Rails Migration: How to increase column data type size by using ROR migration

Question

My users table login column is String type with limit of 40 characters. Now I am planning to increase the limit to 55 characters.

Any one please let me know how can we increase this limit by using ROR migration.

Thanks, Sravan

  def up
    change_column :users, :login, :string, :limit => 55
  end

  def down
    change_column :users, :login, :string, :limit => 40
  end
end
