codeigniter加载一个具有带参数的构造函数的模型

Question

My model class:

<?php class Permissions extends CI_Model {

    private $userID   = '';
    private $permissions = '';

    function __construct($userID)
    {
        // Call the Model constructor
        parent::__construct();

        $this->userID = $userID;
        ....
    }
    function __construct()
    {.....}
?>

and I want to load this model with a parameter, apparently I could not do it. Without a parameter I can load parameterless constructor by this way:

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

My first question: is loading a model with a parameter nonsense? Second one: if it is doable, how can I do that? Thanks in advance.

You could take a look at this forum thread: http://codeigniter.com/forums/viewthread/115681/

But I can't see why would you want to give a userid as a parameter in a way for permission checking? Guessing you use sessions to save userdata, write the userid in the session and call this in the Model with $this->session->userdata('user_id').

Happy coding!
