Virtualize

Virtualize allows ActiveRecord to have virtual attributes.

Super simple substitute for such as redis-objects

Installation

Add this line to your application's Gemfile:

gem 'virtualize'

And then execute:

$ bundle

Or install it yourself as:

$ gem install virtualize

Usage

Basic:

class Blog < ActiveRecord::Base
  include Virtualize

  set_virtual_attributes :memo, on: :virtual
end

you MUST add the column named virtual with type TEXT.

@blog = Blog.last
@blog.memo #=> nil
@blog.memo = 'hoge'
@blog.save
@blog.memo #=> 'hoge'

Use standard save or save! methods for persistence.

The form helper and mass assignment are also supported.

= form_for @blog do |f|
  = f.text_area :memo

@blog = Blog.find(params[:id])
@blog.update_attributes!(params[:blog].permit!)

Caution

You should not use this function for a lot. This is only for the misc columns.

You should think another way for storing altenate key or the column using for search or order.
