This document shows how to view single data records in Symfony 4. It includes Twig templates for displaying a list of records and a single record, as well as a DataController class with actions for getting a single record by ID from the database and passing it to the Twig template for display. The list template loops through records and links to the show action. The show template displays the fields of a single record passed from the controller.
