is supported, and can be used by defining your tables as such:

create_table :stuffs, id: :uuid do |t|
  t.string :content
  t.timestamps
end

By default, this will use the gen_random_uuid() function.

To use a UUID primary key without any defaults, set the :default option to nil:

create_table :stuffs, id: false do |t|
  t.primary_key :id, :uuid, default: nil
  t.uuid :foo_id
  t.timestamps
end

You may also pass a custom stored procedure that returns a UUID or use a different UUID generation function from another library.

Note that setting the UUID primary key default value to nil will require you to assure that you always provide a UUID value before saving a record (as primary keys cannot be nil). This might be done via the SecureRandom.uuid method and a before_save callback, for instance.
