Serialize your object hierarchy in a document based style to your relational database via virtus.
Add this line to your application's Gemfile:
gem 'document_serializable'And then execute:
$ bundle
Or install it yourself as:
$ gem install document_serializable
Define your model:
rails g model Invoice properties:jsonb:indexclass Address
  include Virtus.model
  attribute :name
  attribute :city
end
class Invoice < ApplicationRecord
  include DocumentSerializable	
  attribute address, Address
  attribute subject
endThen initialize it with content and access attributes directly from your model:
invoice = Invoice.new subject: "Pay me!", address: { name: "Jon Doe", city: "New York" }
invoice.address.name # Jon Doe
invoice.subject # Pay me!
invoice.save!This works for all models that have a serialized attribute named properties (e.g. json column in MySQL or jsonb in Postgres).
You can also query for properties (in Postgres):
Invoice.where("properties @> ?", { address: { city: "New York" } }.to_json)After checking out the repo, run bin/setup to install dependencies. Then, run rake spec to run the tests. You can also run bin/console for an interactive prompt that will allow you to experiment.
To install this gem onto your local machine, run bundle exec rake install. To release a new version, update the version number in version.rb, and then run bundle exec rake release, which will create a git tag for the version, push git commits and tags, and push the .gem file to rubygems.org.
