# Bibliothèque Photo & Identification de Plantes — Plan d'implémentation

> **For Claude:** REQUIRED SUB-SKILL: Use superpowers:executing-plans to implement this plan task-by-task.

**Goal:** Ajouter une bibliothèque photo centralisée avec identification automatique de plantes via PlantNet (cloud) + YOLOv8 (fallback local dans un container dédié `ai-service`) et cache Redis.

**Architecture:** Backend FastAPI existant appelle PlantNet API en premier ; si indisponible, appelle le service `ai-service` interne (YOLOv8). Les résultats sont mis en cache Redis 7 jours. Un nouveau container `ai-service` héberge le modèle YOLO. Vue `BibliothequeView` + composants `PhotoGallery` et `PhotoIdentifyModal`.

**Tech Stack:** FastAPI, redis-py, httpx (déjà présent), ultralytics YOLOv8, Vue 3 + Composition API, Tailwind Gruvbox.

## Task 1 : ai-service — Container YOLO FastAPI

**Files:**
- Créer: `ai-service/Dockerfile`
- Créer: `ai-service/requirements.txt`
- Créer: `ai-service/main.py`
- Modifier: `docker-compose.yml`

**Étape 1 : Créer `ai-service/requirements.txt`**

```
fastapi==0.115.5
uvicorn[standard]==0.32.1
ultralytics==8.3.0
Pillow==11.1.0
python-multipart==0.0.12
```

from fastapi import FastAPI, File, UploadFile
from PIL import Image

app = FastAPI(title="AI Plant Detection Service")

_model = None
MODEL_CACHE_DIR = os.environ.get("MODEL_CACHE_DIR", "/models")


def get_model():
    global _model
    if _model is None:
        from ultralytics import YOLO
        os.makedirs(MODEL_CACHE_DIR, exist_ok=True)
        model_path = os.path.join(MODEL_CACHE_DIR, "plant-leaf.pt")
        if not os.path.exists(model_path):
            import subprocess
            subprocess.run([
                "python", "-c",
                f"from ultralyticsplus import YOLO; m=YOLO('foduucom/plant-leaf-detection-and-classification'); m.export(format='torchscript')"
            ], check=False)
        # Chargement direct depuis HuggingFace (téléchargé une seule fois)
        _model = YOLO("foduucom/plant-leaf-detection-and-classification")
    return _model


@app.get("/health")
def health():
    return {"status": "ok"}


@app.post("/detect")
async def detect(file: UploadFile = File(...)):
    data = await file.read()
    img = Image.open(io.BytesIO(data)).convert("RGB")

    model = get_model()
    results = model.predict(img, conf=0.25, iou=0.45, verbose=False)

    detections = []
    if results and results[0].boxes:
        boxes = results[0].boxes
        names = model.names
        for i in range(min(3, len(boxes))):
            cls_id = int(boxes.cls[i].item())
            conf = float(boxes.conf[i].item())
            detections.append({
                "class_name": names[cls_id],
                "confidence": round(conf, 3),
            })
    return detections
```

            "common_name": common_names[0] if common_names else "",
            "confidence": round(r.get("score", 0.0), 3),
            "image_url": (r.get("images", [{}]) or [{}])[0].get("url", {}).get("m", ""),
        })
    return results
```

**Étape 2 : Créer `backend/app/services/yolo_service.py`**

```python
import os
from typing import List

import httpx

AI_SERVICE_URL = os.environ.get("AI_SERVICE_URL", "http://localhost:8070")

# Mapping class_name YOLO → nom commun français (partiel)
_NOMS_FR = {

        results.append({
            "species": cls.replace("___", " — ").replace("_", " "),
            "common_name": _NOMS_FR.get(cls, cls.split("___")[0].replace("_", " ")),
            "confidence": det.get("confidence", 0.0),
            "image_url": "",
        })
    return results
```

