The empty error callback in loadMeteringData() silently swallowed API
failures, causing the chart to show 'Keine Daten' instead of the actual
error. Added proper error logging and user-facing error message.
Also added DashboardServiceTest for getMeteringDataOverview with
scenarios for data, no metering points, empty time range, and
multiple metering points.
The consumption dashboard sent dates like '2026-06-24T00:00:00' without
timezone offset, which Spring could not parse into java.time.Instant.
Append 'Z' suffix to produce valid ISO-8601 UTC timestamps.
Add section-based grouping to the sidebar navigation with headers and
dividers. Menu items are now organized into 4 sections:
- Allgemein (Übersicht, Zählpunkte, Mein Profil)
- Community (Community beitreten, Meine Mitgliedschaften, Verbrauch)
- Tarife & Einladungen (Meine Tarife, Einladungen)
- Verwaltung (Admin-only: Mitgliedschaften, Benutzerverwaltung, etc.)
Only sections with visible items for the current role are rendered.
All 107 frontend tests passing.
Switch interval_start/interval_end from LocalDateTime to Instant across the
entire metering data stack (entity, DTOs, parser, repository, services, controllers).
This eliminates DST-related unique constraint violations that occurred when two
different wall-clock times mapped to the same epoch millis during CET/CEST transitions.
Key changes:
- MeteringData entity: intervalStart/intervalEnd now Instant
- XlsxMeteringDataParser: produces Instant via JVM timezone conversion
- MeteringDataRepository: all queries use Instant parameters
- MeteringDataService: simplified deduplicate() (Instant has no DST ambiguity)
- Added hibernate.jdbc.time_zone=UTC and test profile for in-memory H2
- Added MeteringDataUploadIntegrationTest with real H2 database
- Added DST-specific parser and service tests
- All 216 tests passing
- Add TariffInviteServiceTest, GlobalExceptionHandlerTest, setup-test.ts
- Add compose plans/specs docs
- Extend .gitignore with *.xlsx, *.ps1, *.http, *.py, *.docx
- Remove stale test data files and scripts from working tree
- TariffService: extract ValidatedUserTariffPoints record from validateUserTariffRequest to eliminate redundant MeteringPoint loads in createUserTariff/updateUserTariff (saves 2 SELECT queries per create call)
- TariffService: move source != target check into validateUserTariffRequest for single-responsibility
- MeteringPoint: restrict CascadeType from ALL to PERSIST/MERGE and remove orphanRemoval to prevent accidental cascade deletes of independent Memberships
- MeteringPointService, MembershipService, MeteringDataService, TariffInviteService, TariffService: replace FQ org.springframework.security.access.AccessDeniedException with imported short form for consistency
The generated API service requires userId as a second parameter for
deleteUserTariff(). Inject AuthService and use getCurrentUserId() to
provide the required argument, unblocking the entire frontend test suite.
- Add vitest.config.ts for Angular 21 @angular/build:unit-test runner
- Install @angular/platform-browser-dynamic for TestBed initialization
- Regenerate API client from OpenAPI spec (npm run generate-api)
- Fix spec: use includes() for URL matching (generated API prepends basePath)
- Fix spec: 'should not reload' test assertion (0 not 1) for no-reload behavior
- All 107 frontend tests now pass (17 test files)
Add comprehensive tests covering:
- Tab navigation (pending/all) with signal verification
- loadAllUsers() calls correct endpoint via generated AdminIAMService

- Duplicate Status column header bug fix verification
- No reload of allUsers if already loaded
Add onCreate() method with @PrePersist annotation that sets createdAt
to LocalDateTime.now() on first persist, consistent with other entities
(UserTariff, CommunityTariff, etc.). Guard prevents overwriting existing
values. Two new tests verify auto-population and idempotency.
- Add three tabs: Ausstehende Anträge / Aktive Mitgliedschaften / Alle
- Card view for pending tab (existing approve/reject behavior preserved)
- Table view for active and all tabs (Name, Email, Community, Zählpunkt, Priorität, Status)

- getStatusBadgeClass() for color-coded status badges
- Client-side filtering for instant tab switching
- Add comprehensive tests (19 test cases)
- Add getAllUsers() to AdminIAMService (fixes compilation for admin-user-approval)
- Fix deleteUserTariff missing userId argument in user-tariff component
- Add activeTab signal ('pending' | 'all') with tab navigation UI
- Add allUsers signal with loadAllUsers() using generated AdminIAMService.getAllUsers()
- Add getStatusLabel() helper for German status labels (Ausstehend/Aktiv/Freigeschaltet/Inaktiv/Abgelehnt)
- Add getStatusBadgeClass() for color-coded status badges (yellow/green/red)
- Fix duplicate 'Status' column header bug in pending users table
- All-users tab shows Name, Email, Status badge, Rolle columns (no action buttons)
- Add 22 passing tests covering signals, helpers, tab switching, approve/reject, and template
Add method to fetch all admin memberships via GET /api/community/admin/memberships
with corresponding unit tests using Angular HttpClientTestingModule.
- Add getAllMemberships_returnsAllStatuses: verifies PENDING, ACTIVE, INACTIVE
- Add getAllMemberships_collectsDistinctUserIds: verifies distinct user ID collection
- Add getAllUsers_returnsSortedByCreatedAtDesc: verifies sorting order
- Add getAllUsers_returnsEmptyList: edge case for empty user list
- Add getAllUsers_includesAllRegistrationStatuses: verifies all statuses present
- All 172 backend tests pass
Add method to retrieve all users ordered by creation date descending.
This supports the admin user management overview feature.
Tests:
- UserRepositoryTest: verify method exists and returns List<User>
Add @Transactional(readOnly = true) method that uses findAllWithDetails()
and batch-fetches users with the same lookup pattern as getPendingMemberships().
Returns List<PendingMembershipResponse> with all memberships (pending, active,
inactive) for the admin overview tab.
Tests: 3 new tests covering normal case, empty list, and missing user.
- Add createdAt LocalDateTime field with @Column(updatable = false)
- No @GeneratedValue - set manually during user creation
- Set createdAt in AuthService.register() and AdminDataInitializer
- Ignore createdAt in UserMapper (mapped manually, not from DTO)
- Add UserTest with 3 tests verifying field, annotation, and default
Add @Query with JOIN FETCH on meteringPoint and energyCommunity, no WHERE clause
to return all memberships regardless of status. Includes reflection-based unit test
verifying method existence and annotation correctness.

date range picker, quick-range buttons (7/30/90 days)

line (community feed-in), tooltip with coverage percentage
- Summary cards: total consumption, coverage %, feed-in, covered kWh
- Warning when user has no community membership
- Route /dashboard/consumption (MEMBER only)
