ActiveModel

ActiveModel is a component in the Ruby on Rails framework that provides a way to create objects that behave like database models without requiring a traditional database. It offers features such as attribute management, validations, and conversions, enabling developers to build form objects, value objects, or service objects with familiar model-like behavior. Essentially, ActiveModel helps structure data and enforce rules consistently, making it easier to implement complex logic while maintaining a clean and modular codebase, even when no database is involved.
