* ActiveRecordのカラム値を簡単に正規化する仕組み

#+BEGIN_SRC ruby

class Book < ActiveRecord::Base

  with_options(:hankaku => true, :strip => true) do |o|

    o.normalize :title, :strip_tags => true

    o.normalize :body, :enter => true

  end

end

article = Book.create!(:title => "Ｒａｉｌｓの本　")

article.title # => "Railsの本"

#+END_SRC
