php - Codeigniter - undefined property $grocery_crud -


very new codeingiter , trying implement grocery crud following tutorial http://www.grocerycrud.com/documentation/create-crud-codeigniter-tutorial.

have done in following code (by way, i'm autoloading database library , url helper). 

<?php  class management extends ci_controller {   public function construct() {     parent::__construct();     $this->load->library('grocery_crud'); }  public function index () {     echo "<h1>just work!</h1>";     die(); }   public function property () {     $this->grocery_crud->set_table('property');     $output = $this->grocery_crud->render();       echo "<pre>";     print_r($output);     echo "</pre>";     die(); }   /** public function view($page = 'management_page') {     if ( ! file_exists('application/views/pages/'.$page.'.php'))     {         // whoops, don't have page that!         show_404();     }        $data['title'] = ucfirst($page); // capitalize first letter        $this->load->view('templates/header', $data);                    $this->load->view('pages/'.$page, $data);     $this->load->view('templates/footer', $data);  } **/ }

however, when load page @ [base ]/management/property following error:

severity: notice  message: undefined property: management::$grocery_crud  filename: controllers/management.php  line number: 21

can help?

have resolved now, not 100% sure i've moved on quite bit in code , db structure, think not having 'property' table in db.
