Hello I just watched the first/Day1 screencast on Nettuts "CodeIgniter from scracth" And I'm already running into an error I don't understand. Here's a screenshot http://i39.tinypic.com/14mtc0n.jpg
您好，我刚刚在 Nettuts“CodeIgniter from scracth”上观看了第一个/Day1 截屏视频，我已经遇到了一个我不明白的错误。这是截图http://i39.tinypic.com/14mtc0n.jpg
The code in my models\site_model.php is the same as the screencast
我的模型\site_model.php 中的代码与截屏相同
models\site_model.php
class Site_model extends CI_Model {
function getAll() {
$q = $this->db->get('test');
if($q->num_rows() > 0) {
foreach ($q->result() as $row) {
$data[] = $row;
}
return $data;
}
}
And the controller controllers\site.php
和控制器控制器\site.php
class Site extends CI_Controller {
function index(){
$this-> load-> model('site_model');
$data['records'] = $this-> site_model-> getAll();
$this-> load-> view('home', $data);
}
}
And here's my db info incase
这是我的数据库信息 incase
$db['default']['hostname'] = 'localhost';
$db['default']['username'] = 'root';
$db['default']['password'] = '';
$db['default']['database'] = 'ci_series';
(rest is default below)
Thank you
谢谢

You need to load the database first. Codeiginiter won't load it by default for you.
您需要先加载数据库。默认情况下，Codeiginiter 不会为您加载它。
You can either add it to /config/autoload.phplike so
你可以添加它/config/autoload.php喜欢这样
$autoload['libraries'] = array('database');
Or you can load it on demand whenever you want by calling
或者您可以随时通过调用按需加载它
$this->load->database();

Add constructor to you model, if you havenot:
将构造函数添加到您的模型中，如果您还没有：
class Site_model extends CI_Model {
function __construct()
{
parent::__construct();
}
......
}
And: autoload database by changing application/config/autoload.php if you have not autoloaded
并且：如果您还没有自动加载，则通过更改 application/config/autoload.php 自动加载数据库
