Rails and serialized nested DataObjects

I wanted to store arbitrary nested data structures in a jsonb column and be able to retrieve and work with that data seemlessly within a Rails application. There are several tutorials covering different aspects of this, but none felt complete to me.

For this example we'll be working with a User model that can define surveys. Each survey consists of n multiple choices questions, and each question can have between two and ten answer options.

Requirements:

In this case we use Postgresql's JSONB support to store the data, but you could also use other forms of serializing such as a text column and Rails' default YAML serializing. JSONB is chosen in this case because it leaves open the possiblity of querying the data with SQL. Also, apparently serializing to JSON is much faster.[1]

Pain Points in Rails

Rails has several pain-points for more complex web applicatoins that frameworks like Hanami and Trailblazer attempt to address. By addressing theses issues your business logic is better isolated from the framework details/implementation, clearer responsibilities, easier reasoning about, cleaner code, creates opportunity for easy further abstraction when necessary, allows for simpler testing, etc.

Identified Pain Points and potential solutions

Better file structure/autoloading that allows grouping of domain concerns under a single folder structure

Solutions: use custom autoload_paths/eager_load_paths in an initializer?

# config/application.rb
config.autoload_paths = Dir['app/domains/*/*/']

// Handles ordering elements on the page using
// buttons than can move the elements up or down.
//
// Usage:
// 1. Add data-controller orderable on a parent node.
// 2. (Optional) For persisting order to input fields:
//    - add data-orderable-target="orderInput"
// 3. Wire up buttons or links to call up/down actions.
