Yii2 multiple table in gridview - php

Question

I have 2 tables with strategy and risk_colors .
I generated Model and CRUD with GII and modified it just a little to get risk_value column in my GridView widget.
Here is my Strategy.php
<?php
namespace backend\models;
use Yii;
use yii\db\ActiveRecord;
use yii\helpers\Url;
use yii\helpers\Html;
use yii\helpers\ArrayHelper;
use yii\db\Expression;
/**
* This is the model class for table "strategy".
*
* #property int $id
* #property string $strategy_title
* #property string $strategy_description
* #property string $strategy_current_money
* #property int $risk_colors_id
*
* #property SelectedStrategies[] $selectedStrategies
* #property RiskColors $riskColors
*/
class Strategy extends \yii\db\ActiveRecord
{
/**
* {#inheritdoc}
*/
public static function tableName()
{
return 'strategy';
}
/**
* {#inheritdoc}
*/
public function rules()
{
return [
[['strategy_title', 'strategy_description', 'strategy_current_money', 'risk_colors_id'], 'required'],
[['strategy_current_money', 'risk_colors_id'], 'integer'],
[['strategy_title'], 'string', 'max' => 255],
[['strategy_description'], 'string', 'max' => 2055],
[['risk_colors_id'], 'exist', 'skipOnError' => true, 'targetClass' => RiskColors::className(), 'targetAttribute' => ['risk_colors_id' => 'id']],
];
}
/**
* {#inheritdoc}
*/
public function attributeLabels()
{
return [
'id' => 'ID',
'strategy_title' => 'Strategy Title',
'strategy_description' => 'Strategy Description',
'strategy_current_money' => 'Strategy Current Money',
'risk_colors_id' => 'Risk Color ID',
'riskValue' => Yii::t('app', 'Risk'),
'colorNumber' => 'Color Number',
];
}
/**
* #return \yii\db\ActiveQuery
*/
public function getSelectedStrategies()
{
return $this->hasMany(SelectedStrategies::className(), ['strategy_id' => 'id']);
}
/**
* #return \yii\db\ActiveQuery
*/
public function getRiskColors()
{
return $this->hasOne(RiskColors::className(), ['id' => 'risk_colors_id']);
}
/**
* #return risk value
*/
public function getRiskValue()
{
return $this->riskColors->risk_value;
}
/**
* #return Get risk value list for dropdown
*/
public function getRiskValueList()
{
$droptions = RiskColors::find()->asArray()->all();
return ArrayHelper::map($droptions, 'id', 'risk_value');
}
/**
* #return Get risk value list for dropdown
*/
public function getColorNumberList()
{
$droptions = RiskColors::find()->asArray()->all();
return ArrayHelper::map($droptions, 'id', 'color_number');
}
}
here is my index.php.
After all i got risk_value column in my GridView, but it looks like i cant sort my table by this field. Here is .
Here is my Search Model
So my question is what should i do to make this field sortable?

Answer 1

In your StrategySearch.php
public function search($params)
{
$query = Strategy::find()->joinWith(['riskColors']);
// add conditions that should always apply here
$dataProvider = new ActiveDataProvider([
'query' => $query,
]);
$dataProvider->sort->attributes['risk_colors_id'] = [
'asc' => ['risk_colors.risk_value' => SORT_ASC],
'desc' => ['risk_colors.risk_value' => SORT_DESC],
];
$this->load($params);
if (!$this->validate()) {
// uncomment the following line if you do not want to return any records when validation fails
// $query->where('0=1');
return $dataProvider;
}
// grid filtering conditions
$query->andFilterWhere([
'id' => $this->id,
'strategy_current_money' => $this->strategy_current_money,
// 'risk_colors_id' => $this->risk_colors_id,
'risk_colors.risk_value' => $this->risk_colors_id
]);
$query->andFilterWhere(['like', 'strategy_title', $this->strategy_title])
->andFilterWhere(['like', 'strategy_description', $this->strategy_description]);
return $dataProvider;
}
