Codeigniter的奇怪问题（模型问题）

Question

I have set up a local copy of CodeIgniter and another copy on a linux machine. After installing both copies with my application, the local copy is running just fine but the linux version is showing the following error code:

Unable to locate the model you have specified: User_model

I have searched all day for the answer to this. I have tried to change the spelling on the name of the model, file name, everything that I can think of. What could i be missing that would display that error?

Thanks guys

Here is a copy of my code:

(user_model.php)

 <?php

class User_model extends CI_Model {
    public function __construct(){
        parent::__construct();
    }

    function runTest(){
        return "Testing";
    }
}
?>

(welcome.php)

class Welcome extends CI_Controller {
public function __construct(){
    parent::__construct();
}
public function index()
{
    $this->load->model('User_Model');
    $data['testing'] = $this->user1234->runTest();
    $this->load->view('welcome_message', $data);
}

}

Answer 1

It is because of case sensitivity. First of all you should keep all file names in small letters ( user_model.php ) and then use that name in controller ( $this->load->model('user_model'); ) .

It must work.
