How to see where the error is when adding an entry in yii2?

Question

Yii

Classic controller

public function actionCreate()
    {
        $model = new Post;

        if ($model->load(Yii::$app->request->post()) && $model->save()) {
            return $this->redirect(['view', 'id' => $model->id]);
        } else {
            return $this->render('create', [
                'model' => $model,
            ]);
        }
    }

when adding an entry, I remain on the same page, i.e. the model is not saved, and no errors are displayed. How to correctly make validation errors or what else could be displayed on the screen?
I understand that there is $model->getErrors() but why is it not written in the controller by default?

It also should not be registered in the controler. Try adding yii2x.com/display-form-errors-errorsummary <?= $form->errorSummary($model)
right after creating the form . ?>
