# Learnings — edit-page-restructure
## 2026-03-29 — Session start
### Code Conventions
- Migrations: anonymous class `return new class extends Migration {`; methods `up(): void`, `down(): void`
- Models: `$fillable` array; `casts()` method (not `$casts` property); promoted properties in constructor
- SoftDeletes: used on Song and Slide models; `whereNull('deleted_at')` in manual queries
- PHP string concat: no spaces around `.` operator
- Return types always present; union types for multiple returns
- Relationships: typed return types (`HasMany`, `BelongsTo`)
- Error messages: German Du-form; flash `->with('success', '...')`; JSON `'message'` key
### Codebase Facts
- `service_songs` table stores ONLY songs from CTS agenda (via `getSongs()`)
- `EventAgendaItem.type` actual values: UNKNOWN — Task 5 will discover
- `EventAgendaItem.getItems()` returns ALL agenda items (not just songs)
- `isBeforeEvent=true` items should be excluded from visible agenda
- Settings stored as plain strings in `settings` table (key-value)
- Settings controller uses `MACRO_KEYS` constant array for validation
- SlideUploader sends `type`, `service_id`, `expire_date` in FormData
- PlaylistExportService builds: info slides → matched songs → moderation → sermon (OLD ORDER)
- Backward compat needed: old services without agenda items fall back to block-based export
### Test Patterns
- Pest v4 function-style: `test('description', function() { ... })`
- DB reset: `use RefreshDatabase;` in class-based, or implicit in Pest
- Inertia assertions: `$response->assertInertia(fn ($page) => $page->component('...')->has('...'))`
- Mocked API: injectable closures in ChurchToolsService constructor
- Storage: `Storage::fake('public')` in beforeEach for file tests
- Carbon: `Carbon::setTestNow(...)` for deterministic dates
## 2026-03-29 — ServiceAgendaItem DB schema
### Created
- Migration: `2026_03_29_100001_create_service_agenda_items_table.php` — contains all EventAgendaItem fields from CTS
- Migration: `2026_03_29_100002_add_service_agenda_item_id_to_slides_table.php` — links slides to agenda items
- Model: `ServiceAgendaItem` with `scopeVisible()`, relationships (service, serviceSong, slides)
- Factory: `ServiceAgendaItemFactory` with `withSong()` and `nonSong()` states
- Tests: `ServiceAgendaItemTest` — 14 tests covering schema, relationships, cascades, scopes
### Key Fields
- `cts_agenda_item_id` (nullable, indexed): CTS API item ID for syncing
- `position` (string): CTS agenda item position (e.g. "1", "2", "1.1")
- `type` (string): CTS type value ("Song", "Default", "Header", etc.)
- `is_before_event` (boolean): filters with `scopeVisible()` scope
- `responsible` (json → array cast): responsible persons
- `service_song_id` (nullable FK): links agenda item to song (nullOnDelete)
- `sort_order` (unsignedInt): unique per service with `unique(['service_id', 'sort_order'])`
### Relationships
- `service()` BelongsTo Service (cascadeOnDelete)
- `serviceSong()` BelongsTo ServiceSong (nullable, nullOnDelete)
- `slides()` HasMany Slide (new FK added to slides table)
### Test Patterns
- Factory states: `->withSong(song)` for song items, `->nonSong()` for non-song
- Scope: `ServiceAgendaItem::visible()` filters `is_before_event=false`
- Migrations now always use anonymous class `return new class extends Migration {}`
- Unique constraint throws `QueryException` when violated (tested)
### Slide Model Update
- Added `service_agenda_item_id` to fillable
- Added `serviceAgendaItem()` BelongsTo relationship (nullOnDelete)
## 2026-03-29 — AgendaMatcherService
### Implementation
- Created `AgendaMatcherService` with 4 public methods for glob-style wildcard matching
- Uses PHP's native `fnmatch($pattern, $title, FNM_CASEFOLD)` for * wildcard support and case-insensitive matching
- Key methods:
- `matches(string $itemTitle, string $pattern): bool` — single pattern match
- `matchesAny(string $itemTitle, array $patterns): bool` — match against array
- `findFirstMatch(array $agendaItems, string $patterns): ?ServiceAgendaItem` — comma-separated patterns, returns first match or null
- `filterBetween(array $items, ?string $startPattern, ?string $endPattern): array` — filters items between boundaries (boundaries excluded)
### Test Coverage
- 17 tests in Pest function-style covering all methods
- Patterns tested: exact match, suffix wildcard, prefix wildcard, both sides, case-insensitive, no-match
- `filterBetween` edge cases: both boundaries, start-only, neither, no-matching-start, empty arrays
- Pattern parsing: comma-separated patterns with whitespace trimming
- All tests pass; Pint clean
### Code Patterns
- Service class structure matches `SongMatchingService` (constructor, public methods, no state)
- Public method documentation via docstrings (necessary for API clarity)
- Test organization via section headers (necessary for readability)
- No regex used — just `fnmatch()` for simplicity and correctness
## 2026-03-29 — Settings Controller Agenda Keys
### Added 4 New Configuration Keys
- `agenda_start_title` — start boundary title pattern for agenda display
- `agenda_end_title` — end boundary title pattern
- `agenda_announcement_position` — comma-separated patterns for announcement position
- `agenda_sermon_matching` — comma-separated patterns for sermon recognition
### SettingsController Updates
- Modified `MACRO_KEYS` constant array in `SettingsController.php` to include the 4 new keys
- Validation automatically accepts new keys via `'in:'.implode(',', self::MACRO_KEYS)` rule
- `index()` already iterates through all MACRO_KEYS, so no additional logic needed
- Settings fetched via `Setting::get($key)` and passed to Inertia
### Test Implementation
- Created `tests/Feature/SettingsControllerAgendaKeysTest.php` with 6 Pest tests
- Test patterns used:
- `$response->assertInertia()` with `->has('settings.key')` for prop assertions
- `$this->patchJson(route('settings.update'), [...])` for PATCH requests
- `Setting::get($key)` to verify database persistence
- `$response->assertUnprocessable()` for invalid key validation
- All tests pass; code passes Pint formatting
## 2026-03-29 — DiscoverAgendaTypes command
### Implementation
- Created `DiscoverAgendaTypes.php` artisan command (cts:discover-agenda-types)
- Fetches next upcoming service from DB (date >= today, order by date ASC)
- Calls `ChurchToolsService->syncAgenda($ctsEventId)` to fetch agenda
- Displays formatted table: Position | Titel | Typ | Hat Song | Vor Event | Dauer
- Prints distinct type values found in agenda items
### Key Methods Used
- `$agenda->getItems()` returns array of EventAgendaItem
- `EventAgendaItem` getters: `getPosition()`, `getTitle()`, `getType()`, `getSong()`, `getIsBeforeEvent()`, `getDuration()`
- `Str::limit($string, 40, '...')` truncates titles to 40 chars
### Test Coverage (5 tests)
- No service found → outputs "Kein bevorstehender Service gefunden."
