The action reads a Post model whose id is 1 from the database.1. A user makes a request with the URL & the server handles it by executing the bootscrap script index.php3. The application obtains the detailed user request information from an application component named requet2. The bootscrap script creates an application instance and runs it4. The application determines the requested controller and action with the help of an application component named urlManager.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 (if available).10. The view rendering result is embedded in a layout.filters11.
