Design
------
The design approach involves creating the data structure to store the serialized array configurations with tags as variables that will be replaced at runtime. The rules/validators for validating the widget configuration, will also be stored serialized in a rules column. While running the widget at runtime, the rules will be validated dynamically using the yii\base\DynamicModel.

### 1. Data Structure
Create a table `tbl_widget_config` in your database with the following minimum columns. Create a model called `WidgetConfig` for this table through gii.

~~~
[...]
// Retrieve the configuration
public function runWidget($configId) {
$dbWidget = WidgetConfig::findOne($configId)->asArray(); $widgetConfig = \yii\base\DynamicModel::validateData( static::parseTags($dbWidget['->config']), static::parseTags($dbWidget['->rules']) ); // To run the widget call below  $class = $dbWidget['->class_name'];
 
    $class::widget($widgetConfig->getAttributes()); } ```
