DocumentSerializable

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 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.
