مشکل در نمایش اطلاعات جدول بانک

این فایل های BlogModal هست :

<?php
class BlogModal extends CI_Model { public function __construct() { parent::__construct(); // Your own constructor code } //$this->load->database(); function getAllPost() { $this->db->get('user'); }
}
?>

و این هم کدهای فایل Blog.php که Controller هست :

<?php
defined('BASEPATH') OR exit('No direct script access allowed');
class Blog extends CI_Controller { function index() { //$this->load->view('BlogView'); $this->load->model('BlogModal'); $posts = $this->BlogModal->getAllPost(); print_r($posts); }
}

در خروجی چیزی نمایش داده نمی شود.
تشکر

الآن یک return قبل از دستور :

$this->db->get('user');

قرار دادم . اطلاعات نمایش داده شد اما طالاعات جدول بانک نیست!
