用codeigniter實現php-activerecord的問題

Question

我試圖根據我在上一個stackoverflow帖子中設置的以前的問題來實現php-active記錄， 在codeigniter中用php-activerecord設置火花

好的，所以我將該代碼放入構造函數中，並且我的錯誤消失了。

但現在開始測試該orm是否有效。 我使用以下代碼在models文件夾中創建了一個名為User.php的模型

<?php

class User extends ActiveRecord\Model {


}  

?> 

然后，我繼續在數據庫中創建一個表，用於測試wit-php-activerecord以查看orm是否有效。 所以我決定使用下面的sql代碼將數據庫“ spark”與名為“ users”的表一起使用

CREATE TABLE IF NOT EXISTS `users` (
  `id` int(11) NOT NULL AUTO_INCREMENT,
  `username` varchar(32) NOT NULL,
  `password` varchar(32) NOT NULL,
  PRIMARY KEY (`id`)
) ENGINE=InnoDB  DEFAULT CHARSET=latin1 AUTO_INCREMENT=3 ;

--
-- Dumping data for table `users`
--

INSERT INTO `users` (`id`, `username`, `password`) VALUES
(1, 'shawn', ''),
(2, 'justin', '');

我的database.php也配置為匹配表，如下所示：

$db['default'] = array(
    'dsn'   => '',
    'hostname' => 'localhost',
    'username' => 'root',
    'password' => '',
    'database' => 'spark',
    'dbdriver' => 'mysqli',
    'dbprefix' => '',
    'pconnect' => TRUE,
    'db_debug' => TRUE,
    'cache_on' => FALSE,
    'cachedir' => '',
    'char_set' => 'utf8',
    'dbcollat' => 'utf8_general_ci',
    'swap_pre' => '',
    'autoinit' => TRUE,
    'encrypt' => FALSE,
    'compress' => FALSE,
    'stricton' => FALSE,
    'failover' => array()
);

按日期排序數據庫，因此我打開了welcome.php控制器，並將以下代碼添加到索引方法中，如下所示

public function index()
    {


        $users = User::all();

        echo "<pre>";
        print_r($users);
    }  

我在瀏覽器中運行它，並得到以下錯誤，如下所示

異常消息中清楚地顯示了該問題：

消息：未捕獲的異常“ ActiveRecord \\ DatabaseException”，消息為“ ActiveRecord \\ MysqliAdapter找不到！” 在C：\\ xampp \\ htdocs \\ orm \\ sparks \\ php-activerecord \\ 0.0.2 \\ vendor \\ php-

它正在嘗試為ActiveRecord庫加載mysqli適配器，但找不到它。 該庫未完全安裝（可能缺少可選的mysqli模塊），或者沒有正確設置包含路徑來自動加載其類。
