Single model per aplication . - tony.a - 06-25-2020
Is there any drawbacks in using a single model extending basemodel per aplication ,?
Code:
class Basic_Model extends CI_MODEL {
private static $instance;
function __construct() {
// Call the Model constructor
parent::__construct();
}
public static function getInstance()
{
if (!self::$instance instanceof self) {
self::$instance = new self;
}
return self::$instance;
}
}PHP Code:
Class myModel{
var $model ; // base model
public function __construct() {
$this->model = getModelInstance() ; // basic_model singleton
}
function find($params = array()) {
$this->model->db->from(my_table());...
}

You don't need the code you show. Any model loaded using $this->load->model(...) already creates a singleton.
You can use the Auto-loading Resources feature to make the model available all the time for the application.
BTW, you do not need the call to parent::__construct(); in Basic_Model because CI_Model does not have a constructor to call.
