Yii2 several models in one form

Question

How to use multiple models in one form in Yii2?

My case:

In my creation action, I can save to the Agenda_fiscalizacao table , but in the update I get this error when trying to load the form:

Call to a member function formName() on array    

My update:

public function actionUpdate($id)
{
    $model = $this->findModel($id);
    $modelAgenda = AgendaFiscalizacao::findAll(['fiscalizacao_id' => $id]);

    if ($model->load(Yii::$app->request->post()) && Model::loadMultiple($modelAgenda, Yii::$app->request->post())) {
        $valid = $model->validate();
        $valid = $modelAgenda->validade() && $valid;

        if ($valid) {
            $model->save(false);
            $modelAgenda->save(false);
            return $this->redirect(['view', 'id' => $model->id]);
        }
    }

    return $this->render('update', [
        'model' => $model,
        'modelAgenda' => $modelAgenda
    ]);
}

View of my form

<?= $form->field($modelAgenda, 'agenda_id')->checkboxList(Agenda::combo(), ['class' => 'checkbox']) ?>
<?= $form->field($model, 'bioma_id')->dropDownList(Bioma::combo(), ['prompt' => $prompt]) ?>
<?= $form->field($model, 'nome')->textInput(['maxlength' => true]) ?>
<?= $form->field($model, 'tipo_doc')->radioList(['CPF'=>'CPF', 'CNPJ'=>'CNPJ'], ['class' => 'radio']) ?>
<?= $form->field($model, 'n_doc')->widget(MaskedInput::className(), ['mask' => ['999.999.999-99', '99.999.999/9999-99']]) ?>
<?= $form->field($model, 'observacao')->textarea(['rows' => 7]) ?>    

What could be wrong?

EDIT (full error):

Answer 1

1) If you mean working with several models of the same type, the error is in this line:

$valid = $modelAgenda->validade() && $valid;

First, it should be $modelAgenda->validate(), the second $modelAgendacontains an array of models, the method validate()can only be called on one model.

Yii2 validateMultiple():

use yii\base\Model;

...

$valid = Model::validateMultiple($modelAgenda) && $valid;

( ).

, id :

$models = YourModel::find()->index('id')->all();

2) , findAll(), ( ). new create findOne() update . , , $firstModel $secondModel, :

$isSuccess = false;

Yii::$app->db->transaction(function () use ($isSuccess) {
    $areLoaded = $firstModel->load(Yii::$app->request->post()) && $secondModel->load(Yii::$app->request->post();
    $areSaved = $firstModel->save() && $secondModel->save();
    $isSuccess = $areLoaded && $areSaved;
});

if ($isSuccess) {
    return $this->redirect(['view', 'id' => $model->id]);
}

( ).

transactions , :

return [
    'admin' => self::OP_INSERT,
    'api' => self::OP_INSERT | self::OP_UPDATE | self::OP_DELETE,
    // the above is equivalent to the following:
    // 'api' => self::OP_ALL,
];

:

$firstModel->scenario = 'scenarioForTransaction';
$secondModel->scenario = 'scenarioForTransaction';
$areLoaded = $firstModel->load(Yii::$app->request->post()) && $secondModel->load(Yii::$app->request->post();
$areSaved = $firstModel->save() && $secondModel->save();

if ($areLoaded && $areSaved) {
    return $this->redirect(['view', 'id' => $model->id]);
}

Answer 2

public function actionUpdate($id)
{
    $model = $this->findModel($id);
    $modelAgenda = AgendaFiscalizacao::findAll(['fiscalizacao_id' => $id]);

    if ($model->load(Yii::$app->request->post()) && $modelAgenda->load(Yii::$app->request->post()) && Model::validateMultiple([$model, $modelAgenda])) {

            $model->save(false);
            $modelAgenda->save(false);
            return $this->redirect(['view', 'id' => $model->id]);

    }

    return $this->render('update', [
        'model' => $model,
        'modelAgenda' => $modelAgenda
    ]);
}
