Example usage (get file from HTTP request):

    /* app\controllers\UploadController.php */
    
    public function actionImage()
    {
        Yii::$app->response->format = 'json';
        $file = UploadedFile::getInstanceByName('file');
     
        $model = Yii::$app->media->createFileByUploadedFile($file, 'avatar');

        return [
            'image' => $model->toJSON()
        ];
    }

Console commands

To use console commands you should create a file FilestorageController.php at your commands folders.

<?php

namespace app\commands;

class FilestorageController extends \ozerich\filestorage\console\FilestorageController
{
    // className of your File model
    public $modelClass = 'app\models\Image';
}

If you did not use console commands at your projects, don't forget to confugure them, you should insert code in your config/console.php

    'controllerNamespace' => 'app\commands',

List of commands:

1. php yii filestorage/fix-thumbnails - Regenerate thumbnails of all images
