What is the Rails controller layer?

Can you explain what the Rails controller layer is?

The Rails controller layer is responsible for handling incoming requests, processing them, and returning responses. It acts as an intermediary between the model and the view.

How does it interact with models and views?

Controllers receive user input, interact with models to retrieve or manipulate data, and then pass that data to views for rendering.

Can you give me an example of a controller action?

Sure! A typical controller action might be def show, which retrieves a specific record from the database and displays it in a view.

What are some best practices for writing controllers in Rails?

Some best practices include keeping actions concise, using strong parameters for security, and following RESTful conventions.
