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

Add to the modal:

protected $fillable = array('*');

protected $guarded = ['id'];
