More specifically, you will combine Thymeleaf and Spring Boot with Spring Data and Spring Security. In a nutshell, this course will give you all the basics you need to start developing an application using Thymeleaf and Spring Boot.

Throughout the course, you will be building an application of a fictional basketball team called Thyme Wizards. Additionally, you will also learn to use unit and integration tests to ensure the proper code functionality and build a maintainable codebase that you can expand upon.

By the end, you will have a new project to add to your portfolio and some great new skills that employers will love.

Building Scalable Applications with Thymeleaf and Spring Boot

# The need for flash attributes
The delete works nicely, but the usability could be improved. The modal just closes without any
indication that the user was actually removed. It would be a lot better to show a message after the
redirect to the list of users. Something like "User Francine Connely was deleted."

# What are flash attributes?

Spring MVC has the concept of **flash** attributes. These attributes can be added in the controller's `POST` and will be made available in the `GET` method following the redirect we do at the end of the `@PostMapping` method.

`org.springframework.web.servlet.mvc.support.RedirectAttributes` interface into our controller method:

Explore the concept of flash attributes stored temporarily before a redirect and removed after they’ve been used.
