How to save a model in json in yii2?


How to save a model in json in yii2?

To fix the issue you can do thanks for all answers. I wanted to save all model as a json or string in DB and then retrive it and use as a model again. so I've solved this problem by serialize()
code :
$book = \backend\models\Book::find()->all();
$str = serialize($book);
$object = unserialize($str);
$ID = $object[0]['ID'];

seems to work fine My mistake was obviously stupid, but here it is. I've created method beforeSave in my model and haven't filled it and totally forgot about it's existence. So, 'cause it's not returned true - validate() cannot pass properly. Sorry for wasted time.

Does that help Check out Model::toArray(): http://www.yiiframework.com/doc-2.0/yii-base-arrayabletrait.html#toArray%28%29-detail
Something like this should automatically do what you want:
code :
class Marker {
    public function fields()
    {
        $fields = parent::fields();
        $fields[] = 'user';

        return $fields;
    }
}

$marker->toArray();

Hope that helps $model->save()->rawSql call can not return null, it must throw an exception that you are trying to access property of non-object. $model->save() returns boolean value - either query executed successfully or not.
If $model->getErrors() returns empty array and query was not executed at all I'm pretty sure that something is wrong with model event handlers, especially beforeSave(), check it, it should not return false. Also check attached behaviors event handlers.
code :
$values = $this->getDirtyAttributes($attributes);
if (empty($values)) {
    foreach ($this->getPrimaryKey(true) as $key => $value) {
        $values[$key] = $value;
    }
}
$db = static::getDb();
$command = $db->createCommand()->insert($this->tableName(), $values);
if (!$command->execute()) {
    return false;
}
if ($model->validate()) {
    $model->save();
}

will help you It could be a problem related with your validation rules.
Try, as a test, to save the model without any validation in this way:
code :
$model->save(false);

will help you I will try to explain why you should almost always use a Form model to validate your data, providing some cases:
1) Doing
code :
if( $model->load( \Yii::$app->request->post() ) &&  $model->save() )
$user = Yii::$app->user;
if ($user->can('retailer')) {
    $model = new RetailerAgreementForm();
}
else {
    $model = new MerchantAgreementForm();
}
if ( $model->load( \Yii::$app->request->post() ) && $model->save() ) {
....
}
public function rules()
{
    return [
        ['body', 'string', 'max' => 300],
        ['price', 'integer', 'max'=> 1000],
    ];
}