**Étape 3 : Mettre à jour `.env.example`**

Ajouter ces lignes si elles n'existent pas :
```
PLANTNET_API_KEY=2b1088cHCJ4c7Cn2Vqq67xfve
AI_SERVICE_URL=http://ai-service:8070
REDIS_URL=redis://redis:6379
```

**Étape 4 : Commit**

```bash
git add backend/app/services/plantnet.py backend/app/services/yolo_service.py .env.example
git commit -m "feat(backend): services PlantNet et YOLO pour identification"
```

## Task 4 : Endpoint `/api/identify`

**Files:**
- Créer: `backend/app/routers/identify.py`
- Modifier: `backend/app/main.py`

**Étape 1 : Créer `backend/app/routers/identify.py`**

```python
from fastapi import APIRouter, File, UploadFile
from app.services import plantnet, yolo_service, redis_cache

router = APIRouter(tags=["identification"])


@router.post("/identify")
async def identify_plant(file: UploadFile = File(...)):
    image_bytes = await file.read()

    # 1. Cache Redis
    cached = redis_cache.get(image_bytes)
    if cached is not None:
        return {"source": "cache", "results": cached}

    # 2. PlantNet (cloud)
    results = await plantnet.identify(image_bytes, file.filename or "photo.jpg")

    # 3. Fallback YOLO si PlantNet indisponible
    if not results:
        results = await yolo_service.identify(image_bytes)
        source = "yolo"
    else:
        source = "plantnet"

    # 4. Mettre en cache
    redis_cache.set(image_bytes, results)

    return {"source": source, "results": results}
```

**Étape 2 : Enregistrer le router dans `backend/app/main.py`**

Dans la liste des imports, ajouter `identify` :
```python
from app.routers import (  # noqa
    gardens,
    plants,
    plantings,
    tasks,
    settings,
    media,
    tools,
    dictons,
    astuces,
    recoltes,
    lunar,
    meteo,
    identify,          # ← ajouter
)
```

Et ajouter dans la liste `app.include_router(...)` :
```python
app.include_router(identify.router, prefix="/api")
```

**Étape 3 : Tester manuellement (backend local)**

```bash
cd backend && uvicorn app.main:app --reload --port 8060
# Dans un autre terminal :
curl -s -X POST http://127.0.0.1:8060/api/identify \
  -F "file=@/chemin/vers/une_photo.jpg" | python3 -m json.tool
```
Attendu : `{"source": "plantnet"|"yolo"|"cache", "results": [...]}`

**Étape 4 : Commit**

```bash
git add backend/app/routers/identify.py backend/app/main.py
git commit -m "feat(backend): endpoint POST /api/identify PlantNet + YOLO fallback"
```

---

## Task 5 : Migration Media — champs `identified_*`

**Files:**
- Modifier: `backend/app/models/media.py`
- Modifier: `backend/app/migrate.py`

**Étape 1 : Ajouter les champs à `backend/app/models/media.py`**

```python
from datetime import datetime, timezone
from typing import Optional
from sqlmodel import Field, SQLModel


class Media(SQLModel, table=True):
    id: Optional[int] = Field(default=None, primary_key=True)
    entity_type: str  # jardin|plante|outil|plantation
    entity_id: int
    url: str
    thumbnail_url: Optional[str] = None
    titre: Optional[str] = None
    # Identification automatique
    identified_species: Optional[str] = None
    identified_common: Optional[str] = None
    identified_confidence: Optional[float] = None
    identified_source: Optional[str] = None  # "plantnet" | "yolo" | "cache"
    created_at: datetime = Field(default_factory=lambda: datetime.now(timezone.utc))
```

**Étape 2 : Ajouter la migration des colonnes dans `backend/app/migrate.py`**

Trouver la fonction qui applique les migrations par table et ajouter pour la table `media` :

```python
# Dans la section où on migre les tables existantes,
# ajouter ces colonnes si elles n'existent pas :
_add_column_if_missing(conn, "media", "identified_species", "TEXT")
_add_column_if_missing(conn, "media", "identified_common", "TEXT")
_add_column_if_missing(conn, "media", "identified_confidence", "REAL")
_add_column_if_missing(conn, "media", "identified_source", "TEXT")
```

(Utilise la fonction helper `_add_column_if_missing` déjà présente dans migrate.py)

**Étape 3 : Rebuilder le backend et vérifier**

```bash
docker compose up --build -d backend
docker compose logs backend --tail=20
```
Attendu : démarrage sans erreur, migrations appliquées.

