Why doesn't Yii2 ActiveRecord Model delete?

Question

Yii

I don't understand why Call to a member function delete() error


Here is the model

<?php
namespace common\models;

use Yii;
use yii\base\NotSupportedException;
use yii\db\ActiveRecord;

/**
 * UserToSection model
 *
 * @property integer $id
 * @property integer $user_id
 * @property integer $section_id
 */
class UserToSection extends ActiveRecord
{
  


    /**
     * @inheritdoc
     */
    public static function findIdentity($id)
    {
        return static::findOne(['id' => $id]);
    }
  
}

Accessing the Model

$section = UserToSection::findAll([
        'user_id' => \Yii::$app->user->getId()
      ]);
      print_R($section);
      $section->delete();

Answer 1

I asked myself, I answer myself

$section = UserToSection::deleteAll([
        'user_id' => \Yii::$app->user->getId()
      ]);

Answer 2

findAll returns an array of objects, so
either like this:

$section = UserToSection::findAll(['user_id' => \Yii::$app->user->getId()]);
foreach($section as $one){
$one->delete();
}

either like this:

UserToSection::deleteAll([
        'user_id' => \Yii::$app->user->getId()
      ]);

But keep in mind that the second method does not use events, which means that beforeDelete and afterDelete are bypassed. But 1 is more resource-intensive naturally.
