What are the differences between Rails MVC and MVP?

What are the differences between Rails MVC and MVP?

Rails MVC (Model-View-Controller) is a design pattern that separates an application into three interconnected components, while MVP (Model-View-Presenter) is a variation that emphasizes the role of the presenter in handling the logic and communication between the model and view.

Can you explain how data flow works in both patterns?

In MVC, the controller receives input, updates the model, and then updates the view. In MVP, the view interacts with the presenter, which updates the model and then updates the view, allowing for more testable and decoupled components.

Which pattern is better for web applications?

It depends on the specific needs of the application. MVC is widely used in web frameworks like Rails for its simplicity, while MVP can be beneficial for applications requiring more complex user interactions and testing.

Are there any performance differences between the two?

Performance can vary based on implementation, but generally, MVC may have a slight edge in web applications due to its direct data flow, while MVP might introduce some overhead due to the additional layer of the presenter.
