In Agile, the authors explain that when a user navigates to localhost:3000/say/hello, rails matches the route pattern. It is Restful, I think. Rails reads say as a controller and hello as one of the actions listed in the controller.
It creates a new instance of the Ruby class SayController
It creates a new object holding the current time and puts it into the instance variable @time.
It looks for a template (i.e. a view… view = template and template = view) to display the variable
In Rails one calls methods that help make the view/template easier „helpers“.
In Rails one calls methods in the Controller handling RESTful requests „actions.“
In Rails one calls RESTful POST requests „create“ actions in the controller.
