A little trait to add to models that will have Uuids
<?php
// Example usage in a model:
class ExampleModel extends Model
{
use HasUuid;
protected $primaryKey = 'uuid';
public $incrementing = false;
}
// The Trait:
trait HasUuid
{
public static function bootHasUuid()
{
static::creating(function ($model) {
if (! $model->{$model->getKeyName()}) {
$model->{$model->getKeyName()} = static::generateUuid();
}
});
}
public static function generateUuid()
{
return (string) Illuminate\Support\Str::uuid();
}
}

Didn't work for me. Ended up using:

<?php
namespace App\Traits;

trait Uuids
{
    /**
     * Boot function from laravel.
     */
    protected static function boot()
    {
        parent::boot();

        static::creating(function ($model) {
            $model->{$model->getKeyName()} = (string) \Illuminate\Support\Str::uuid();
        });
    }
}
