# CRUD Clients & Projets - Plan d'implémentation

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

**Goal:** Implémenter le CRUD complet Client et Projet (backend API Platform + frontend Nuxt) avec pages dédiées, drawers latéraux pour ajout/modification, et fixtures de données.

**Architecture:** Deux entités Doctrine (Client, Project) avec relation ManyToOne optionnelle Project→Client. API Platform gère le CRUD via les attributs sur les entités (pas de controllers). Frontend avec pages dédiées : tableau pour les clients, cartes colorées pour les projets, drawers droits pour les formulaires.

**Tech Stack:** PHP 8.4 / Symfony 8 / API Platform 4 / Doctrine ORM / PostgreSQL (backend) — Nuxt 4 / Vue 3 / Pinia / Tailwind CSS / Malio UI Layer (frontend)

## Task 1 : Entité Client (Backend)

**Files:**
- Create: `src/Entity/Client.php`
- Create: `src/Repository/ClientRepository.php`

**Step 1: Créer le repository Client**

```php
<?php

declare(strict_types=1);

namespace App\Repository;

use App\Entity\Client;
use Doctrine\Bundle\DoctrineBundle\Repository\ServiceEntityRepository;
use Doctrine\Persistence\ManagerRegistry;

class ClientRepository extends ServiceEntityRepository
{
    public function __construct(ManagerRegistry $registry)
    {
        parent::__construct($registry, Client::class);
    }
}
```

**Step 2: Créer l'entité Client**

```php
<?php

declare(strict_types=1);

namespace App\Entity;

use ApiPlatform\Metadata\ApiResource;
use ApiPlatform\Metadata\Delete;
use ApiPlatform\Metadata\Get;
use ApiPlatform\Metadata\GetCollection;
use ApiPlatform\Metadata\Patch;
use ApiPlatform\Metadata\Post;
use App\Repository\ClientRepository;
use Doctrine\Common\Collections\ArrayCollection;
use Doctrine\Common\Collections\Collection;
use Doctrine\ORM\Mapping as ORM;
use Symfony\Component\Serializer\Attribute\Groups;

#[ApiResource(
    operations: [
        new GetCollection(),
        new Get(),
        new Post(security: "is_granted('ROLE_ADMIN')"),
        new Patch(security: "is_granted('ROLE_ADMIN')"),
        new Delete(security: "is_granted('ROLE_ADMIN')"),
    ],
    normalizationContext: ['groups' => ['client:read']],
    denormalizationContext: ['groups' => ['client:write']],
    order: ['name' => 'ASC'],
)]
#[ORM\Entity(repositoryClass: ClientRepository::class)]
class Client
{
    #[ORM\Id]
    #[ORM\GeneratedValue]
    #[ORM\Column]
    #[Groups(['client:read', 'project:read'])]
    private ?int $id = null;

    #[ORM\Column(length: 255)]
    #[Groups(['client:read', 'client:write', 'project:read'])]
    private ?string $name = null;

    #[ORM\Column(length: 255, nullable: true)]
    #[Groups(['client:read', 'client:write'])]
    private ?string $email = null;

    #[ORM\Column(length: 50, nullable: true)]
    #[Groups(['client:read', 'client:write'])]
    private ?string $phone = null;

    #[ORM\Column(length: 255, nullable: true)]
    #[Groups(['client:read', 'client:write'])]
    private ?string $street = null;

    #[ORM\Column(length: 255, nullable: true)]
    #[Groups(['client:read', 'client:write'])]
    private ?string $city = null;

    #[ORM\Column(length: 20, nullable: true)]
    #[Groups(['client:read', 'client:write'])]
    private ?string $postalCode = null;

    /** @var Collection<int, Project> */
    #[ORM\OneToMany(targetEntity: Project::class, mappedBy: 'client')]
    private Collection $projects;

    public function __construct()
    {
        $this->projects = new ArrayCollection();
    }

    // Getters et setters pour chaque propriété (getId, getName/setName, getEmail/setEmail,
    // getPhone/setPhone, getStreet/setStreet, getCity/setCity, getPostalCode/setPostalCode,
    // getProjects)
    // Suivre le même pattern fluent (return $this) que User.php
}
```

**Step 3: Générer et exécuter la migration**

Run (dans le container PHP) :
```bash
php bin/console doctrine:migrations:diff
php bin/console doctrine:migrations:migrate --no-interaction
```
Expected: Migration créée et exécutée, table `client` créée en base.