- Displays table and unique types from agenda items
- Handles null agenda → outputs "Keine Agenda für diesen Service gefunden."
- Handles empty items array → outputs "Keine Agenda-Items gefunden."
- Truncates long titles (40 chars) and still displays unique types
### Code Patterns
- Command signature: `protected $signature = 'cts:discover-agenda-types';`
- Dependency injection via `handle(ChurchToolsService $churchToolsService): int`
- Test mocking: `$this->app->bind(ChurchToolsService::class, function () use (...) { ... })`
- Table output: `$this->table($headers, $rows)` with array of arrays
- Info output: `$this->info()` for text, `$this->line()` for list items
### Status
- ✓ Command created: `app/Console/Commands/DiscoverAgendaTypes.php`
- ✓ Tests created: `tests/Feature/DiscoverAgendaTypesTest.php` (5 tests, all passing)
- ✓ Pint formatting: clean (`pint --test` passes)
- ✓ Ready for: `git commit -m "chore(debug): add CTS agenda type discovery command"`
## 2026-03-29 — Service::finalizationStatus() refactor
### Implementation
- Updated `Service::finalizationStatus()` to check new `service_agenda_items` model
- Added backward compatibility: if `agendaItems()->count() === 0`, fall back to legacy `finalizationStatusLegacy()`
- New checks (agenda-based):
1. Unmatched songs: Find agenda items with `service_song_id` where `serviceSong.song_id IS NULL`
- Warning format: `"{songName} wurde noch nicht zugeordnet"`
2. Songs without arrangement: Find agenda items where `serviceSong.song_arrangement_id IS NULL`
- Warning format: `"{songName} hat kein Arrangement ausgewählt"`
3. Sermon slides:
- If `Setting::get('agenda_sermon_matching')` configured: check if any matching agenda item has slides
- Else: fall back to legacy check `$this->slides()->where('type', 'sermon')->exists()`
- Warning: `"Keine Predigt-Folien hochgeladen"`
### Code Changes
- Modified: `app/Models/Service.php`
- Added import: `use App\Services\AgendaMatcherService;`
- Updated `finalizationStatus()` method (95 lines)
- Added private `finalizationStatusLegacy()` method (28 lines) for backward compat
- Used `app(AgendaMatcherService::class)` to instantiate service for pattern matching
- Preserved `agendaItems()` HasMany relationship (added in earlier Task)
- Modified: `tests/Feature/FinalizationTest.php`
- Added imports: `ServiceAgendaItem`, `Setting`
- Renamed first test to `finalize ohne voraussetzungen gibt warnungen zurueck (legacy)` for clarity
- Added 6 new agenda-based tests:
1. `agenda finalization warnt bei unzugeordneten songs` — unmatched song warning
2. `agenda finalization warnt bei songs ohne arrangement` — no arrangement warning
3. `agenda finalization bereit wenn alle songs zugeordnet und arrangement` — all pass
4. `agenda finalization warnt wenn keine predigtfolien und sermon setting konfiguriert` — sermon with setting
5. `agenda finalization ok wenn predigtfolien bei sermon item vorhanden` — sermon slides exist
6. `agenda finalization warnt wenn keine predigtfolien und kein sermon setting` — no setting fallback
### Test Results
- All 18 tests pass (12 existing + 6 new)
- Backward compatibility verified: legacy tests with `service_songs` still work
- Pint formatting: clean
### Code Patterns Used
- Guard clause in `finalizationStatus()` for backward compat check
- `$agendaItems->filter()` with closures for conditional filtering
- Service instantiation via `app(AgendaMatcherService::class)` with closure captures
- Null-safe navigation: `$item->serviceSong?->song_id`
- Setting retrieval: `Setting::get('agenda_sermon_matching')`
- Slide filtering: `whereNull('deleted_at')` for soft deletes
