How to reset Yii2 model?

Question

Yii

Actually there is such a code

<?php
namespace console\controllers;

use yii\console\Controller;
use common\models\Settings;
use Yii;

class SettingsController extends Controller {
  public function actionInit() {
    $settings = Yii::$app->params['settings'];
    foreach ($settings as $key => $param) {
      if(Settings::find(['key' => $key])->one() === NULL) {
        $obj = new Settings;
        $obj->key = $key;
        $obj->type = $param[0];
        $obj->value = $param[1];
        if($obj->validate()) {
          $obj->save();
        } else {
          print 'Error on ' . $key . '\n' . $obj->errors;
        }
        unset($obj);
      }
    }
  }
}

It brings the parameters from the file into the database through the model.
The foreach itself passes through the parameters normally, and the first parameter is successfully entered into the database, but the following calls to Settings::find return the same object, so subsequent parameters are no longer entered into the database.
How to deal with it?

Answer 1

Solved my problem myself, use exists()
Settings::find()->where(['key' => $key])->exists()

Answer 2

You are tough)) As a rule, requests in a loop are not the best idea (there are exceptions, of course, but this is not the case).
I recommend that you first make a selection of available settings by keys, then insert the difference with a batch.
If in params['settings'] someone mistakenly sets 'key' => 'value', your system will not work correctly.
