Invalid Configuration Error in Yii2

Yii 2.0 General Discussions

Hi, I am using Yii2 basic and also using dynamic form widget. The scenario is One Pastor has many Short term goals and each short term goals can have Missional and Spiritual Personal goals. So I am using the nested dynamic form. Here I have implemented actionCreate() which is functioning well. But in actionUpdate() It gives me error as below

# Invalid Configuration – [yii\base\InvalidConfigException](http://www.yiiframework.com/doc-2.0/yii-base-invalidconfigexception.html)

## The 'model' property must be set and must extend from '\yii\base\Model'.

Following is my actionUpdate() code.

public function actionUpdate($id)
    {

		$model = $this->findModel($id);
		$modelsShortTerm=$model->shorttermgoals;
		$modelsShortTermMissional = [];
        $oldShortTermMissional = [];

        if (!empty($modelsShortTerm)) {
            foreach ($modelsShortTerm as $indexShortTerm => $modelShortTerm) {
                $missional = $modelShortTerm->shorttermmissionalgoals;
                $modelsShortTerm[$indexShortTerm] = $missional;
                $oldShortTermMissional = ArrayHelper::merge(ArrayHelper::index($missional, 'ShortTermMissionalGoalId'), $oldShortTermMissional);
            }
        }

		if ($model->load(Yii::$app->request->post())) {

			$modelsShortTermMissional = [];


		$oldIDs = ArrayHelper::map($modelsShortTerm, 'ShortTermGoalsId', 'ShortTermGoalsId');

				$modelsShortTerm = Modelshortterm::createMultiple(Shorttermgoals::classname(), $modelsShortTerm);
        
				Modelshortterm::loadMultiple($modelsShortTerm, Yii::$app->request->post());

				$deletedIDs = array_diff($oldIDs, array_filter(ArrayHelper::map($modelsShortTerm, 'ShortTermGoalsId', 'ShortTermGoalsId')));


				
				$valid = $model->validate();
            	$valid = Modelshortterm::validateMultiple($modelsShortTerm) && $valid;


				$missionalId = [];
				if (isset($_POST['Shorttermmissionalgoals'][0][0])) {
                foreach ($_POST['Shorttermmissionalgoals'] as $indexShortTerm => $missional) {
                    $missionalId = ArrayHelper::merge($missionalId, array_filter(ArrayHelper::getColumn($missional, 'ShortTermMissionalGoalId')));
                    foreach ($missional as $indexMissional => $missional1) {
                        $data['Shorttermmissionalgoals'] = $missional1;

                        $modelShortTermMissional->load($data);

			$oldMissionalId = ArrayHelper::getColumn($oldShortTermMissional, 'ShortTermMissionalGoalId');

            //return $this->redirect(['view', 'id' => $model->GroupId]);
        
		}else {

                'model' => $model,

            ]);
        }
    }

What should I do?

Hi @SoftwareAccount;

you must extend your class model from \yii\base\model or child class extended, example \yii\db\ActiveRecord

My Pastor model is extended by \yii\db\ActiveRecord

class Pastor extends \yii\db\ActiveRecord
{
}

Also I am usnig Modelshortterm class which extends \yii\base\Model

<?php

namespace app\models;

use Yii;
use yii\helpers\ArrayHelper;

class Modelshortterm extends \yii\base\Model
{
    /**
     * Creates and populates a set of models.
     *
     * @param string $modelClass
     * @param array $multipleModels
     * @return array
     */
    public static function createMultiple($modelClass, $multipleModels = [])
    {
        $model    = new $modelClass;
        $formName = $model->formName();
        $post     = Yii::$app->request->post($formName);
        $models   = [];

        if (! empty($multipleModels)) {
            $keys = array_keys(ArrayHelper::map($multipleModels, 'ShortTermGoalsId', 'ShortTermGoalsId'));
            $multipleModels = array_combine($keys, $multipleModels);
        }

        if ($post && is_array($post)) {
            foreach ($post as $i => $item) {
                if (isset($item['ShortTermGoalsId']) && !empty($item['ShortTermGoalsId']) && isset($multipleModels[$item['ShortTermGoalsId']])) {
                    $models[] = $multipleModels[$item['ShortTermGoalsId']];
                } else {
                    $models[] = new $modelClass;
                }
            }
        }


        unset($model, $formName, $post);

        return $models;
    }
}