**Étape 4 : Commit**

```bash
git add backend/app/models/media.py backend/app/migrate.py
git commit -m "feat(backend): champs identified_* sur Media pour stocker l'identification"
```

            "/api/identify",
            files={"file": ("test.jpg", FAKE_IMAGE, "image/jpeg")},
        )
    assert resp.status_code == 200
    data = resp.json()
    assert data["source"] == "yolo"


def test_identify_uses_cache():
    cached = [{"species": "Rosa canina", "common_name": "Églantier",
               "confidence": 0.9, "image_url": ""}]
    with patch("app.services.redis_cache.get", return_value=cached):
        resp = client.post(
            "/api/identify",
            files={"file": ("test.jpg", FAKE_IMAGE, "image/jpeg")},
        )
    assert resp.status_code == 200

## Task 9 : Vue `BibliothequeView.vue` + route + navigation

**Files:**
- Créer: `frontend/src/views/BibliothequeView.vue`
- Modifier: `frontend/src/router/index.ts`
- Modifier: `frontend/src/components/AppDrawer.vue`

**Étape 1 : Créer `frontend/src/views/BibliothequeView.vue`**

```vue
<template>
  <div class="p-4 max-w-4xl mx-auto">
    <div class="flex items-center justify-between mb-6">
      <h1 class="text-2xl font-bold text-green">📷 Bibliothèque</h1>
      <button @click="showIdentify = true"
        class="bg-green text-bg px-4 py-2 rounded-lg text-sm font-semibold hover:opacity-90">
        Identifier une plante
      </button>
    </div>

    <!-- Filtres -->
    <div class="flex gap-2 mb-4 flex-wrap">
      <button v-for="f in filters" :key="f.val"
        @click="activeFilter = f.val"
        :class="['px-3 py-1 rounded-full text-xs font-medium transition-colors',
          activeFilter === f.val ? 'bg-green text-bg' : 'bg-bg-soft text-text-muted hover:text-text']">
        {{ f.label }}
      </button>
    </div>

    <!-- Grille -->

      </div>
    </div>

    <!-- Lightbox -->
    <div v-if="lightbox" class="fixed inset-0 bg-black/80 z-50 flex items-center justify-center p-4"
      @click.self="lightbox = null">

          <div class="text-green font-semibold text-base">{{ lightbox.identified_common }}</div>
          <div class="italic">{{ lightbox.identified_species }}</div>
          <div class="text-xs mt-1">
            Confiance : {{ Math.round((lightbox.identified_confidence || 0) * 100) }}%
            — via {{ lightbox.identified_source }}
          </div>
        </div>
        <button class="mt-4 w-full text-text-muted hover:text-text text-sm" @click="lightbox = null">Fermer</button>
      </div>
    </div>

    <!-- Modal identification -->
    <PhotoIdentifyModal v-if="showIdentify" @close="showIdentify = false; fetchAll()" />
  </div>
</template>

<script setup lang="ts">
import { computed, onMounted, ref } from 'vue'
import axios from 'axios'
import PhotoIdentifyModal from '@/components/PhotoIdentifyModal.vue'

const medias = ref<any[]>([])
const loading = ref(false)
const lightbox = ref<any>(null)
const showIdentify = ref(false)
const activeFilter = ref('')

const filters = [
  { val: '', label: 'Toutes' },
  { val: 'plante', label: '🌱 Plantes' },
  { val: 'jardin', label: '🏡 Jardins' },
  { val: 'plantation', label: '🥕 Plantations' },
  { val: 'outil', label: '🔧 Outils' },
]

const filtered = computed(() =>
  activeFilter.value ? medias.value.filter(m => m.entity_type === activeFilter.value) : medias.value
)

function labelFor(type: string) {
  return { plante: '🌱', jardin: '🏡', plantation: '🥕', outil: '🔧' }[type] || '📷'

  // Charge toutes les photos en faisant plusieurs requêtes par type
  const types = ['plante', 'jardin', 'plantation', 'outil']
  const all: any[] = []
  // On utilise l'endpoint sans filtre entity_id en récupérant par type
  // Le backend actuel filtre par entity_type + entity_id,
  // donc on ajoute un endpoint GET /api/media/all ou on adapte
  // Pour l'instant on fait un appel direct à la DB via /api/media sans entity_id
  // → NÉCESSITE d'adapter le router media (voir étape 3)
  try {

    medias.value = data
  } catch {
    medias.value = []
  }
  loading.value = false
}

onMounted(fetchAll)
</script>
```

