# 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

## 2026-03-29 — ServiceController::edit() agenda items

### Implementation
- Updated `ServiceController::edit()` to pass `agendaItems` and `agendaSettings` props to Inertia
- Added `agendaItems()` HasMany relationship to `Service` model
- Fixed pre-existing syntax error (duplicate code block) in `Service::finalizationStatus()`
- Added `use App\Services\AgendaMatcherService;` import to `Service` model (was missing)

### Controller Changes
- Added imports: `Setting`, `AgendaMatcherService`
- Extended eager loading to include `agendaItems` with nested relationships (slides, serviceSong.song.groups.slides, arrangements)
- Loads 4 agenda settings from DB: `agenda_start_title`, `agenda_end_title`, `agenda_announcement_position`, `agenda_sermon_matching`
- Filters out `is_before_event` items, applies `filterBetween()` with start/end boundaries
- Maps computed flags: `is_announcement_position` and `is_sermon` via `matchesAny()`
- Passes `agendaItems` (array of arrays) and `agendaSettings` (assoc array) alongside existing props

### Test Coverage (5 new tests)
1. `edit_seite_liefert_leere_agenda_items_und_settings` — empty agenda, null settings
2. `edit_seite_liefert_agenda_items_mit_computed_flags` — announcement/sermon flags
3. `edit_seite_filtert_agenda_items_mit_start_end_grenzen` — boundary filtering
4. `edit_seite_schliesst_before_event_items_aus` — is_before_event exclusion
5. `edit_seite_liefert_agenda_settings_mit_allen_vier_keys` — settings with values

### Pre-existing Issue Found
- `test_service_edit_seite_zeigt_service_mit_songs_und_slides` was already failing before changes (informationSlides size 0 vs expected 1) — factory generates random `uploaded_at` that can cause filtering issues

## 2026-03-29 — PlaylistExportService agenda-ordered export

### Implementation
- Refactored `generatePlaylist()` to check for `ServiceAgendaItem` records first
- Empty agenda → falls back to `generatePlaylistLegacy()` (old block-based order: info → songs → moderation → sermon)
- Agenda present → iterates items in `sort_order`, exporting songs and slides per item
- Information slides (announcements) inserted at `Setting::get('agenda_announcement_position')` pattern match, or prepended as fallback
- New `addSlidesFromCollection()` private method extracts common slide→.pro conversion logic
- Legacy `addSlidePresentation()` now delegates to `addSlidesFromCollection()` after querying

### Key Design Decisions
- `generatePlaylistLegacy()` is an exact copy of the original `generatePlaylist()` body — backward compat guaranteed
- Agenda items with `is_before_event=true` are excluded from export (matches display behavior)
- Song items without `song_id` (unmatched) count as skipped
- Non-song agenda items without slides are silently skipped
- `ProExportService` instantiated via `new` (not DI) — matches legacy pattern

### Test Coverage (8 new tests, all with `@runInSeparateProcess` for Mockery alias mocking)
1. `legacy_fallback_wenn_keine_agenda_items` — no agenda items → legacy path
2. `agenda_export_folgt_agenda_reihenfolge` — songs follow agenda sort_order, not serviceSong order
3. `agenda_export_informationen_an_gematchter_position` — announcements at pattern-matched agenda item
4. `agenda_export_informationen_am_anfang_als_fallback` — announcements prepended when no pattern matches
5. `agenda_export_ueberspringt_items_ohne_slides_oder_songs` — empty items not in playlist
6. `agenda_export_zaehlt_ungematchte_songs_als_skipped` — unmatched songs counted as skipped
7. `agenda_export_mit_slides_auf_agenda_item` — sermon slides on agenda item exported in order
8. `agenda_export_before_event_items_ausgeschlossen` — before-event items filtered out

### Test Infrastructure
- `mockProPresenterClasses()` uses Mockery `alias:` to mock static calls on ProFileGenerator/ProPlaylistGenerator
- `createSlide()` helper includes `thumbnail_filename` (NOT NULL constraint)
- `createSlideFile()` calls `Storage::fake('public')` for each slide
- Mock playlist output: `mock-playlist:{name}\n{item1}\n{item2}` — enables position assertions via `strpos()`
- 2 pre-existing test failures (HTTP route tests) due to empty propresenter parser src — not regressions

