我有这样的模型，我想在SetFooAttribute中获取属性.但是所有时候$ this-> getAttribute('id')都是空的！有没有办法访问ID?

I have model like this where i want to get a attribute inside SetFooAttribute. but all time $this->getAttribute('id') is empty! is there a way to access id ?

{

    public static function boot()
    {
        parent::boot();

        static::created(function($model)
        {
            $model->uuid = Uuid::generate(4)->string;
            $model->save();
        });
    }

    public function setFooAttribute($value)
        {
            $this->attributes['foo'] = $value.'-'.$this->getAttribute('id');
        }

推荐答案

您应使用 getKey()方法来获取模型主键的值.像$this->getKey()

You should use getKey() method to get the value of the model's primary key. Use it like $this->getKey()
