我是 Code Igniter 和 GroceryCRUD 的新手。在基本安装和验证之后，我创建了数据库表并开始遵循位于此处的新手教程。

Fatal error: Uncaught exception Exception with message The table name does not exist.
Please check you database and try again. in /Library/WebServer/Documents/application/libraries/Grocery_CRUD.php:4349

我得到的表不存在，当我修改 main.php 以显示表列表时
echo "<pre>";
print_r($this->db->list_tables());
die();
我得到一个空数组。所以我认为我配置的 MySQL 用户可能有问题，尽管数据库连接成功，但不知何故数据库没有被选中（或者我会在初始化过程的早期爆炸）。
我的配置
Mac OSX 10.7.5
数据库.php
$active_group = 'default';
$active_record = TRUE;
$db['default']['hostname'] = 'localhost';
$db['default']['username'] = 'cruduser';
$db['default']['password'] = 'foo45bar';
$db['default']['database'] = 'crud';
$db['default']['dbdriver'] = 'mysql';
$db['default']['dbprefix'] = '';
$db['default']['pconnect'] = TRUE;
$db['default']['db_debug'] = FALSE;
$db['default']['cache_on'] = FALSE;
$db['default']['cachedir'] = '';
$db['default']['char_set'] = 'utf8';
$db['default']['dbcollat'] = 'utf8_general_ci';
$db['default']['swap_pre'] = '';
$db['default']['autoinit'] = TRUE;
$db['default']['stricton'] = FALSE;
$this->db->list_tables()) 的结果；在 main.php
欢迎来到 Codeigniter 的世界
