__construct()

public function __construct(?string $module_name = null, ?object $caller = null)

// Automatic instantiation by framework (inside a controller)
class Products extends Trongate {
    public function submit() {
        // $this->validation is automatically a Validation instance
        $this->validation->set_rules('name', 'Product Name', 'required|min_length[3]');
        if ($this->validation->run()) {
            // validation passed
        }