## 2026-03-29 — Finalize → Download integration tests

### Verification
- `ServiceController::download()` already calls `PlaylistExportService->generatePlaylist($service)` — no controller changes needed
- `PlaylistExportService::generatePlaylist()` already routes to agenda path or legacy fallback (Task 9)
- Main deliverable: integration tests proving full finalize → download flow

### Integration Tests Added (PlaylistExportTest.php)
1. `test_finalize_und_download_flow_mit_agenda_items` — creates service with agenda items (2 songs + sermon with slides), finalizes, downloads, verifies playlist ordering (song1 → sermon → song2)
2. `test_finalize_und_download_flow_legacy_ohne_agenda` — creates service without agenda items, finalizes, downloads, verifies legacy path produces .proplaylist file

### Test Patterns
- Both tests use `@runInSeparateProcess` + `@preserveGlobalState disabled` + `mockProPresenterClasses()` (Mockery alias)
- Full HTTP flow: POST finalize → refresh → GET download → assert response headers
- Agenda test verifies playlist content ordering via `strpos()` position comparison
- Legacy test verifies backward compat: no ServiceAgendaItems → uses `generatePlaylistLegacy()`

## 2026-03-29 — Settings.vue Agenda Configuration UI

### Implementation
- Updated `resources/js/Pages/Settings.vue` with new Agenda-Konfiguration section
- Added 4 new fields to the `fields` array with `section: 'agenda'` property:
  1. `agenda_start_title` — Ablauf-Start pattern
  2. `agenda_end_title` — Ablauf-Ende pattern
  3. `agenda_announcement_position` — Ankündigungen-Position with helpText
  4. `agenda_sermon_matching` — Predigt-Erkennung with helpText
- Added `section: 'macro'` to existing 4 macro fields for clear separation
- Updated macro section template: `fields.filter(f => f.section === 'macro')`
- Created new agenda section with identical field input structure
- Section displays:
  - Header: "Agenda-Konfiguration"
  - Subtitle: "Diese Einstellungen steuern, wie der Gottesdienst-Ablauf angezeigt und exportiert wird."
  - Fields with auto-save on blur (same `saveField()` function)
  - Conditional helpText display (only if `field.helpText` present)
  - Identical saving/saved/error indicators as macro section

### Build & Commit
- `npm run build` — ✓ 803 modules transformed, 17.94s gzip size for Edit component (expected growth)
- Committed: `feat(ui): add agenda settings to Settings page`

### Vue Field Definition Pattern
- Using `section` property to group related fields
- Template: `fields.filter(f => f.section === '{section}')`
- Optional `helpText` property displayed below input (agenda fields only, not macro fields)
- All fields use same `form[key]`, `saving[key]`, `saved[key]`, `errors[key]` reactive objects
- On blur: `saveField(field.key)` triggers PATCH to `route('settings.update')` endpoint

## 2026-03-29 — Service list status columns update

### Implementation
- Updated `ServiceController::index()` to compute and pass `agenda_slides_count`
- `agenda_slides_count` uses correlated subquery on `service_agenda_items`: counts non-song items (`service_song_id IS NULL`) that have at least 1 non-deleted slide via `whereExists()`
- Updated `has_sermon_slides` logic: if `Setting::get('agenda_sermon_matching')` is configured, checks agenda items matching the pattern for slides (using `AgendaMatcherService`); otherwise falls back to legacy `slides.type = 'sermon'` subquery
- Eager-loads `agendaItems` (non-song only) with slides for the sermon check in the map callback
- Updated `Index.vue` to show `{count} weitere Folien` when `agenda_slides_count > 0`, with `data-testid="agenda-slides-count"`

### Test Coverage (3 new tests)
1. `services_index_zaehlt_agenda_slides_fuer_nicht_song_items` — verifies non-song agenda items with slides count correctly (song items excluded)
2. `services_index_sermon_check_nutzt_agenda_matching_wenn_konfiguriert` — sermon slides via agenda item with setting
3. `services_index_sermon_ohne_agenda_slides_zeigt_false` — no slides on sermon agenda item → false

### Key Patterns
- `addSelect` with correlated subquery using `ServiceAgendaItem::query()` + `whereExists(Slide::query()...)`
- Sermon check done in PHP (map callback) because `fnmatch()` pattern matching can't be done in SQL
- `->with(['agendaItems' => fn ($q) => $q->whereNull('service_song_id')])` for efficient eager loading of only non-song agenda items
