Nilify

Nilify is an ActiveRecord Plugin that allows you to easily convert default values to nil. Only attributes you specify will be checked and converted.

Default values are:

  String:   ""
  Numeric:  0
  Time:     1970-01-01 00:00:00

Installation

  script/plugin install git://github.com/grobie/nilify.git

Example

  class User < ActiveRecord::Base
    nilify :name, :salary, :birthday
  end

  user = User.create(:name => "", :salary => 0, :birthday => Time.parse("1970-01-01"))
  user.name       # => nil
  user.salary     # => nil
  user.birthday   # => nil
