# 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
