laravel-uuid UUID未填写save()

Attempting to use this, but when saving no UUID is entered into the db.

Here is my setup:

DB: Name: uuid char(36) utf8mb4_unicode_ci

use Illuminate\Database\Eloquent\Model;
use Cviebrock\EloquentSluggable\Sluggable;
use Emadadly\LaravelUuid\Uuids;

class Account extends Model
{
   use Uuids;

   protected $fillable = [
      'name', 'tname', 'short', 'uuid'
   ];

   protected $guarded = [
      'id'
   ];

Controller:

public function saveUUID(Account $account){
$example = new Account;

    $example->name = 'test';
    $example->short = 'FIVE';
    $example->industry_id = 1;
    $example->user_id = 1;
    $example->status_id = 36;
    $example->save();

return response()->json(['example' => $example]);
}

The uuid field is left null, and the response for $example does not include the uuid.

What am i missing or doing wrong?

    I would personally create a UUID trait like the following.

    <?php
    
    use Ramsey\Uuid\Uuid;
    
    trait HasUuid
    {
    
    protected static function bootHasUuid()
    {
        /**
         * Attach to the 'creating' Model Event to provide a UUID
         * for the `uuid` field
         */
        static::creating(function ($model) {
            $columnName = static::getUuidColumn();
    
            $model->$columnName = Uuid::uuid4();
        });
    }
    
    /* Getters and Setters */
    
    
    public function getUuidAttribute()
    {
        $columnName = static::getUuidColumn();
    
        return $this->attributes[$columnName];
    }
    
    protected static function getUuidColumn()
    {
        if (isset(static::$uuidColumn)) {
            return static::$uuidColumn;
        }
        return 'uuid';
    }
    

    Now in you model you can include HasUuid trait

    <?php
    
    class Model {
    use HasUuid
    //.....
    }
    

    FYI if your uuid field is called something else in you class model you can declare the filed like so static $uuidColumn = 'user_uuid':.

    Trait will handle the rest
