## What it is
A Ruby gem that lets any Ruby object behave like an ActiveRecord model, with attributes, validations, and callbacks, without requiring a database table. It supports form/presenter models and extending existing ActiveRecord records with model-specific behavior.

## Use cases
- create form models not backed by a database table
- add sign-up-only validations and callbacks to a user model
- build presenter models in Rails with ActiveRecord amenities
- define virtual attributes with defaults on plain Ruby objects
- keep controller-specific logic out of shared ActiveRecord models

## When to choose
- you need ActiveRecord-like validations and callbacks on non-database-backed models
- you want per-form behavior on top of existing ActiveRecord records
- you need lazy or instance-context attribute defaults beyond Rails' built-in .attribute

## When to avoid
- you only need simple virtual attributes available in vanilla Rails 5+
- your project does not use ActiveRecord or Rails
- you need to override existing database-backed column behavior

## Facets
- artifact type: library
- maturity: active
- function: orm, form-handling
- domain: web-development, backend, developer-tools
- platform: ruby
- tags: activerecord, rails, form-models, virtual-attributes, presenters, web-server
