CodeIgniter, models, and ORM, how to deal with this?

Question

I\'m starting with CodeIgniter and after several hours diving in Google I\'m a bit confused.

Let\'s try to explain my question with a easy example: I have a table \'car

Answer 1

You probably want something like this:

   class Cars {

    //List all neccessary vars here

    function __construct() {
        //get instance of Codeigniter Object and load database library
        $this->obj =& get_instance();
        $this->obj->load->database();
    }

//You can now list methods like so:
function selectCar($name, $color) {

        $this->obj->db->select('color')->from('car')->where('color', $color);
        $query = $this->obj->db->get();

        switch ($query->num_rows()) {
        case 0:
            return false;
            break;
        default:
            return $query->result();
            break;
        }
    }

Hope that helps!
