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:index
class Address
include Virtus.model
attribute :name
attribute :city
end
class Invoice < ApplicationRecord
include DocumentSerializable
attribute address, Address
attribute subject
end
Then 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 run the tests. You can also run bin/console
for an interactive prompt that will allow you to experiment.
