Usage

In your migrations you can define integer fields such as:

class CreateUsersTable < ActiveRecord::Migration
  def self.change
    create_table :users, force: true do |t|
      t.string  :name, null: false
      t.integer :age,  null: false, unsigned: true
    end
  end
end

You can redefine in the existing fields.

class ChangeColumnToUsersTable < ActiveRecord::Migration
  def self.change
    change_column :users, :age, :integer, null: false, unsigned: false
  end
end

And you can also redefine in the primary key.

class ChangeColumnToUsersTable < ActiveRecord::Migration
  def self.change
    change_column :users, :id, :integer, null: false, auto_increment: true, unsigned: true
  end
end
