Yii2 create or update user profile - yii2

Question

In my basic app, I have a User model and a UserForm model that stores and update the users in the database. Now, I got problem when updating the user profile. It feedbacks 'Successful update!' even though the new data won't save.
My table:
Table name: User
Attributes: id, fname, mname, lname, address, username, auth_key, password_hash, password_reset_token, email, status, created_at, updated_at
My Model:
class UserForm extends Model
{
public $fname;
public $mname;
public $lname;
public $address;
public $username;
public $email;
public $password_hash;
/**
* #inheritdoc
*/
public function rules()
{
return [
['fname', 'required'],
['fname', 'trim'],
['mname', 'trim'],
['lname', 'required'],
['lname', 'trim'],
['address', 'required'],
['address', 'trim'],
['address', 'string', 'max' => 255],
['username', 'trim'],
['username', 'required'],
['username', 'unique', 'targetClass' => '\app\models\User', 'message' => 'This username has already been taken.'],
['username', 'string', 'min' => 4, 'max' => 255],
['email', 'trim'],
['email', 'required'],
['email', 'email'],
['email', 'string', 'max' => 255],
['email', 'unique', 'targetClass' => '\app\models\User', 'message' => 'This email address has already been taken.'],
['password_hash', 'required', 'on' => 'insert'],
['password_hash', 'string', 'min' => 8],
];
}
public function beforeSave($insert) {
if ($insert) {
$this->setPassword($this->password_hash);
} else {
if (!empty($this->password_hash)) {
$this->setPassword($this->password_hash);
} else {
$this->password_hash = (string) $this->getOldAttribute('password_hash');
}
}
return parent::beforeSave($insert);
}
}
My controller:
public function actionUpdate($id)
{
$model = $this->findModel($id);
$model->setAttribute('password_hash', null);
if ($model->load(Yii::$app->request->post()) && $model->save()) {
Yii::$app->session->setFlash('success', Yii::t('app', 'Successful update!'));
return $this->redirect(['overview']);
} else {
return $this->render('update', [
'model' => $model,
]);
}
}
protected function findModel($id) {
if (($model = User::findOne($id)) !== null) {
return $model;
} else {
throw new NotFoundHttpException('The requested page does not exist.');
}
}
My view.php
<?= $form->field($model, 'fname')->textInput(['autofocus' => true])->label('First Name') ?>
<?= $form->field($model, 'mname')->textInput()->label('Middle Name') ?>
<?= $form->field($model, 'lname')->textInput()->label('Last Name') ?>
<?= $form->field($model, 'address')->textInput() ?>
<?= $form->field($model, 'username')->textInput() ?>
<?= $form->field($model, 'email') ?>
<?= $form->field($model, 'password_hash')->passwordInput(['placeholder' => Yii::t('app', 'Password'), 'value' => ''])->label(false) ?>
<div class="form-group">
<?= Html::submitButton($model->isNewRecord ? Yii::t('app', 'Create') : Yii::t('app', 'Update'), ['class' => $model->isNewRecord ? 'btn btn-success' : 'btn btn-primary']) ?>
</div>
<?php ActiveForm::end(); ?>
Some of the steps are from here: yii2 user CRUD create or update with password

Answer 1

Your UserForm is never used. Your findModel() returns User, so all validation and saving is handled by User model - I guess it does not have any validation rules, so $model->load() does not load anything.
You may try to extend your form model from active record model:
class UserForm extends User
And use it in findModel() or create separate method for returning form model:
protected function findFormModel($id) {
if (($model = UserForm::findOne($id)) !== null) {
return $model;
} else {
throw new NotFoundHttpException('The requested page does not exist.');
}
}
Then use this method in your update action. Don't forget to remove old properties from UserForm - they're unnecessary and may break attributes behavior.
