joinWith multiple tables yii 2 - php

Question

Hi is possible to join multiple table based on a column in yii 2? Right now I am using the concept of joinWith
Take a look at my code:
ActiveCurriculum.php
This is where I am joining the tables
public static function Addblock($group, $clientid){
$subjects = ActiveCurriculum::find()
->select(['scstock.*', 'schead.*', 'glhead.*', 'glfees.*'])
->joinWith('schead')
->joinWith('glhead')
->joinWith('glfees')
->where([
'scstock.sectiongroup' => $group
])
->asArray()
->all();
}
And these are the relations that I set:
Scstock
<?php
namespace app\models;
use Yii;
use yii\base\NotSupportedException;
use yii\behaviors\TimestampBehavior;
use yii\db\ActiveRecord;
use yii\web\IdentityInterface;
class Scstock extends ActiveRecord{
public static function tableName()
{
return '{{%scstock}}';
}
public function getSchead(){
return $this->hasOne(Schead::className(), ['TrNo' => 'TrNo']);
}
public function getGlhead(){
return $this->hasOne(Glhead::className(), ['TrNo' => 'TrNo']);
}
public function getGlfees(){
return $this->hasOne(Glfees::className(), ['TrNo' => 'TrNo']);
}
}?>
Schead
<?php
namespace app\models;
use Yii;
use yii\base\NotSupportedException;
use yii\behaviors\TimestampBehavior;
use yii\db\ActiveRecord;
use yii\web\IdentityInterface;
class Schead extends ActiveRecord{
public static function tableName()
{
return '{{%schead}}';
}
public function getScstock(){
return $this->hasOne(ActiveCurriculum::className(), ['TrNo' => 'TrNo']);
}
public function getGlhead(){
return $this->hasOne(Glhead::className(), ['TrNo' => 'TrNo']);
}
public function getGlfees(){
return $this->hasOne(Glfees::className(), ['TrNo' => 'TrNo']);
}
}?>
Glhead
<?php
namespace app\models;
use Yii;
use yii\base\NotSupportedException;
use yii\behaviors\TimestampBehavior;
use yii\db\ActiveRecord;
use yii\web\IdentityInterface;
class Glhead extends ActiveRecord{
public static function tableName()
{
return '{{%glhead}}';
}
public function getScstock(){
return $this->hasOne(ActiveCurriculum::className(), ['TrNo' => 'TrNo']);
}
public function getSchead(){
return $this->hasOne(Schead::className(), ['TrNo' => 'TrNo']);
}
public function getGlfees(){
return $this->hasOne(Glfees::className(), ['TrNo' => 'TrNo']);
}
}?>
Glfees
<?php
namespace app\models;
use Yii;
use yii\base\NotSupportedException;
use yii\behaviors\TimestampBehavior;
use yii\db\ActiveRecord;
use yii\web\IdentityInterface;
class Glfees extends ActiveRecord{
public static function tableName()
{
return '{{%glfees}}';
}
public function getGlhead(){
return $this->hasOne(Glhead::className(), ['TrNo' => 'TrNo']);
}
public function getSchead(){
return $this->hasOne(Schead::className(), ['TrNo' => 'TrNo']);
}
public function getScstock(){
return $this->hasOne(ActiveCurriculum::className(), ['TrNo' => 'TrNo']);
}
}?>
But I am getting this error when the query executes
Invalid Parameter – yii\base\InvalidParamException
app\models\ActiveCurriculum has no relation named "glhead".
↵
Caused by: Unknown Method – yii\base\UnknownMethodException
Calling unknown method: app\models\ActiveCurriculum::getglhead()
in C:\xampp\htdocs\enrollment\vendor\yiisoft\yii2\base\Component.php at line 285
Am I doing something wrong with the relations or is it something else? Help would be greatly appreaciated. Thank you.

All these relations:
->joinWith('schead')
->joinWith('glhead')
->joinWith('glfees')
must be declared in ActiveCurriculum class. Consult relations in Yii2 documentation.
