Using a library class

MY_Model.php

Code:

class MY_Model extends Model
{
    function MY_Model()
    {
        parent::Model();
    }

    function available_to_all_models()
    {
        echo "Hooray!";
    }
}

Then let your models extend MY_Model instead of Model.[/quote]

Thank you, Johan André. Your solution solved my problem.
