To extract view logic from Rails models using presenters, wrap your model with a SimpleDelegator-based class in an app/presenters hierarchy. This encapsulates formatting and display methods, keeping models slim and views expressive through clean separation of concerns.

The best way to organize Rails view formatting is using the Presenter pattern. You create dedicated presenter classes like ApplicationPresenter or UserPresenter to centralize formatting, enabling reusable UI components and nil-safe delegation across views and controllers.

Yes, the Rails presenter pattern works with RSpec tests. You write RSpec tests to verify formatting and display methods within your presenter objects, ensuring that the extracted presentation logic behaves correctly and remains maintainable.

Yes, you can use Rails helpers inside a presenter object. Presenters support integration with Rails helpers, allowing you to build reusable display components and compose complex displays while maintaining nil safety and clean delegation.

You should avoid using a presenter for view logic in Rails when your display requirements are minimal or purely static. Presenters are designed for extracting complex presentation concerns from models and building reusable UI components, so simple views may not need this layer.
