Use UUID instead of auto-increment

You don't want to use auto incrementing ID in your model?

Migration:

1Schema::create('users', function (Blueprint $table) {
2    // $table->increments('id');
3    $table->uuid('id')->unique();
4});

Laravel 9 and above:

 1use Illuminate\Database\Eloquent\Concerns\HasUuids;
 2use Illuminate\Database\Eloquent\Model;
 3 
 4class Article extends Model
 5{
 6    use HasUuids;
 7 
 8    // ...
 9}
10 
11$article = Article::create(['title' => 'Traveling to Europe']);
12 
13$article->id; // "8f8e8478-9035-4d23-b9a7-62f4d2612ce5"

Laravel 8 and below:

• In PHP 7.4.0 and above:

 7    protected $keyType = 'string';

10    {
11        parent::boot();
12 
13        self::creating(fn (User $model) => $model->attributes['id'] = Str::uuid());
14        self::saving(fn (User $model) => $model->attributes['id'] = Str::uuid());
15    }
