I am working on a Yii2 based project right now. Today when I was testing my application I noticed a very interesting bug in it. I have a Products table with it's model and controllers and views. (These are generated with gii) When I list all the records in the index action it works fine. But here comes the bug. When I click on the edit or view action it alwasy renders the first record in the database. I was var_dump the result of the queries and always returnd the mentiond result. Only when I used createCommand got the proper result.
What do you think guys could be the problem with it?
The controller
<?php
namespace backend\controllers;
use Yii;
use app\models\Termek;
use yii\data\ActiveDataProvider;
use yii\db\Query;
use yii\web\Controller;
use yii\web\NotFoundHttpException;
use yii\filters\VerbFilter;
/**
* TermekController implements the CRUD actions for Termek model.
*/
class TermekController extends Controller
{
/**
* @inheritdoc
*/
public function behaviors()
{
return [
'verbs' => [
'class' => VerbFilter::className(),
'actions' => [
'delete' => ['POST'],
],
],
];
}
/**
* Lists all Termek models.
* @return mixed
*/
public function actionIndex()
{
$dataProvider = new ActiveDataProvider([
'query' => Termek::find(),
]);
return $this->render('index', [
'dataProvider' => $dataProvider,
]);
}
/**
* Displays a single Termek model.
* @param integer $id
* @return mixed
*/
public function actionView($id)
{
$model = $this->findModel($id);
return $this->render('view', [
'model' => $model,
]);
}
/**
* Creates a new Termek model.
* If creation is successful, the browser will be redirected to the 'view' page.
* @return mixed
*/
public function actionCreate()
{
$model = new Termek();
if ($model->load(Yii::$app->request->post()) && $model->save()) {
return $this->redirect(['view', 'id' => $model->id]);
} else {
return $this->render('create', [
'model' => $model,
]);
}
}
/**
* Updates an existing Termek model.
* If update is successful, the browser will be redirected to the 'view' page.
* @param integer $id
* @return mixed
*/
public function actionUpdate($id)
{
$model = $this->findModel($id);
if ($model->load(Yii::$app->request->post()) && $model->save()) {
return $this->redirect(['view', 'id' => $model->id]);
} else {
return $this->render('update', [
'model' => $model,
]);
}
}
/**
* Deletes an existing Termek model.
* If deletion is successful, the browser will be redirected to the 'index' page.
* @param integer $id
* @return mixed
*/
public function actionDelete($id)
{
$this->findModel($id)->delete();
return $this->redirect(['index']);
}
/**
* Finds the Termek model based on its primary key value.
* If the model is not found, a 404 HTTP exception will be thrown.
* @param integer $id
* @return Termek the loaded model
* @throws NotFoundHttpException if the model cannot be found
*/
protected function findModel($id)
{
if (($model = Termek::findOne($id)) !== null) {
return $model;
} else {
throw new NotFoundHttpException('The requested page does not exist.');
}
}
}
The index.php view file
<?php
use yii\helpers\Html;
use yii\grid\GridView;
/* @var $this yii\web\View */
/* @var $dataProvider yii\data\ActiveDataProvider */
$this->title = Yii::t('app', 'Termeks');
$this->params['breadcrumbs'][] = $this->title;
?>
<div class="termek-index">
<h1><?= Html::encode($this->title) ?></h1>
<p>
<?= Html::a(Yii::t('app', 'Create Termek'), ['create'], ['class' => 'btn btn-success']) ?>
</p>
<?= GridView::widget([
'dataProvider' => $dataProvider,
'columns' => [
['class' => 'yii\grid\SerialColumn'],
'id',
'nev',
'szelesseg',
'magassag',
'egyeb:ntext',
// 'ar',
// 'termek_kategoria_id',
// 'torolt',
['class' => 'yii\grid\ActionColumn'],
],
]); ?>
</div>
Part of view.php view file:
<?= DetailView::widget([
'model' => $model,
'attributes' => [
'id',
'nev',
'szelesseg',
'magassag',
'egyeb:ntext',
'ar',
'termek_kategoria_id',
'torolt',
],
]) ?>
Model file:
<?php
namespace app\models;
use Yii;
/**
* This is the model class for table "termek".
*
* @property integer $id
* @property string $nev
* @property double $szelesseg
* @property double $magassag
* @property string $egyeb
* @property string $ar
* @property integer $termek_kategoria_id
* @property string $torolt
*/
class Termek extends \yii\db\ActiveRecord
{
/**
* @inheritdoc
*/
public static function tableName()
{
return 'termek';
}
/**
* @inheritdoc
*/
public function rules()
{
return [
[['nev', 'termek_kategoria_id'], 'required'],
[['szelesseg', 'magassag'], 'number'],
[['egyeb'], 'string'],
[['ar', 'termek_kategoria_id'], 'integer'],
[['torolt'], 'safe'],
[['nev'], 'string', 'max' => 255],
];
}
/**
* @inheritdoc
*/
public function attributeLabels()
{
return [
'id' => Yii::t('app', 'ID'),
'nev' => Yii::t('app', 'Nev'),
'szelesseg' => Yii::t('app', 'Szelesseg'),
'magassag' => Yii::t('app', 'Magassag'),
'egyeb' => Yii::t('app', 'Egyeb'),
'ar' => Yii::t('app', 'Ar'),
'termek_kategoria_id' => Yii::t('app', 'Termek Kategoria ID'),
'torolt' => Yii::t('app', 'Torolt'),
];
}
/**
* @inheritdoc
* @return \app\models\Query\TermekQuery the active query used by this AR class.
*/
public static function find()
{
return new \app\models\Query\TermekQuery(get_called_class());
}
}
Try modify the findModel function using find()->where instead of findOne
protected function findModel($id)
{
var_dump($id);
$model = Termek::find()->where(['id'=> $id])->one();
var_dump($model);
if (($model !== null) {
return $model;
} else {
throw new NotFoundHttpException('The requested page does not exist.');
}
}
I am not sure why but somehow the error solved. I had a function in TermekQuery that was supposed to query all the records that has the deleted field null. I removed it and now works fine.
