Как называется и выглядит файл Argo_model и есть ли в нем метод getArgo?

class Argo extends MY_Controller {

	public function __constract() {

Ошибка в слово __constract(), нужно писать __construct()

<?php  

class Argo_model extends CI_Model {
	public function __construct() {
		$this->load->database();
	}

	public function getArgo($slug = FALSE, $limit, $type = 1) {

		if ($slug === FALSE) {
			$query = $this->db
				->where('category_id', $type)
				->order_by('add_date', 'desc')
				->limit($limit)
				->get('argo');
			return $query->result_array();
		}
		$query = $this->db->get_where('argo', array('slug' => $slug));
		return $query->row_array();
	}
