1. Request with the URL

4. The application determines the requested controller and action with the help of an application component named urlManager.
5. The application creates an instance of the requested controller to further handle the user request. The controller determines that the action show refers to a method named actionShow in the controller class.
6. The action reads a Post model whose ID is 1 from the database.
7. The action renders a view named show with the Post model.
8. The view reads and displays the attributes of the Post model.
9. The view executes some widgets, embed the rendering result in a layout and displays it to the user.
