Laravel lararvel uuid作为主键

我正在尝试将uuid设置为Laravel模型中的主键。我已经在我的模型中设置了一个启动方法，这样我就不必每次创建和保存模型时都手动创建它。我有一个控制器，它只创建模型并将其保存在数据库中

它正确地保存在数据库中，但当控制器返回id值时，它总是返回0。如何使它实际返回它在数据库中创建的值

模型

控制器

您需要将keyType更改为string，并将incrementing更改为false。因为它不是递增的

public $incrementing = false;
protected $keyType = 'string';

此外，我有一个特点，我只是添加到那些有UUID键的模型中。这是非常灵活的。这源于，我对它进行了一些小的调整，以解决我在集中使用它时发现的问题

use Illuminate\Database\Eloquent\Model;
use Ramsey\Uuid\Uuid;

/**
 * Class Uuid.
 * Manages the usage of creating UUID values for primary keys. Drop into your models as
 * per normal to use this functionality. Works right out of the box.
 * Taken from: http://garrettstjohn.com/entry/using-uuids-laravel-eloquent-orm/
 */
trait UuidForKey
{

    /**
     * The "booting" method of the model.
     */
    public static function bootUuidForKey()
    {
        static::retrieved(function (Model $model) {
            $model->incrementing = false;  // this is used after instance is loaded from DB
        });

        static::creating(function (Model $model) {
            $model->incrementing = false; // this is used for new instances

            if (empty($model->{$model->getKeyName()})) { // if it's not empty, then we want to use a specific id
                $model->{$model->getKeyName()} = (string)Uuid::uuid4();
            }
        });
    }

    public function initializeUuidForKey()
    {
        $this->keyType = 'string';
    }
}

希望这有帮助

public $incrementing = false;
protected $keyType = 'string';
