Model Template

<?php

declare(strict_types=1);

namespace App\Models;

final class Post extends Model
{
    protected $fillable = ['title', 'slug', 'content', 'user_id'];

    protected function casts(): array
    {
        return [
            'status' => PostStatus::class,
            'published_at' => 'datetime',
        ];
    }

    public function user(): BelongsTo
    {
        return $this->belongsTo(User::class);
    }

    public function scopePublished(Builder $query): Builder
    {
        return $query->where('status', PostStatus::Published);
    }
}

Query Optimization

// Eager loading (prevent N+1)
$posts = Post::with(['user', 'comments.user'])->get();

// Chunking for large datasets
User::chunk(100, function ($users) {
    foreach ($users as $user) { }
});
