Yii2 ошибка сохранения модели

Previously, I was not using $model->save() function for inserting or updating any data. I was simply using createCommand() to execute query and it was working successfully. But, my team members asked me to avoid createCommand() and use $model->save();

Now, I started cleaning my code and problem is $model->save(); not working for me. I don’t know where i did mistake.

UsersController.php (Controller)

<?php
namespace appmodulesuserscontrollers;
use Yii;
use yiiwebNotFoundHttpException;
use yiifiltersVerbFilter;
use yiiswiftmailerMailer;
use yiifiltersAccessControl;
use yiiwebResponse;
use yiiwidgetsActiveForm;
use appmodulesusersmodelsUsers;
use appcontrollersCommonController;

class UsersController extends CommonController 
{
    .
    .

    public function actionRegister() {
    $model = new Users();

        // For Ajax Email Exist Validation
   if(Yii::$app->request->isAjax && $model->load(Yii::$app->request->post())){
     Yii::$app->response->format = Response::FORMAT_JSON;
     return ActiveForm::validate($model);
   } 

   else if ($model->load(Yii::$app->request->post())) {
      $post = Yii::$app->request->post('Users');
      $CheckExistingUser = $model->findOne(['email' => $post['email']]);

      // Ok. Email Doesn't Exist
      if(!$CheckExistingUser) {

        $auth_key = $model->getConfirmationLink();
        $password = md5($post['password']);
        $registration_ip = Yii::$app->getRequest()->getUserIP();
        $created_at = date('Y-m-d h:i:s');

        $model->auth_key = $auth_key;
        $model->password = $password;
        $model->registration_ip = $registration_ip;
        $model->created_at = $created_at;

        if($model->save()) {
          print_r("asd");
        }

      }

    } 
    }
    .
    .
}

Everything OK in this except $model->save(); Not printing ‘asd’ as i echoed it.

And, if i write

else if ($model->load(Yii::$app->request->post() && $model->validate()) {

}

It’s not entering to this if condition.

And, if i write

if($model->save(false)) {
    print_r("asd");
}

It insert NULL to all columns and print ‘asd’

Any help is appreciable. Please Help me.

Есть код такого вида:

$model=new Products();
$model=$model->findOne(['id'=>1]);
$model->name="Новое название";
$model->save();

То есть нужно перезаписать поле но save не работает и подсвечивается в IDE как «not found in class null|static»
Если убрать строчку $model=$model->findOne([‘id’=>1]);
то создает новый товар, а как этот отредактировать то ? Хоть убейте не вижу тут ошибки.

class Products extends yiidbActiveRecord
{
    /**
     * @inheritdoc
     */
    public static function tableName()
    {
        return 'products';
    }

    /**
     * @inheritdoc
     */
    public function rules()
    {
        return [
            [['name', 'url', 'price','quantity','category_id','options_id','mark','model'], 'required'],
            [['price'], 'number'],
            [['full_desc'], 'string'],
            [['category_id','options_id','quantity','status'], 'integer'],
            [['name', 'url'], 'string', 'max' => 50],
            [['short_desc'], 'string', 'max' => 250]
        ];
    }
}

P.S я знаю что кроме name есть еще поля и они обозначены как required я их тоже указываю при редактировании просто не писал в примере чтобы не усложнять читабельность

Не могу понять почему не сохраняются данные в БД
При вызове метода save(false) у заполненной модели, создаются пустые поля в БД (хотя вроде как все правила для полей прописал):
Уж сижу несколько часов.

Контроллер (точнее один метод из него)

public function actionAddDriver(){

        $modelDriver = new Driver();

        $postRequest = Yii::$app->request->post();

        $isValidate = false;
        if($modelDriver->load($postRequest)){
            if($modelDriver->validate()){
                var_dump($modelDriver, true);
                $modelDriver->save(false);
                $isValidate = true;
            }
        }
        return $this->render('addDriver',['modelDriver'=>$modelDriver, 'isValidate'=>$isValidate]);
    }
 

Модель

<?php
namespace appmodels;

use yiidbActiveRecord;

class Driver extends ActiveRecord{

    public $name;
    public $lastname;
    public $patronymic;
    public $percent;

    public static function tableName(){
        return 'drivers';
    }

    public function getOrder(){
        return $this->hasMany(Order::className(),['driver_id'=>'id']);
    }

    public function attributeLabels(){
        return [
            'name'=>'Имя таксиста',
            'lastname'=>'Фамилия таксиста',
            'patronymic'=>'Отчество таксиста',
            'percent' => 'Процент'
        ];
    }

    public function rules(){
        return [
            [['name','percent'],'required'],
            [['name','lastname','patronymic'], 'string', 'length'=>[3,50]],
            ['percent','number'],
        ];
    }
}
 

Вид:

<?php
use yiiwidgetsActiveForm;
use yiihelpersHtml;
?>
    <?php if($isValidate):?>
        <div class="alert alert-success alert-dismissable">
            <button type="button" class="close" data-dismiss="alert" aria-hidden="true">&times;</button>
            Запись добавлена!

        <div class="alert alert-warning alert-dismissable">
            <button type="button" class="close" data-dismiss="alert" aria-hidden="true">&times;</button>
            ОШИБКА добавления!
        </div>
    <?php endif?>



<?php
$form = ActiveForm::begin(['id'=>'form-edit-driver','method'=>'post']);
    echo $form->field($modelDriver,'name')->textInput();
    echo $form->field($modelDriver,'lastname')->textInput();
    echo $form->field($modelDriver,'patronymic')->textInput();
    echo $form->field($modelDriver,'percent')->textInput();
    echo Html::submitButton('Добавить',['class'=>'btn btn-success']);
ActiveForm::end();

Даже не знаю с чем может быть проблема) знаю что из-за rules может не добавлять в БД, но вроде верно написал в правилах модели.
