Hi,
How can I display the column ‘name’ of a row from a foreign table?
DATABASE SITUATION
Two tables are set:
play_store_category => idcategory (PK) | name
game => idgame (PK) | name | idplaystorecategory (FK)
WHAT I NEED TO DO
I need to display the column ‘name’ from table when I am viewing a game detail. What is happening today is that it simply shows the idcategory (foreign key). I need to get the name from that foreign key.
I tried doing this:
[color="#FF0000"] [
'label' => 'label' => 'PLAY STORE CATEGORY NAME',
'value' => $model->idplaystorecategory->name,
][/color]
But of course it is not working.
HOW MY CODE IS
Generating models,controllers and views by GII CRUD, these are the generated files:
‘GameController.php’:
<?php
namespace app\controllers;
use Yii;
use app\models\Game;
use app\models\GameSearch;
use yii\web\Controller;
use yii\web\NotFoundHttpException;
use yii\filters\VerbFilter;
/**
* GameController implements the CRUD actions for Game model.
*/
class GameController extends Controller
{
public function behaviors()
{
return [
'verbs' => [
'class' => VerbFilter::className(),
'actions' => [
'delete' => ['post'],
],
],
];
}
/**
* Lists all Game models.
* @return mixed
*/
public function actionIndex()
{
$searchModel = new GameSearch();
$dataProvider = $searchModel->search(Yii::$app->request->queryParams);
return $this->render('index', [
'searchModel' => $searchModel,
'dataProvider' => $dataProvider,
]);
}
/**
* Displays a single Game model.
* @param integer $id
* @return mixed
*/
public function actionView($id)
{
return $this->render('view', [
'model' => $this->findModel($id),
]);
}
/**
* Creates a new Game model.
* If creation is successful, the browser will be redirected to the 'view' page.
* @return mixed
*/
public function actionCreate()
{
$model = new Game();
if ($model->load(Yii::$app->request->post()) && $model->save()) {
return $this->redirect(['view', 'id' => $model->idgame]);
} else {
return $this->render('create', [
'model' => $model,
]);
}
}
/**
* Updates an existing Game 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->idgame]);
} else {
return $this->render('update', [
'model' => $model,
]);
}
}
/**
* Deletes an existing Game 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 Game model based on its primary key value.
* If the model is not found, a 404 HTTP exception will be thrown.
* @param integer $id
* @return Game the loaded model
* @throws NotFoundHttpException if the model cannot be found
*/
protected function findModel($id)
{
if (($model = Game::findOne($id)) !== null) {
return $model;
} else {
throw new NotFoundHttpException('The requested page does not exist.');
}
}
}
‘view.php’ (view view for game model):
<?php
use yii\helpers\Html;
use yii\widgets\DetailView;
/* @var $this yii\web\View */
/* @var $model app\models\Game */
$this->title = $model->name;
$this->params['breadcrumbs'][] = ['label' => 'Games', 'url' => ['index']];
$this->params['breadcrumbs'][] = $this->title;
?>
<div class="game-view">
<h1><?= Html::encode($this->title) ?></h1>
<p>
<?= Html::a('Update', ['update', 'id' => $model->idgame], ['class' => 'btn btn-primary']) ?>
<?= Html::a('Delete', ['delete', 'id' => $model->idgame], [
'class' => 'btn btn-danger',
'data' => [
'confirm' => 'Are you sure you want to delete this item?',
'method' => 'post',
],
]) ?>
</p>
<?= DetailView::widget([
'model' => $model,
'attributes' => [
'idgame',
'name',
'idplaystorecategory',
[color="#FF0000"] [
'label' => 'PLAY STORE CATEGORY NAME',
'value' => $model->idplaystorecategory->name,
][/color]
],
]) ?>
</div>
