I'm trying to use an ActiveDataProvider as the source for my ActiveDataForm. However I am unable to access the information. Not from within the view or the controller. How ever the diseaseList + ListView is working.
I can't seem to figure out where I went wrong. Even when I get a disease like so:
$disease = new Disease();
$disease = Disease::find()->where(['id'=>1]);
I cannot access the data. Only when I initiate a NEW disease in the controller I can get the ActiveForm to work properly.
Controller:
public function actionIndex($id = 1)
{
$disease = new ActiveDataProvider([
'query' => Disease::find()
->where(['id'=>$id]),
'pagination' => [
'pageSize' => 1,
]
]);
$diseaseList = new ActiveDataProvider([
'query' => Disease::find()->orderBy('LOWER(name)'),
'pagination' => [
'pageSize' => 20,
]
]);
return $this->render('index', ['disease' => $disease, 'diseaseList' => $diseaseList]);
}
In my view:
<?php
echo ListView::widget([
'dataProvider' => $diseaseList,
'itemView' => function($diseaseList, $key, $index, $widget)
{
return
Html::a($diseaseList->name,
Url::toRoute(['disease/index', 'id' => $diseaseList->primaryKey]));
}
]);
?>
<?php
$form = ActiveForm::begin([
'id' => 'disease-form-vertical'
]);
?>
<?= $form->field($disease, 'name') ?>
<?= $form->field($disease, 'description') ?>
<?= $form->field($disease, 'transmission') ?>
<?= $form->field($disease, 'actions') ?>
<?= $form->field($disease, 'report') ?>
<?= $form->field($disease, 'exclusion') ?>
<?= $form->field($disease, 'notes') ?>
<div class="form-group">
<?= Html::submitButton('Login', ['class' => 'btn btn-primary']) ?>
<?= Html::resetButton('Reset', ['class' => 'btn btn-default']) ?>
</div>
<?php ActiveForm::end(); ?>
Here is the error I'm receiving.
There is something wrong here, which is:
$disease = Disease::find()->where(['id'=>1]);
That should be:
$disease = Disease::find()->where(['id'=>1])->one();
To know why you get this error: You are passing ActiveQuery
to your ActiveForm
by $disease = Disease::find()->where(['id'=>1])
which is wrong. ActiveForm
does not accept ActiveQuery
.
