Intelligent Laravel scaffolding. Reads your database schema and writes model relationships, controllers, API resources, form requests, and tests — automatically.

composer require julio/capyrel

Supports Laravel 11 & 12 · PHP 8.2+ · MySQL · PostgreSQL · SQLite · MongoDB

What it does

Capyrel reads your database (tables, columns, foreign keys, indexes) and reverse-engineers every Eloquent relationship. It then writes the code for you across your entire stack.

php artisan model:scaffold     # writes models, controllers, blade
php artisan model:map          # visual relationship diagram
php artisan model:resources    # generates API Resource classes
php artisan model:requests     # generates Form Request classes
php artisan model:tests        # generates Pest relationship tests
php artisan migrate:safe       # scans migrations for dangerous patterns
php artisan model:watch        # live-updates models when migrations change

Installation

composer require julio/capyrel

Laravel's auto-discovery registers the service provider. No config publish required.

Commands

model:scaffold

Detects all relationships and scaffolds models, controllers, and blade views.

php artisan model:scaffold              # interactive wizard
php artisan model:scaffold User         # one model only
php artisan model:scaffold --dry-run    # preview without writing
php artisan model:scaffold --models     # models only
php artisan model:scaffold --controllers
php artisan model:scaffold --views
php artisan model:scaffold --force      # skip confirmations
php artisan model:scaffold --connection=pgsql

What it writes to each model:

// capyrel: posts.user_id
public function posts(): HasMany
{
    return $this->hasMany(Post::class);
}

// capyrel: pivot: role_user
public function roles(): BelongsToMany
{
    return $this->belongsToMany(Role::class);
}

What it writes to each controller:

public function index()
{
    $users = User::with(['posts', 'profile', 'roles'])->paginate(15);
    return view('users.index', compact('users'));
}

What it adds to blade views:

{{-- CAPYREL: hasMany → Post --}}
@forelse($user->posts as $post)
    {{-- $post->title --}}
@empty
    <p>No posts.</p>
@endforelse

model:map

Generates a visual map of every model and relationship.

php artisan model:map                       # ASCII tree in terminal
php artisan model:map --format=mermaid      # Mermaid.js diagram
php artisan model:map --format=both
php artisan model:map --save=docs/schema.md

ASCII output:

User
├── hasMany          ──▶ Post
├── hasOne           ──▶ Profile
├── belongsToMany    ──▶ Role
└── hasManyThrough   ──▶ Comment  (via Post)

Mermaid output (paste into GitHub markdown or mermaid.live):

erDiagram
    User ||--o{ Post : "hasMany"
    User ||--|| Profile : "hasOne"
    User }o--o{ Role : "belongsToMany"

model:resources

Generates API Resource classes with whenLoaded() on all relationships — N+1 impossible by design.

php artisan model:resources
php artisan model:resources User
php artisan model:resources --force   # overwrite existing
php artisan model:resources --dry-run

Generated UserResource.php:

public function toArray(Request $request): array
{
    return [
        'id'    => $this->id,
        'name'  => $this->name,
        'email' => $this->email,

        // capyrel: relationships — only included when eager-loaded
        'posts'   => PostResource::collection($this->whenLoaded('posts')),
        'profile' => new ProfileResource($this->whenLoaded('profile')),
        'roles'   => RoleResource::collection($this->whenLoaded('roles')),
    ];
}

model:requests

Generates Store and Update Form Request classes with validation rules derived from column types, constraints, and naming conventions.

php artisan model:requests
php artisan model:requests Post
php artisan model:requests --force
php artisan model:requests --dry-run

Generated StorePostRequest.php:

public function rules(): array
{
    return [
        'title'   => ['required', 'string', 'max:255'],
        'body'    => ['required', 'string'],
        'user_id' => ['required', 'integer', 'exists:users,id'],
        'slug'    => ['required', 'string', Rule::unique('posts', 'slug')],
    ];
}

Column → rule mapping: varchar(255) → max:255, nullable → removes required, *_id FK → exists:table,id, unique index → Rule::unique(), column named email → adds email rule, column named *_url → adds url rule.

model:tests

Generates Pest test files for every detected relationship.

php artisan model:tests
php artisan model:tests User
php artisan model:tests --dry-run
php artisan model:tests --force

Generated tests/Models/UserTest.php:

describe('User relationships', function () {
    it('User::posts() returns a HasMany', function () {
        expect((new User)->posts())->toBeInstanceOf(HasMany::class);
    });

    it('User::profile() returns a HasOne', function () {
        expect((new User)->profile())->toBeInstanceOf(HasOne::class);
    });

    it('User can attach Role', function () {
        $user = User::factory()->create();
        $role = Role::factory()->create();
        $user->roles()->attach($role->id);
        expect($user->fresh()->roles)->toHaveCount(1);
    })->skip('Requires factory and DB — remove skip() to enable');
});

Run with: php artisan test --filter=relationships

migrate:safe

Scans pending migrations for dangerous patterns before running them.

php artisan migrate:safe          # scan + confirm + run
php artisan migrate:safe --check  # scan only, never runs
php artisan migrate:safe --force  # run without confirmation

Patterns detected:

model:watch

Watches database/migrations/ for changes and automatically injects new relationship methods into model files.

php artisan model:watch
php artisan model:watch --connection=mysql
php artisan model:watch --interval=3   # poll every 3 seconds

Capyrel Watch Mode

✔ Initial scan complete — 18 relationships detected

[14:32:11] New migration: 2026_05_13_143211_add_team_id_to_posts.php
✔ Post: 1 new relationship(s) injected
  + belongsTo(Team) via posts.team_id

Health check

Every model:scaffold run includes a full health check on your schema:

Database support

For MongoDB, capyrel samples live documents to discover field names. For empty collections, it falls back to reading your migration files.

Requirements

• PHP 8.2+
• Laravel 11.x or 12.x
