Давайте начнем с выполнения вашего задания. Для этого проекта мы создадим миграции, сиды, модели и контроллеры. Также добавим валидацию и загрузку изображений.

### Шаг 1: Создание миграций

1. Миграция для таблицы `genres`:

php artisan make:migration create_genres_table

2. Миграция для таблицы `movies`:

php artisan make:migration create_movies_table

3. Миграция для таблицы `genre_movie` (таблица связи):

php artisan make:migration create_genre_movie_table

Теперь заполним эти миграции.

database/migrations/xxxx_xx_xx_create_genres_table.php:

use Illuminate\Database\Migrations\Migration;
use Illuminate\Database\Schema\Blueprint;
use Illuminate\Support\Facades\Schema;

class CreateGenresTable extends Migration
{
    public function up()
    {
        Schema::create('genres', function (Blueprint $table) {
            $table->id();
            $table->string('name');
            $table->timestamps();
        });
    }

    public function down()
    {
        Schema::dropIfExists('genres');
    }
}

database/migrations/xxxx_xx_xx_create_movies_table.php:

use Illuminate\Database\Migrations\Migration;
use Illuminate\Database\Schema\Blueprint;
use Illuminate\Support\Facades\Schema;

class CreateMoviesTable extends Migration
{
    public function up()
    {
        Schema::create('movies', function (Blueprint $table) {
            $table->id();
            $table->string('title');
            $table->boolean('is_published')->default(false);
            $table->string('poster_url')->nullable();
            $table->timestamps();
        });
    }

    public function down()
    {
        Schema::dropIfExists('movies');
    }
}

database/migrations/xxxx_xx_xx_create_genre_movie_table.php:

use Illuminate\Database\Migrations\Migration;
use Illuminate\Database\Schema\Blueprint;
use Illuminate\Support\Facades\Schema;

class CreateGenreMovieTable extends Migration
{
    public function up()
    {
        Schema::create('genre_movie', function (Blueprint $table) {
            $table->id();
            $table->foreignId('genre_id')->constrained()->onDelete('cascade');
            $table->foreignId('movie_id')->constrained()->onDelete('cascade');
            $table->timestamps();
        });
    }

    public function down()
    {
        Schema::dropIfExists('genre_movie');
    }
}

### Шаг 2: Создание сидов

Создадим сиды для тестового заполнения таблиц.

database/seeders/GenreSeeder.php:

use Illuminate\Database\Seeder;
use App\Models\Genre;

class GenreSeeder extends Seeder
{
    public function run()
    {
        Genre::create(['name' => 'Action']);
        Genre::create(['name' => 'Comedy']);
        Genre::create(['name' => 'Drama']);
    }
}

database/seeders/MovieSeeder.php:

use Illuminate\Database\Seeder;
use App\Models\Movie;

class MovieSeeder extends Seeder
{
    public function run()
    {
        Movie::create([
            'title' => 'Movie 1',
            'is_published' => false,
            'poster_url' => 'default_poster.png'
        ]);

        Movie::create([
            'title' => 'Movie 2',
            'is_published' => true,
            'poster_url' => 'default_poster.png'
        ]);
    }
}

database/seeders/DatabaseSeeder.php:

use Illuminate\Database\Seeder;

class DatabaseSeeder extends Seeder
{
    public function run()
    {
        $this->call(GenreSeeder::class);
        $this->call(MovieSeeder::class);
    }
}

### Шаг 3: Создание моделей

app/Models/Genre.php:

namespace App\Models;

use Illuminate\Database\Eloquent\Factories\HasFactory;
use Illuminate\Database\Eloquent\Model;

class Genre extends Model
{
    use HasFactory;

    protected $fillable = ['name'];

    public function movies()
    {
        return $this->belongsToMany(Movie::class);
    }
}

app/Models/Movie.php:

namespace App\Models;

use Illuminate\Database\Eloquent\Factories\HasFactory;
use Illuminate\Database\Eloquent\Model;

class Movie extends Model
{
    use HasFactory;

    protected $fillable = ['title', 'is_published', 'poster_url'];

    public function genres()
    {
        return $this->belongsToMany(Genre::class);
    }
}

### Шаг 4: Создание контроллеров

app/Http/Controllers/GenreController.php:

namespace App\Http\Controllers;

use App\Models\Genre;
use Illuminate\Http\Request;

class GenreController extends Controller
{
    public function index()
    {
        return Genre::all();
    }

    public function show($id)
    {
        return Genre::with('movies')->findOrFail($id);
    }

    // Other CRUD methods...
}

app/Http/Controllers/MovieController.php:

namespace App\Http\Controllers;

use App\Models\Movie;
use Illuminate\Http\Request;
use Illuminate\Support\Facades\Storage;

class MovieController extends Controller
{
    public function index()
    {
        return Movie::paginate(10);
    }

    public function show($id)
    {
        return Movie::with('genres')->findOrFail($id);
    }

    public function store(Request $request)
    {
        $request->validate([
            'title' => 'required|string|max:255',
            'poster' => 'image|mimes:jpeg,png,jpg,gif,svg|max:2048'
        ]);

        $posterPath = $request->file('poster') ? $request->file('poster')->store('posters') : 'default_poster.png';

        $movie = Movie::create([
            'title' => $request->input('title'),
            'poster_url' => $posterPath,
            'is_published' => false
        ]);

        return response()->json($movie, 201);
    }

    public function update(Request $request, $id)
    {
        $movie = Movie::findOrFail($id);

        $request->validate([
            'title' => 'required|string|max:255',
            'poster' => 'image|mimes:jpeg,png,jpg,gif,svg|max:2048'
        ]);

        if ($request->hasFile('poster')) {
            Storage::delete($movie->poster_url);
            $posterPath = $request->file('poster')->store('posters');
            $movie->poster_url = $posterPath;
        }

        $movie->title = $request->input('title');
        $movie->save();

        return response()->json($movie, 200);
    }

    public function destroy($id)
    {
        $movie = Movie::findOrFail($id);
        Storage::delete($movie->poster_url);
        $movie->delete();

        return response()->json(null, 204);
    }

    public function publish($id)
    {
        $movie = Movie::findOrFail($id);
        $movie->is_published = true;
        $movie->save();

        return response()->json($movie, 200);
    }
}

### Шаг 5: Настройка маршрутов

routes/api.php:

use App\Http\Controllers\GenreController;
use App\Http\Controllers\MovieController;

Route::get('genres', [GenreController::class, 'index']);
Route::get('genres/{id}', [GenreController::class, 'show']);

Route::get('movies', [MovieController::class, 'index']);
Route::get('movies/{id}', [MovieController::class, 'show']);
Route::post('movies', [MovieController::class, 'store']);
Route::put('movies/{id}', [MovieController::class, 'update']);
Route::delete('movies/{id}', [MovieController::class, 'destroy']);
Route::post('movies/{id}/publish', [MovieController::class, 'publish']);

Это базовая структура для выполнения вашего задания. Вы можете дополнительно кастомизировать и улучшать код по мере необходимости.