**Step 4: Vérifier l'API**

Run: `curl -s http://localhost:8082/api/clients | head -20` (après login)
Expected: Réponse Hydra vide `{"hydra:member":[],"hydra:totalItems":0}`

**Step 5: Commit**

```bash
git add src/Entity/Client.php src/Repository/ClientRepository.php migrations/
git commit -m "feat : add Client entity with CRUD API"
```

---

## Task 2 : Entité Project (Backend)

**Files:**
- Create: `src/Entity/Project.php`
- Create: `src/Repository/ProjectRepository.php`

**Step 1: Créer le repository Project**

```php
<?php

declare(strict_types=1);

namespace App\Repository;

use App\Entity\Project;
use Doctrine\Bundle\DoctrineBundle\Repository\ServiceEntityRepository;
use Doctrine\Persistence\ManagerRegistry;

class ProjectRepository extends ServiceEntityRepository
{
    public function __construct(ManagerRegistry $registry)
    {
        parent::__construct($registry, Project::class);
    }
}
```

**Step 2: Créer l'entité Project**

```php
<?php

declare(strict_types=1);

namespace App\Entity;

use ApiPlatform\Metadata\ApiResource;
use ApiPlatform\Metadata\Delete;
use ApiPlatform\Metadata\Get;
use ApiPlatform\Metadata\GetCollection;
use ApiPlatform\Metadata\Patch;
use ApiPlatform\Metadata\Post;
use App\Repository\ProjectRepository;
use Doctrine\ORM\Mapping as ORM;
use Symfony\Component\Serializer\Attribute\Groups;

#[ApiResource(
    operations: [
        new GetCollection(),
        new Get(),
        new Post(security: "is_granted('ROLE_ADMIN')"),
        new Patch(security: "is_granted('ROLE_ADMIN')"),
        new Delete(security: "is_granted('ROLE_ADMIN')"),
    ],
    normalizationContext: ['groups' => ['project:read']],
    denormalizationContext: ['groups' => ['project:write']],
    order: ['name' => 'ASC'],
)]
#[ORM\Entity(repositoryClass: ProjectRepository::class)]
class Project
{
    #[ORM\Id]
    #[ORM\GeneratedValue]
    #[ORM\Column]
    #[Groups(['project:read'])]
    private ?int $id = null;

    #[ORM\Column(length: 255)]
    #[Groups(['project:read', 'project:write'])]
    private ?string $name = null;

    #[ORM\Column(type: 'text', nullable: true)]
    #[Groups(['project:read', 'project:write'])]
    private ?string $description = null;

    #[ORM\Column(length: 7)]
    #[Groups(['project:read', 'project:write'])]
    private ?string $color = '#222783';

    #[ORM\ManyToOne(targetEntity: Client::class, inversedBy: 'projects')]
    #[ORM\JoinColumn(nullable: true, onDelete: 'SET NULL')]
    #[Groups(['project:read', 'project:write'])]
    private ?Client $client = null;

    // Getters et setters pour chaque propriété (getId, getName/setName, getDescription/setDescription,
    // getColor/setColor, getClient/setClient)
    // Suivre le même pattern fluent (return $this) que User.php
}
```

**Note importante pour API Platform :** Le champ `client` en écriture accepte un IRI (ex: `"/api/clients/1"`) ou `null`.

**Step 3: Générer et exécuter la migration**

Run (dans le container PHP) :
```bash
php bin/console doctrine:migrations:diff
php bin/console doctrine:migrations:migrate --no-interaction
```
Expected: Migration créée, table `project` avec foreign key vers `client`.

**Step 4: Commit**

```bash
git add src/Entity/Project.php src/Repository/ProjectRepository.php migrations/
git commit -m "feat : add Project entity with CRUD API and Client relation"
```

**Step 2: Créer la page Clients**

Créer `frontend/pages/clients.vue` :

```vue
<template>

```

**Step 3: Vérifier le rendu**

Run: `make dev-nuxt` puis naviguer vers `/clients`
Expected: Tableau vide (ou avec données si fixtures chargées), bouton "+ Ajouter un client", drawer s'ouvre au clic.

