 ## 5. PostgreSQL — Schema & Data Flow
-### Table `recipes` (only app table today)
+### Relational schema (`scripts/schema.sql`)
-Created by `init_db()` in `helpers.php` if missing:
+Created by `ensure_recipe_schema()` on first DB use. Legacy JSONB `recipes.data` is migrated once automatically.
-| Column       | Type        | Role |
+| Table | Role |
-|-------------|-------------|------|
+|-------|------|
-| `slug`      | `VARCHAR(255)` PRIMARY KEY | Stable recipe ID (URLs: `recipe.php?slug=…`) |
+| `recipes` | slug, hero, times, servings, nutrition columns, featured, coming_soon |
-| `data`      | `JSONB` NOT NULL | **Entire recipe document** (title, i18n, ingredients, steps, nutrition, …) |
+| `recipe_translations` | title, description, category, difficulty (en/de) |
-| `created_at`| `TIMESTAMP` | Auto on insert |
+| `recipe_tags`, `recipe_ingredients`, `recipe_utensils`, `recipe_steps` | Ordered lists per language |
 | `updated_at`| `TIMESTAMP` | Set on `ON CONFLICT` update in `save_recipes()` |
-**Design choice:** Document-in-a-row (JSONB), not normalized columns. PHP already works with JSON arrays; avoids schema migrations for every new recipe field. PostgreSQL can still query inside JSON (`data->'i18n'->'en'->>'title'`).
+PHP still exposes the same nested arrays (`i18n`, `nutrition`, …) via `hydrate_recipes_from_db()`.
 ### Runtime flow
-1. `get_db_connection()` in `config.php` parses `DATABASE_URL` → PDO `pgsql:` DSN.
+1. `DATABASE_URL` required → `require_database()` or HTTP 503 (`maintenance/db-unavailable.php`).
-2. If no URL or connection fails → `load_recipes_local()` reads `data/recipes.json` only.
+2. `load_recipes()` → SQL → PHP arrays for templates.
-3. If connected → `init_db()` once per request (static flag): `CREATE TABLE IF NOT EXISTS`, then if `COUNT(*) = 0` → seed all rows from `data/recipes.json`.
+3. Admin: `save_recipe()`, `delete_recipe()`, `clear_featured_recipes()`.
-4. `load_recipes()` / `load_recipe_by_slug()` decode `data` JSONB to PHP arrays.
+4. One-time import: `php scripts/db-seed.php` from `data/recipes.json` (not read at runtime).
 5. `save_recipes()` (admin): upsert all recipes in Postgres **and** write `data/recipes.json` as backup.
 ### `config.php` functions
- `load_env()` — parses `.env` into `getenv()` / `$_ENV` / `$_SERVER`.
+- `load_env()` — parses `.env`.
- `get_firebase_config()` — returns Firebase web config array from `FIREBASE_*` env vars. **Required** by `partials/head.php` and `admin.php`. Was accidentally removed in postgres commit `e7f35d7`; restored (undefined function caused HTTP 500).
+- `get_db_connection()` — PDO or `null`.
- `get_db_connection()` — returns `PDO` or `null`; logs failures, does not throw.

 ### `.env` rules for agents
 - Copy from `.env.example`; never commit `.env`.
 - **Local:** use `127.0.0.1` Docker URL above.
- **Railway production:** `postgres.railway.internal` only works **inside** Railway network — not from local WSL. For local access to hosted DB use Railway **public** proxy URL from dashboard, or prefer Docker for dev.
+- **`DATABASE_URL` is mandatory** for recipe pages; omitting it shows the DB unavailable page.
 - **Firebase:** `FIREBASE_API_KEY`, `FIREBASE_AUTH_DOMAIN`, `FIREBASE_PROJECT_ID`, `FIREBASE_STORAGE_BUCKET`, `FIREBASE_MESSAGING_SENDER_ID`, `FIREBASE_APP_ID` — empty values break client `firebase.initializeApp()` in browser.
 - Omit `DATABASE_URL` entirely to force JSON-only mode (UI work without Postgres).
 ### Environment separation (important)
 - One database per environment (local Docker / staging / production).
 - Never point a dev branch `.env` at production Postgres.
- Export/import between envs: `pg_dump` / `psql` when needed; document URLs in platform secrets (Railway variables), not in repo.

 ## 🗄️ Postgres in diesem Projekt (Kurzüberblick)
-FlixCooks nutzt **eine Tabelle** – kein klassisches „eine Spalte pro Rezeptfeld“-Schema:
+Rezepte liegen in **normalisierten SQL-Tabellen** (kein JSONB-Blob, kein Laufzeit-Fallback auf Dateien):
-| Spalte       | Typ        | Bedeutung |
+| Tabelle | Inhalt |
-|-------------|------------|-----------|
+|---------|--------|
-| `slug`      | `VARCHAR`  | Eindeutige ID des Rezepts (URL: `/recipe.php?slug=...`) |
+| `recipes` | Slug, Zeiten, Hero-URL, Nährwerte, `featured`, `coming_soon` |
-| `data`      | `JSONB`    | **Gesamtes** Rezept als JSON (Titel, Zutaten, Schritte, i18n, …) |
+| `recipe_translations` | Titel, Beschreibung, Kategorie, Schwierigkeit (EN/DE) |
-| `created_at`| `TIMESTAMP`| Erstellzeit |
+| `recipe_tags` | Tags pro Sprache |
-| `updated_at`| `TIMESTAMP`| Letzte Änderung (wird beim Update gesetzt) |
+| `recipe_ingredients` | Zutatenzeilen |
 | `recipe_utensils` | Werkzeugzeilen |
 | `recipe_steps` | Schritte inkl. Video-URL und Timer |
-**Warum JSONB?** Das Rezept ist in PHP/JSON ohnehin ein Objekt. Statt 20+ SQL-Spalten zu pflegen, speichert ihr ein Dokument pro Zeile. PostgreSQL kann in `JSONB` trotzdem indexieren und abfragen (`data->>'title'`), wenn ihr später filtern wollt.
+Schema: `scripts/schema.sql`. PHP baut daraus dieselben Arrays wie früher (`i18n.en`, `nutrition`, …), damit Templates unverändert bleiben.
-**Ablauf beim ersten Aufruf mit leerer DB:**
+**Ablauf:**
-1. `config.php` liest `DATABASE_URL` → PDO-Verbindung.
+1. `DATABASE_URL` in `.env` → Verbindung über `config.php`.
-2. `init_db()` in `helpers.php` erstellt `recipes`, falls nicht vorhanden.
+2. Beim ersten Request: Tabellen anlegen (`ensure_recipe_schema()`). Alte JSONB-Tabelle wird einmalig migriert.
-3. Ist die Tabelle leer → Import aus `data/recipes.json`.
+3. `load_recipes()` liest per SQL; ohne DB → HTTP 503 (`maintenance/db-unavailable.php`).
-4. `load_recipes()` liest alle Zeilen, dekodiert `data` zurück zu PHP-Arrays.
+4. Admin: `save_recipe()` / `delete_recipe()` – direkt in die Tabellen.
-**Admin speichern:** `save_recipes()` schreibt nach Postgres **und** aktualisiert `data/recipes.json` als Backup.
+**Einmalig Daten laden:** `php scripts/db-seed.php` (aus `data/recipes.json`).
