Kohana 3.2 - ORM Update field which have been modifed by admin - php

Question

Im back to professional programming after 5 year late, so i have learn from beginning ;)
So i chose Kohana framework for my first framework i try to bulid first application now and i have a small problem, lets begin.
I use Kohana ORM and Auth module, as you know default Auth module user table have default fields (username, password, lastlogin) i try to extend User by:
Creating new table (user_additionals)
Creating new model (User_Additional)
Model look like this: http://pastie.org/private/412jflfoifyqs46uaxmga - Nothing special. Everything will be okay, i like easy reference like this: $user->additional->firstname etc.
At the moment i have bulid admin panel (admin can edit every user) and... every field. I have 10 fields like firstname, lastname, birthdate presented as form (filled form - placeholder loaded by template assign) and here is my small problem:
I want to give admin possibility to edit one from much fields, if admin need to edit user signature or something else - he edit one field from a lot fields available and click "Submit" it's easy - one form have been updated.
But, if i try use something like this:
$edit = ORM::Factory('User_Additional')->values($_POST); I get validation Exception (which be catched but, here are validation error - model required all fields to be !empty... (By validation rules)
I use temporary solution, but im a perfectionist and i want to create good code from begining, so here you can find my code: http://pastie.org/private/axtwxbt66gtvcwiv97hvlq
My solution start at line 29 (link above).
So my question is:
*How to make exceptions from Validation in cases like this?? *
*How make exceptions from validation for example for action /admin/edituser/ is it possible? *
*How do i can do my model code better? Thanks for any suggestions which can help me *
Thanks!

Validation will only run on "non-empty" fields, unless you specify the "not_empty" rule.
So basically, you could do the following: (when you need to enforce the "non emptiness" of a field)
class Model_User_Additional extends ORM
{
protected $foreign_key_suffix = 'user_id';
protected $_primary_key = 'user_id';
public function enforce_rules(array $fields)
{
$validation = Validation::factory($this->_object);
foreach ($fields as $field)
{
$validation->rule($field, 'not_empty');
}
return $validation;
}
public function rules()
{
/* Removed all not_empty */
return array(
/* 'user_id' => array(
array('not_empty'),
), */
'firstname' => array(
array('text'),
),
'lastname' => array(
array('text'),
),
'birthdate' => array(
array('date'),
),
'postprice' => array(
array('decimal'),
),
'articleprice' => array(
array('decimal'),
),
'phonenumber' => array(
array('phone'),
),
/* 'active' => array(
array('not_empty'),
), */
/* 'lastupdate' => array(
array('not_empty'),
), */
'info' => array(
array('text'),
),
);
}
public function edit_user($values, $expected, $extra_validation = NULL)
{
return $this->values($values, $expected)->update($extra_validation);
}
}
the usage would be:
$user = ORM::factory('User_Additional');
$user->values(array('field' => 'value'))->create($user->enforce_rules(array('user_id')));
/* and the same for updating */
$user->set('info', $_POST['info'])->update($user->enforce_rules(array('info')));
