StoreModel is a Ruby gem that allows you to wrap JSON columns in ActiveRecord models, providing type safety, validations, and familiar ActiveModel behavior.

When should I use this skill instead of standard store_accessor?

Use this skill when your JSON data requires complex validations, specific data types (like integers or booleans), or nested structures that store_accessor cannot easily handle.

Does it support database-level queries?

While StoreModel handles the object-oriented side, you still use standard PostgreSQL JSONB operators for database-level querying, or use this skill to map those structures.

Can I use this for arrays of objects?

Yes, the skill includes patterns for to_array_type, allowing you to manage collections of nested objects within a single JSON column with full validation.

Database Management

Wraps JSON-backed database columns in ActiveModel-like classes for type safety, validations, and structured data management in Ruby on Rails.

This skill automates the implementation of the store_model gem within Ruby on Rails applications, allowing developers to treat JSONB columns as structured, validated objects. It provides standardized patterns for defining attributes, enums, and nested models, making it ideal for complex configuration objects or document-style data stored within a relational database. By bridging the gap between schemaless JSON and structured ActiveRecord models, it ensures data integrity and clean code separation while maintaining the flexibility of NoSQL-style storage.

Key Features

01Define type-safe attributes for JSON and JSONB columns

02Implement standard ActiveModel validations on nested JSON data

03Support for Rails-style enums within JSON-backed fields

04Handle complex nested structures and arrays of models with ease

05Generate production-ready controller patterns and RSpec tests
