在behavior Yii2中访问模型的当前实例

use yii\base\Behavior;
use yii\db\ActiveRecord;

class MyBehavior extends Behavior
{
    public function events()
    {
        return [
            ActiveRecord::EVENT_BEFORE_SAVE => 'beforeSave',
        ];
    }

    public function beforeSave($event)
    {
        $model = $this->owner; // 获取当前模型实例
        // 在这里可以访问和操作当前模型实例
    }
}

use yii\db\ActiveRecord;

class MyModel extends ActiveRecord
{
    public function behaviors()
    {
        return [
            MyBehavior::className(),
        ];
    }
}
