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

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