Question

i’m using codeigniter for my project and i have this class model which i call Genesis which looks like this:

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

    function get() {
        return 'human soul';
    }
}

and i have another model, stored in the same directory, which extends Genesis_model

class Human_model extends Genesis_model {
    function __construct() {
        parent::__construct();
    }

    function get_human() {
        return $this->get();
    }
}

Human_model is used by Human controller

class Human extends CI_Controller {     
    function __construct(){
        parent::__construct();
        $this->load->model('human_model');
    }       

    function get_human() {
        $data['human'] = $this->human_model->get_human();
        $this->load->view('human/human_interface', $data);
    }
}

if i execute the code, it will produce an error which point to return $this->get(). it reads “Fatal error: Class ‘Genesis_model’ not found in …\application\models\human_model.php on line 2”.

i use this method because nearly all my models shared almost identical structure. I gather the similar functionality in Genesis while the other models serve only as data suppliers unique to the tables they represent. it works well in my asp.net (vb.net) but i don’t how to do it in codeigniter.

is there a way for Human_model to inherit Genesis_model. i don’t think i’m allowed to use include(‘genesis_model.php’). i don’t know if it works either.

thanks in advance.

Put the file genesis_model.php in the core directory
