NormalizerJp

This gem a provites a simple and flexible way to normalize attributes of Ruby Object. NormalizerJP includes a word JP(stands for Japanese), but this gem is useful for the other(not Japanese) because you can use your customized Normalizer.

Add this line to your application's Gemfile:

gem 'normalizer_jp'

Or install it yourself as:

$ gem install normalizer_jp

Start off by generating normalizer:

bin/rails g normalizer Strip

this should give you a file in:

app/normalizers/strip_normalizer.rb

Check out this file for some hints on how you can customize your normlizer. It should look something like this:

class StripNormalizer < NormalizerJp::Normalizers::Base
  class << self
    # Normalizer class's responsibility is implimentaion of call method as class method
    def call(attribute_value)
      # Here's normalizer space
    end
  end
end

you can use normalizers of this gem.

class User < ActiveRecord
  include NormalizerJp::Normalizers

  mount_normalizer :name_kana, HiraganaNormalizer
end

normlizer works as following:

user = User.new
user.name_kana = 'イトウアサコ'
user.name_kana #=> 'いとうあさこ'

you can use custom normalizers. custom normalizers's responsibility is implementation of call method as class method. It's super cool.

# app/normalizers/upcase_normalizer.rb
class UpcaseNormalizer < NormalizerJp::Normalizers::Base
  class << self
    def call(attribute_value)
      attribute_value.to_s.upcase
    end
  end
end

# app/models/blog.rb
class Blog < ActiveRecord
  mount_normalizer :title, UpcaseNormalizer
end

custom normalizer works as following:

blog = Blog.new
blog.title = 'awesome title'
blog.title #=> 'AWESOME TITLE'
