How can I get the value from method in my model? - view

Question

I have some trouble displaying my result from a method in my model. this is the method:
/**
* #return \yii\db\ActiveQuery
*/
public function getSchoolFee()
{
return $this->hasOne(SibuSchool::className(), ['school_fee_id' => 'school_fee_id']);
}
/**
* #return \yii\db\ActiveQuery
*/
public function getScholarshipFee()
{
return $this->hasOne(SibuScholarship::className(),['scholarship_id'=>'scholarship_id']);
}
/**
* #return \yii\db\ActiveQuery
*/
public function getDiscountFee()
{
$scholarship= $this->getScholarshipFee();
$school= $this->getSchoolFee();
$data= new SibuPayment();
$data->total_payment=$school->amount-($scholarship->school_discount*$school->amount);
return $data;
}
i want to display the result from getDiscountFee method. I use this code on my View:
<?php echo $this->render('_search3', ['model' => $searchModel]); ?>
<?=
GridView::widget([
'dataProvider' => $dataProvider,
// 'filterModel' => $searchModel,
'columns' => [
[
// 'filterModel'=>'dataProviderSearch',
'attribute' => 'Nama',
'value' => 'virtual.student_name'
],
[
'attribute' => 'Uang Sekolah',
'value' => 'discountFee.total_payment'
],
[
'attribute' => 'Uang Kantin',
'value' => 'canteenFee.total_amount'
],
[
'attribute' => 'Uang Asrama',
'value' => 'dormitoryFee.amount'
],
[
'attribute' => 'Uang Perpustakaan',
'value' => 'libraryFee.amount'
],
[
'attribute' => 'Uang Les',
'value' => 'courseFee.amount'
],
[
'attribute' => 'Adm. Bank',
'value' => 'administration'
],
[
'attribute' => 'status',
'value' => function ($model) {
if ($model->scholarship_id == 0) {
return 'Tanpa Beasiswa';
} else if ($model->scholarship_id == 1) {
return 'Beasiswa Ekonomi Kategori A 100%';
} else if ($model->scholarship_id == 2) {
return 'Beasiswa Ekonomi Kategori B 50%';
} else if ($model->scholarship_id == 3) {
return 'Beasiswa Prestasi Kategori 50%';
} else if ($model->scholarship_id == 4) {
return 'Beasiswa Prestasi Kategori 25%';
} else {
return 'Beasiswa Prestasi Kategori 10%';
}
},
],
//'payment_class',
[
'attribute' => 'payment_class',
'value' => function ($model) {
if ($model->payment_class == 0) {
return 'Tanpa Golongan';
} else if ($model->payment_class == 1) {
return 'Golongan 1';
} else if ($model->payment_class == 2) {
return 'Golongan 2';
} else if ($model->payment_class == 3) {
return 'Golongan 3';
} else if ($model->payment_class == 4) {
return 'Golongan 4';
}
},
],
[
'attribute' => 'Total',
'value' => 'total_payment'
],
['class' => 'yii\grid\ActionColumn',
'template' => '{update_r}{del}',
'buttons' => [
'update_r' => function ($url, $model) {
return Html::a('<span class="glyphicon glyphicon-pencil"></span>', $url, [
'title' => Yii::t('yii', 'View_r'),
]);
},
'del' => function ($url, $model) {
return Html::a('<span class="glyphicon glyphicon-trash"></span>', $url, [
'title' => Yii::t('yii', 'Del'),
]);
},
]
],
],
]);
?>
it works fine if i display this:
[
'attribute' => 'Uang Sekolah',
'value' => 'scholarshipFee.school_discount'
],
and this:
[
'attribute' => 'Uang Sekolah',
'value' => 'schoolFee.amount'
],
can anybody help me? if you need anything feel free to ask.

Answer 1

[
'attribute' => 'Uang Sekolah',
'value' => 'discountFee.total_payment'
],
discountFee is a function of a model, it will never work until you put there the model too. You can just do a
[
'attribute' => 'Uang Sekolah',
'value' => function ($model) {
return $model->getDiscountFee()->total_payment;
}
},
],