**Step 4: Commit**

```bash
git add frontend/pages/clients.vue frontend/components/ClientDrawer.vue
git commit -m "feat : add Clients page with table and drawer form"

## Task 9 : Navigation Sidebar + Traductions i18n

**Files:**
- Modify: `frontend/layouts/default.vue`
- Modify: `frontend/i18n/locales/fr.json`

**Step 1: Mettre à jour la sidebar**

Dans `frontend/layouts/default.vue`, ajouter le lien "Clients" sous "Projets" dans la nav :

```html
<!-- Ajouter après le NuxtLink Projets existant -->
<NuxtLink
    to="/clients"
    class="flex gap-3 px-4 py-3 text-md font-semibold text-black hover:bg-tertiary-500 hover:text-primary-500"
    active-class="bg-tertiary-500 text-primary-500"
>
    <Icon name="mdi:account-group-outline" size="24"/>
    <span class="self-baseline text-md">Clients</span>
</NuxtLink>
```

Aussi, mettre à jour le lien Projets pour pointer vers `/projects` (au lieu de `/project-list`) :

Changer `to="/project-list"` → `to="/projects"`

**Step 2: Ajouter les traductions**

Modifier `frontend/i18n/locales/fr.json` pour ajouter les clés de toast :

```json
{
    "errors": {
        "http": {
            "get": "Impossible de récupérer les données.",
            "post": "Impossible de créer la ressource.",
            "put": "Impossible de mettre à jour la ressource.",
            "patch": "Impossible de mettre à jour la ressource.",
            "delete": "Impossible de supprimer la ressource."
        },
        "auth": {
            "login": "Identifiants invalides.",
            "logout": "Impossible de se déconnecter.",
            "session": "Session expirée"
        }
    },
    "success": {
        "auth": {
            "login": "Connexion réussie.",
            "logout": "Déconnexion réussie."
        }
    },
    "clients": {
        "created": "Client créé avec succès.",
        "updated": "Client mis à jour avec succès.",
        "deleted": "Client supprimé avec succès."
    },
    "projects": {
        "created": "Projet créé avec succès.",
        "updated": "Projet mis à jour avec succès.",
        "deleted": "Projet supprimé avec succès."
    }
}
```

**Step 3: Commit**

```bash
git add frontend/layouts/default.vue frontend/i18n/locales/fr.json
git commit -m "feat : add Clients nav link and i18n translations"
```

## Task 10 : Mise à jour CLAUDE.md

**Files:**
- Modify: `CLAUDE.md`

**Step 1: Mettre à jour CLAUDE.md**

Ajouter dans la section structure les nouveaux fichiers et patterns. Points à ajouter/mettre à jour :

- Ajouter `Client` et `Project` dans les entités documentées
- Ajouter les fixtures complètes (3 clients, 4 projets)
- Documenter le pattern Drawer (AppDrawer + formulaires spécifiques)
- Documenter les services frontend (useClientService, useProjectService)
- Documenter les DTOs (Client, ClientWrite, Project, ProjectWrite)
- Documenter l'utilitaire Hydra (`utils/api.ts`)
- Documenter le composant ColorPicker
- Mettre à jour la structure des dossiers

**Step 2: Commit**

```bash
git add CLAUDE.md

```

---

## Task 11 : Tests manuels de bout en bout

**Step 1: Recharger les fixtures**

Run: `make db-reset` ou `make fixtures`
Expected: BDD reset avec admin + 3 clients + 4 projets

**Step 2: Tester l'API Client via curl**

```bash
# Login
curl -c cookies.txt -X POST http://localhost:8082/login_check \
  -H 'Content-Type: application/json' \
  -d '{"username":"admin","password":"admin"}'

# GET clients
curl -b cookies.txt http://localhost:8082/api/clients
```
Expected: Liste de 3 clients au format Hydra

**Step 3: Tester l'API Project via curl**

```bash
curl -b cookies.txt http://localhost:8082/api/projects
```
Expected: Liste de 4 projets au format Hydra, chaque projet avec `client` imbriqué ou null

**Step 4: Tester le frontend**

1. Naviguer vers `http://localhost:8082/`
2. Se connecter avec `admin` / `admin`
3. Cliquer "Projets" dans la sidebar → page avec 4 cartes colorées
4. Cliquer "+ Ajouter un projet" → drawer s'ouvre, remplir et enregistrer
5. Cliquer "Clients" dans la sidebar → page avec tableau de 3 clients
6. Cliquer sur une ligne → drawer s'ouvre avec les données pré-remplies
7. Cliquer "+ Ajouter un client" → drawer vide s'ouvre

**Step 5: Commit final si ajustements**

```bash
git add -A
git commit -m "fix : adjustments after manual testing"
```
