get values from table with foreign key - php

Question

Hi I have 2 tables and models for them. First of them is
User
and second
News
I want to take user id from table News and draw her name and surname. There is printscreen of table News:
I am trying to use the function:
public function getUrUser()
{
$q= News::find()->where(['urUser_Id' =>'Id'])->one();
$RoyalUserData=User::findOne($q);
//$RoyalUserData= User::find()->where(['Id' => $q])->one();
return $RoyalUserData->Name;
}
But this doesnt work. Only when I prescribe to q value 3 for egzample then it work. I know that is the wrong code in my first line of my function probably. I know that is easy but I am a beginner and I've fought with the code for about 1 hour. Can anyone help me?
In my view I use this:
<?=$model->getUrUser();?>
And I use this in ListView.
My controller:
public function actionIndex()
{
$model = new NewsForm();
$searchModel = new NewsSearch();
$dataProvider = $searchModel->search(Yii::$app->request->queryParams);
$dataProvider->setSort(['defaultOrder' => ['Id'=>SORT_DESC]]);
if ($model->load(Yii::$app->request->post()) && $model->validate()) {
$model->saveNews();
return $this->redirect(['/content/news']);
} else {
return $this->render('index', [
'model' => $model,
'searchModel' => $searchModel,
'dataProvider' => $dataProvider,
]);
}
}
My index where i use _item:
echo ListView::widget( [
'dataProvider' => $dataProvider,
'itemView' => '_item',
], $options = ['class' => 'sorter'] ); ?>
And content of _item
<?php
use yii\helpers\Html;
?>
Treść Newsa:
<?=$model->Text;?> <br>
Autor:
<?=Yii::$app->user->identity->Name?>
<?=Yii::$app->user->identity->Surname?> <br>
Status Newsa:
<?=$model->cnNewsContentType_Id;?> <br>
<?= Html::a('Update', ['update', 'id' => $model->Id], ['class' => 'btn btn-primary']) ?>
<?= Html::a('Delete', ['delete', 'id' => $model->Id], [
'class' => 'btn btn-danger',
'data' => [
'confirm' => 'Are you sure you want to delete this item?',
'method' => 'post',
],
]) ?><br><br><br>

Answer 1

The News::find()->where(['urUser_Id' =>'Id'])->one() return a model not a field
then you must get the id field by the model this way
public function getUrUser($id)
{
// you already have the news model so don't need retrieve it
// it's enough pass the urUser_Id by $id
$RoyalUserData=User::findOne($id);
return $RoyalUserData->Name;
}
Then if you want show the ($RoyalUserData) Name in _item
<?=$model->getUrUser($model->urUser_Id);?>

Answer 2

public function getUrUser()
{
$q = News::find()->where(['urUser_Id' =>'Id'])->one();
return $q->user->name;
}
In user model you should create relation:
class News extends ActiveRecord
{
// ...
public function getUser()
{
return $this->hasOne(User::className(), ['id' => 'user_id']);
}
}
