This is beacuse model is not loaded

I am having a problem getting an error message from the controller that the property Site::$site_model is undefined.

If you dont load model object instance is not created.
[quote author="f0n3man" date="1286486020"]
the php error in the system log states: 'Call to a member function get_records() on a non-object in /path/etc...'.

I can't see where are you loading your model
[quote author="f0n3man" date="1286486020"]
and even have the model loaded in the controller
[/quote]

put this on your constructor:

Code:

$this->load->model('site_model');

Here's the code just run with the same error:

Code:

Controller:

class Welcome extends Controller {

    function Welcome()
    {
        parent::Controller();
        $this->load->database();
        $this->load->helper('url');
        $this->load->helper('form');
        $this->load->model('site_model');
        $this->output->enable_profiler(TRUE);
    }

    function index()
    {
        $data['records'] = $this->site_model->get_records();
        $this->load->view('site_view', $data);
    }

Model:

class Site_model extends CI_Model {

function Site_model()
    {
        parent::CI_Model();
    }
    
    function get_records()
    {
            $q = $this->db->get('data');
        
        if($q->num_rows() > 0) {
            foreach ($q->result() as $row) {
                $data[] = $row;
            }
        return $data;
        }
    }

This worked for me on CI 1.7.2

Controller:

class Welcome extends Controller {

function Welcome()
{
parent::Controller();
$this->load->database();
$this->load->helper('url');
$this->load->helper('form');
$this->load->model('site_model');
$this->output->enable_profiler(TRUE);
}

function index()
{
$data['records'] = $this->site_model->get_records();
$this->load->view('site_view', $data);
}
}

Model:



class Site_model extends Model {

function Site_model()
{
parent::Model();
}

function get_records()
{
$q = $this->db->get('data');

if($q->num_rows() > 0) {
foreach ($q->result() as $row) {
$data[] = $row;
}
return $data;
}
}

}

That tells me there must be a configuration problem. The call to CI_Model has to be there with CI 2 or it throws an error. I guess the only thing to do is start over. Someone else did the install and configuration. I will do it myself this time.

You did not mention that you were using modules or who's module code your using?

Your problem has to do with your modules!

You are correct, I am using modules, and that may be the problem. Like I said, I did not set this up, and so I will be researching this and setting up my own site. I have done some reading and see changes that need to be made to the code. Thanks for all your help, and I'll let you know how it goes.
