📝 Walkthrough

Walkthrough

The PR implements full-stack case management: JPA now auto-generates UUIDs for case IDs, the UI controller integrates with CaseService for CRUD operations, and templates transition from static placeholders to dynamic Thymeleaf rendering displaying actual case data. A shared head fragment consolidates common template structure and styling.

Changes

Cohort / File(s)	Summary
Persistence Layer src/main/java/.../infrastructure/persistence/CaseEntity.java	Added @GeneratedValue(strategy = GenerationType.UUID) annotation to the id field, enabling JPA to auto-generate UUID values instead of requiring external provision.
Controller Layer src/main/java/.../presentation/web/UiController.java	Integrated CaseService via constructor injection; updated /ui/cases GET to populate cases list, /ui/cases/new GET to initialize empty CaseDTO, added new POST handler to create cases, and modified /ui/cases/{caseId} GET to accept UUID and fetch actual case details.
View Templates (Case Pages) src/main/resources/templates/cases/detail.html, cases/list.html, cases/new.html	Replaced static placeholder content with dynamic Thymeleaf conditionals; detail template shows case fields or "not found" message, list template renders cases table or empty state, new template binds form to caseDTO model object.
Shared Template Fragment & Layout src/main/resources/templates/fragments/head.html, index.html	Created new shared head fragment with comprehensive inline CSS (theme, layout, typography, responsive grid); updated index.html to use fragment instead of inline meta/stylesheet tags.

Poem

🐰 Cases now bloom with auto-UUIDs bright,
Service layer guides each form through the night,
Templates dance with Thymeleaf's dynamic grace,
From static stubs to living, breathing space! ✨

`@src/main/java/org/example/projektarendehantering/presentation/web/UiController.java`:
- Around line 34-43: Replace direct binding of CaseDTO in UiController.newCase
and UiController.createCase with a new CreateCaseForm DTO that exposes only
title and description; update the GET to model.addAttribute("createCaseForm",
new CreateCaseForm()) and the POST to accept `@Valid`
`@ModelAttribute`("createCaseForm") CreateCaseForm form, then construct a new
CaseDTO inside createCase copying only title/description (do not accept
id/status/createdAt from the client) and pass that CaseDTO to
caseService.createCase(); also add CreateCaseForm with validation annotations
and update templates/cases/new.html th:object to use createCaseForm. Ensure
CaseMapper.toEntity and CaseService.createCase remain unchanged so only
server-generated fields are set server-side.

In `@src/main/resources/templates/fragments/head.html`:
- Around line 123-131: The CSS removes the keyboard focus indicator by using
"outline: none" on the .input selector; restore an accessible focus cue by
removing the global outline suppression and adding a visible focus style for
.input:focus (e.g., a high-contrast outline or box-shadow using your theme
variables like --focus or --border) so keyboard users get a clear, persistent
focus ring; update the .input rule and add a .input:focus rule (or
:focus-visible) to provide a clear, high-contrast indicator that matches your
design system.
- Around line 3-6: The head fragment uses ${title} but callers discard child
nodes so pages fall back to "Ärendehantering"; update every caller (index.html,
cases/list.html, cases/detail.html, cases/new.html) to pass the page title
explicitly via the fragment parameter (use the head fragment name "head" and
supply the title, e.g. th:replace="~{fragments/head :: head('Cases')}"), or
alternatively set a "title" model attribute in the corresponding UiController
handlers so ${title} is populated; ensure the fragment invocation and/or
controller model use the exact variable name "title" referenced in the head
fragment.