**Étape 2 : Ajouter l'endpoint `GET /api/media/all` dans `backend/app/routers/media.py`**

Ajouter avant le endpoint existant `GET /api/media` :

```python
@router.get("/media/all", response_model=List[Media])
def list_all_media(
    entity_type: Optional[str] = Query(default=None),
    session: Session = Depends(get_session),
):
    """Retourne tous les médias, optionnellement filtrés par entity_type."""
    q = select(Media)
    if entity_type:
        q = q.where(Media.entity_type == entity_type)
    return session.exec(q.order_by(Media.created_at.desc())).all()
```

Ajouter `Optional` à l'import :
```python
from typing import List, Optional
```

**Étape 3 : Ajouter la route dans `frontend/src/router/index.ts`**

Ajouter dans le tableau `routes` :
```typescript
{ path: '/bibliotheque', component: () => import('@/views/BibliothequeView.vue') },
```

**Étape 4 : Ajouter le lien dans `frontend/src/components/AppDrawer.vue`**

Dans le tableau `links`, ajouter après `{ to: '/plantes', label: 'Plantes' }` :
```typescript
{ to: '/bibliotheque', label: 'Bibliothèque' },
```

**Étape 5 : Rebuild et tester**

```bash
docker compose up --build -d
# Ouvrir http://127.0.0.1:8061/bibliotheque
```

**Étape 6 : Commit**

```bash
git add frontend/src/views/BibliothequeView.vue \
        frontend/src/router/index.ts \
        frontend/src/components/AppDrawer.vue \
        backend/app/routers/media.py
git commit -m "feat: vue BibliothequeView + route /bibliotheque + nav"
```

## Task 10 : Intégration `PhotoGallery` dans les fiches existantes (optionnel)

Cette tâche est optionnelle pour le MVP. Elle consiste à ajouter `<PhotoGallery>` dans les fiches plantes, jardins, etc.

**Exemple dans `PlantesView.vue` :** ajouter après la liste d'infos de chaque plante :
```vue
<PhotoGallery entity-type="plante" :entity-id="p.id" />
```

**Commit quand fait :**
```bash
git commit -m "feat(frontend): galerie photos dans fiches plantes"
```

---

## Task 11 : Build final et vérification

**Étape 1 : Lancer tous les tests backend**

```bash
cd backend && pytest tests/ -v
```
Attendu : tous PASSED

**Étape 2 : Build complet Docker**

```bash
docker compose down
docker compose up --build -d
docker compose logs --tail=30
```
Attendu : 4 services démarrés (backend, ai-service, redis, frontend)

**Étape 3 : Test fonctionnel**

1. Aller sur `http://127.0.0.1:8061/bibliotheque`
2. Cliquer "Identifier une plante"
3. Uploader une photo de tomate ou autre plante
4. Vérifier les résultats PlantNet (ou YOLO si offline)
5. Associer à une plante et vérifier dans la galerie

**Étape 4 : Commit final**

```bash
git commit -m "feat: bibliothèque photo + identification PlantNet/YOLO + cache Redis"
```
