Hstorable

This gem simplifies working wih fields stored using Hstore

How to use

To use hstorable you should add this line to your Gemfile:

gem 'hstorable', '~> 0.0.5'

Note, this gem depends on hsore extension of PostgreSQL. So, you should create this extension in your db:

CREATE EXTENSION hstore;

It is pertty easy to use HStorable with STI in RoR. First of all you shoud create table like this:

create_table :wrappers do |t|
  t.hstore :properties, default: '', null: false
  t.string :type, null: false
  t.timestamps
end

That's all. Now you can use hstorable to solve your problems.

class Api::Wrapper < ActiveRecord::Base
  include Hstorable
end

class Api::OneApiWrapper < Api::Wrapper
  hstore_simple :properties, name: 'consumer_key'
  hstore_simple :properties, name: 'consumer_secret'
  hstore_simple :properties, name: 'api_version', default: '26.0'
  hstore_simple :properties, name: 'code', readonly: true
  hstore_simple :properties, name: 'access_token', readonly: true
  hstore_simple :properties, name: 'refresh_token', readonly: true
  hstore_simple :properties, name: 'instance_url', readonly: true
  hstore_simple :properties, name: 'state', readonly: true, default: 'created'
end

class Api::AnotherApiWrapper < Api::BaseWrapper
  hstore_simple :properties, name: 'user_name'
  hstore_simple :properties, name: 'secret'
end

Different types of models with different set of fields will be stored in one table. And you can use it as ordinary model's properties.

api = Api::OneApiWrapper.new(consumer_key: '743b57c3120b49b42588011066411d98', cosumer_secret: '743b57c3120b49b42588011066411d98')
api.cosumer_key # => '743b57c3120b49b42588011066411d98'
api.cosumer_secret # => '743b57c3120b49b42588011066411d98'
api.save
api.update cosumer_key: '2afc9269f7ceb78533d6a2e2d72a14f9'

Cool, isn't?
