The video starts by explaining the need for update functionality. It then details the creation of a GET endpoint for editing clubs, using `/clubs/{clubId}/edit`. This involves a `Path variable` to capture the club ID and a `ClubService.findClubById` method to retrieve the club's data. The process includes generating the `findClubById` method and mapping the entity to a DTO for display.
The next step focuses on creating the `edit.html` template. This involves copying the existing `create.html` and modifying it. Key changes include updating the form's `th:action` to reflect the edit endpoint, incorporating the club ID into the URL, and adding a hidden input field for the club ID to ensure it's passed during the update.
This section covers the implementation of the POST endpoint for updating club data. It uses `/clubs/{clubId}/edit` and takes both the club ID (from the path variable) and a `ClubDto` (from the model attribute). The tutorial emphasizes setting the club ID in the DTO before calling `ClubService.updateClub`. It also details the creation of the `updateClub` method in the service layer, which involves mapping the DTO back to a club entity and saving it to the repository.
The video demonstrates how to add an 'Edit' button to each club listing on the `clubs.html` page. This button uses `th:href` to navigate to the edit page for the specific club, dynamically including the club's ID in the URL. A quick test shows the update functionality in action, highlighting the need for validation in future updates due to uncontrolled input.
