Calling unknown method: yii\db\ActiveQuery::formName()

Question

I'm trying to learn yii 2.0 by creating a simple form for adding new posts.

Here's the respective method in my SiteController (have also added use app\models\Posts; at the top):

public function actionSave($id=NULL){
    if($id = NULL)
        $model = new Posts;
    else
        $model = $this->loadModel($id);

    if(isset($_POST['Posts'])){
        $model->load($_POST);
        if($model->save()){
            Yii::$app->session->setFlash('success', 'Model has been saved');
            $this->redirect($this->createUrl('site/save', ['id' => $model->id]));
        }else 
            Yii::$app->session->setFlash('error', 'Model could not be saved');
    }
    echo $this->render('save', ['model' => $model]);
}

It renders save view file. Here's that view file:

<?php
    use yii\helpers\Html;
    use yii\widgets\ActiveForm;
?>

<?php $form = ActiveForm::begin(['options' =>   ['class' => 'form-horizontal', 'role' => 'form']]) ?>

<div class="form-group">
    <?php echo $form->field($model, 'title')->textInput(['class' => 'form-control']); ?>
</div>

<div class="form-group">
    <?php echo $form->field($model, 'data')->textArea(['class' => 'form-control']); ?>
</div>

<?php echo Html::submitButton('Submit', ['class' => 'btn btn-primary pull-right']); ?>

<?php ActiveForm::end();

I'm expecting a form, but it's showing an error Calling unknown method: yii\db\ActiveQuery::formName()

What am i doing wrong here?

$form = ActiveForm::begin(); try without any value in begin funciton — Yatin Mistry

I suppose you use the loadModel function, if so, change this line

$model = Posts::find($id);

to this

$model = Posts::find()->where(['id' => $id])->one();

The error occurs because the object returned by loadModel is a ActiveQuery and the ActiveForm expected a ActiveRecord.
