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
