错误CodeIgniter中使用多个数据库

我试图在CI中实现多个数据库。我的代码是在这里：错误CodeIgniter中使用多个数据库

//database.php 
$active_group = "default"; 
$active_record = TRUE; 

$db['default']['hostname'] = "localhost"; 
$db['default']['username'] = "root"; 
$db['default']['password'] = "root"; 
$db['default']['database'] = "ravelex"; 
$db['default']['dbdriver'] = "mysql"; 
$db['default']['dbprefix'] = "rvx_"; 
$db['default']['pconnect'] = TRUE; 
$db['default']['db_debug'] = TRUE; 
$db['default']['cache_on'] = FALSE; 
$db['default']['cachedir'] = ""; 
$db['default']['char_set'] = "utf8"; 
$db['default']['dbcollat'] = "utf8_general_ci"; 

$db['smf']['hostname'] = "localhost"; 
$db['smf']['username'] = "root"; 
$db['smf']['password'] = "root"; 
$db['smf']['database'] = "smf"; 
$db['smf']['dbdriver'] = "mysql"; 
$db['smf']['dbprefix'] = "smf_"; 
$db['smf']['pconnect'] = TRUE; 
$db['smf']['db_debug'] = TRUE; 
$db['smf']['cache_on'] = FALSE; 
$db['smf']['cachedir'] = ""; 
$db['smf']['char_set'] = "utf8"; 
$db['smf']['dbcollat'] = "utf8_general_ci";

该模型是

//user_model.php 
class user_model extends Model { 
    private $ravelex_db; 
    function user_model() { 
     parent::Model(); 
     $this->ravelex_db = $this->load->database('default', TRUE); 
    } 

    function find_all() { 
     print_r($this->ravelex_db); 
     $q = $this->ravelex_db->get('users'); 
     return $q->result(); 
    } 
} 

//smf_user_model.php 
class smf_user_model extends Model { 
    private $smf_db; 

    function smf_user_model() { 
     parent::Model(); 
     $this->smf_db = $this->load->database('smf', TRUE); 
    } 

    function find_all() { 
     $q = $this->smf_db->get('members'); 
     return $q->result(); 
    } 
}

控制器测试仪

class mutipledb extends Controller { 

    function mutipledb() { 
     parent::Controller(); 
     $this->load->database(); 
     $this->load->model('user_model'); 
     $this->load->model('smf_user_model'); 
    } 

    function index() { 
     print_r($this->user_model->find_all()); 
     print_r($this->smf_user_model->find_all()); 
    } 
}

有一些错误时，第一个数据库使用第二数据库名称。但它仍然使用它的前缀。

的错误是

A Database Error Occurred 
Error Number: 1146 
Table 'smf.rvx_users' doesn't exist 
SELECT * FROM (`rvx_users`)

如果我只是加载一个模型......，它的工作原理。 class mutipledb extends Controller {

function mutipledb() { 
     parent::Controller(); 
     $this->load->database(); 
     //$this->load->model('user_model'); 
     $this->load->model('smf_user_model'); 
    } 

    function index() { 
     //print_r($this->user_model->find_all()); 
     print_r($this->smf_user_model->find_all()); 
    } 
}

为什么会发生这种情况？请帮助我

重复http://stackoverflow.com/questions/2124993/mutiple-database-in-codeigniter的。请不要重复您的问题，您可以编辑您现有的问题以提供更多详细信息。 – Groo 2010-01-25 09:18:23

我发现这篇文章比其他文章更有帮助。谢谢阿迪。 – 2012-01-29 04:53:28

我找到了解决方案。

对于数据库配置或数据库配置之一，将pconnect设置为FALSE。

$db['default']['pconnect'] = FALSE; 
$db['smf']['pconnect'] = FALSE;

$db['default']['pconnect'] = TRUE; 
$db['smf']['pconnect'] = FALSE; 
//and vice versa
