<?php
class News_model extends CI_Model {

    public function __construct()

            }

            $query = $this->db->get_where('news', array('slug' => $slug));
            return $query->row_array();

贴上controller

<?php
class News extends CI_controller{

        public function __contruct()

        }

        public function index()
        {
                $data['news'] = $this->news_model->get_news();
                $data['title']='News archive';

                $this->load->view('templates/header',$data);

从你的错误信息看  明明是没有找到model, 首先你的model是否有放在子目录中 ,放在子目录要加上目录名,其次试试model取个别名再用 我也刚学.勿喷

注意大小写，一个是 news_model 一个是 News_model
