Yii2 | GridView table, communication between models does not work - php

Question

The connection between the modules does not work, and because of this, the data in the table is not displayed. I can not understand why
Code in the controller
public function actionIndex()
{
$searchModel = new SuggestedNewsSearch();
$dataProvider = $searchModel->getAllNews(Yii::$app->request->queryParams);
return $this->render('index', [
'dataProvider' => $dataProvider,
'searchModel' => $searchModel
]);
}
code in suggestedNewsSearch.php
class SuggestedNewsSearch extends SuggestedNews
{
public function getAllNews($params)
{
$query = $this::find();
$dataProvider = new ActiveDataProvider([
'query' => $query,
]);
if ($this->validate() AND !($this->load($params))) {
return $dataProvider;
}
if (!empty($this->getAttribute('title'))) {
$query->andFilterWhere(['LIKE', 'title', $this->getAttribute('title')]);
}
if (!empty($this->getAttribute('category'))) {
$query->andFilterWhere(['LIKE', 'category', $this->getAttribute('category')]);
}
if (!empty($this->getAttribute('status'))) {
switch (mb_strtolower($this->getAttribute('status'))) {
case $this::APPROVED:
$status = $this::ACTIVE_STATUS;
break;
case $this::NOT_APPROVED:
$status = $this::DEACTIVATED_STATUS;
break;
}
$query->andFilterWhere(['=', 'status', $status]);
}
return $dataProvider;
}
}
code on SuggestedNews.php
class SuggestedNews extends \yii\db\ActiveRecord
{
CONST ACTIVE_NEWS = 1;
CONST ACTIVE_STATUS = 1;
CONST DEACTIVATED_STATUS = 0;
CONST APPROVED = 'одобренно';
CONST NOT_APPROVED = 'не одобренно';
/**
* {#inheritdoc}

public static function tableName()
{
return 'suggested_news';
}
/**
* {#inheritdoc}
*/
public function rules()
{
return [
[['news'], 'string'],
[['category', 'status'], 'integer'],
[['date'], 'safe'],
[['title', 'news_source'], 'string', 'max' => 255],
[['category'], 'exist', 'skipOnError' => true, 'targetClass' => Category::className(), 'targetAttribute' => ['category' => 'id']],
];
}
/**

public function attributeLabels()
{
return [
'id' => 'ID',
'title' => 'Title',
'news' => 'News',
'category' => 'Category',
'status' => 'Status',
'date' => 'Date',
'news_source' => 'News Source',
];
}
/**
* #return \yii\db\ActiveQuery
*/
public function getCategory()
{
return $this->hasOne(Category::className(), ['id' => 'category']);
}
public function deleteNewsById($id)
{
$customer = $this::findOne($id);
if ($customer->delete()) return true;
else return false;
}
public function getNewsByIdWithCategory($id){
return $this::find()->where(['id' => $id])->with('category')->one();
}
}
code on Category.php
class Category extends \yii\db\ActiveRecord
{
CONST STATUS_CATEGORY_OFF = 0;
CONST STATUS_CATEGORY_ON = 1;
CONST NEW_CATEGORY_INTEGER = 01;
CONST NEW_CATEGORY_NAME = 'New Category';
/**
* {#inheritdoc}
*/
public static function tableName()
{
return 'category';
}
/**
* {#inheritdoc}
*/
public function rules()
{
return [
[['name', 'status_category'], 'required'],
[['status_category'], 'integer'],
[['name'], 'string', 'max' => 255],
];
}
/**
* {#inheritdoc}
*/
public function attributeLabels()
{
return [
'id' => 'ID',
'name' => 'Name',
'status_category' => 'Status Category',
];
}
/**
* #return \yii\db\ActiveQuery
*/
public function getSuggestedNews()
{
return $this->hasMany(SuggestedNews::className(), ['category' => 'id']);
}
public function getAllCategories(){
return $this::find()->where(['status_category' => $this::STATUS_CATEGORY_ON])->all();
}
}
my index.php file(view)
<?php echo GridView::widget([
'dataProvider' => $dataProvider,
'filterModel' => $searchModel,
'columns' => [
['class' => 'yii\grid\SerialColumn'],
'id',
[
'attribute' => 'title',
'format' => 'text',
'label' => 'title',
'filter' => true,
],
[
'attribute' => 'category.Category',
'format' => 'text',
'label' => 'Category',
],
[
'attribute' => 'status',
'filter' => true,
'value' => function($model) {
if($model->status == 1){
return $model::APPROVED;
}else{
return $model::NOT_APPROVED;
}
}
],
'date',
[
'class' => 'yii\grid\ActionColumn',
],
],
]);
?>

Answer 1

You field name and relation are the same, so You have to change Category relation name like this:
/**
* #return \yii\db\ActiveQuery
*/
public function getCategory1()
{
return $this->hasOne(Category::className(), ['id' => 'category']);
}
//Gridview
//...
[
'attribute' => 'category',
'label' => 'Category',
'value' => function($model){
return $model->category1->name;
}
],
//...
//or
//...
[
'attribute' => 'category1.name',
'format' => 'text',
'label' => 'Category',
],
Hope it will helps.
