Archive 2s

This gem provides the ability to archive a meaningful bit of information. This is good for use with friendly_id or stats. It will save to a single table that is created via a migration copied from the rake task

Usage

archive_2s accepts two optional parameters, :method_name and :include_by_default

class Item < ActiveRecord::Base
  archive_2s :method_name => :name, :include_by_default => true

  def name
    [self.first_name, self.middle_initial, self.last_name].join(' ')
  end
end

:method_name is the methods return value you wish to save and :include_by_default will include archived results when you fetch by id only (as all that is saved is the id and a value of a method)

All objects returned are readonly.

Migration

See the last todo, this needs to me a generator/rake task but I am tired and want to goto sleep

create_table :archived_to_s do |t|
  t.datetime  :archived_at
  t.string    :model_type
  t.integer   :model_id
  t.string    :archived_value
end
add_index :archived_to_s, [:model_type,:model_id,:archived_at], :name => 'model_and_archive_date_idx', :unique => true

Todo

make some proxy magic so if one calls a relationship if can search the archive too
use wants rather then returning based on length
drop the id column and use the index for the model
make the doco usefull
make a generator for rails 2 and 3
