FuelPHP Forums

Hi guys, I am pretty new to FuelPHP. I have a user model (orm with validation rules).
I have 2 pages: 1. Profile page to update user info (password not required, but can be changed) THIS WORKS.
2. Create a new user page (all info is required just like profile page, but requires a password).
Is there a way to change a model property (at least the validation rule)? Thanks
These are the properties I use in my Model_User:

class Model_User extends Orm\Model
{

 /**
  * Table name
  *
  * @var  string
  */
 protected static $_table_name = 'users';

 /**
  * Primary key
  *
  * @var  array
  */
 protected static $_primary_key = array('id');

 /**
  * Properties
  *
  * @var  array
  */
 protected static $_properties = array(
  'id'             => array('data_type' => 'int'),
  'username'       => array('data_type' => 'varchar', 'validation' => array('required', 'valid_email', 'min_length' => array(3)), 'label' => 'label.username_or_email'),
  'password'       => array('data_type' => 'varchar', 'validation' => array('min_length' => array(3), 'match_field' => array('password2')), 'label' => 'label.new_password'),
  'password2'      => array('data_type' => 'varchar', 'label' => 'label.repeat_new_password'),
  'group'          => array('data_type' => 'int'),
  'email'          => array('data_type' => 'varchar', 'label' => 'email'),
  'firstname'      => array('data_type' => 'varchar', 'validation' => array('required'), 'label' => 'label.firstname'),
  'lastname'       => array('data_type' => 'varchar', 'validation' => array('required'), 'label' => 'label.lastname'),
  'last_login'     => array('data_type' => 'int', 'default' => 0),
  'login_hash'     => array('data_type' => 'varchar', 'default' => ''),
  'profile_fields' => array('data_type' => 'serialize', 'default' => ''),
  'reset_hash'     => array('data_type' => 'varchar', 'default' => ''),
  'created_at'     => array('data_type' => 'time_unix'),
  'updated_at'     => array('data_type' => 'time_unix'),
 );

 /**
  * Used observers
  *
  * @var  array
  */
 protected static $_observers = array(
  'Orm\\Observer_Validation' => array(
   'events' => array('before_save'),
  ),
  'Orm\\Observer_Typing' => array(
   'events' => array('before_save', 'after_save', 'after_load'),
  ),
  'Orm\\Observer_CreatedAt' => array(
   'events' => array('before_insert')
  ),
        'Orm\\Observer_UpdatedAt' => array(
         'events' => array('before_save')
        ),
        'Observer_Password' => array(
         'events' => array('before_save'),
         'fields' => 'password'
        ),
 );
}
