kohana - 在传递给视图之前截断db结果ORM

Question

For example,

I have an ORM set up like below.

$test = new Model_Test();
$test_result = $test->find_all();

foreach ($test_result as $tmp) :

    // i would like to truncate the the $tmp->name and put it back to $test ORM like

    $test->name = truncate($tmp->name, 20); 

endforeach;

I would like to truncate the ORM result before passing to view. How can we do that?

Help appreciated!

thanks,

This is actually quite easy thanks to the get() method in Kohana's ORM module. You can have a script as simple as

class Model_Test extends ORM
{
    protected $_stringLength = 20;

    public function get($column)
    {
        $value = parent::get($column);

        if (is_string($value))
            return substr($value, 0, $this->_stringLength);
        else
            return $value;
    }
}
