[eluser]quasiperfect[/eluser]
i tried to use gas but i get a error maybe someone can help
the error is Fatal error: Class 'User' not found

i use latest gas,codeigniter from git
and @wiredesignz hmvc extension

i even tried to load user model but no luck i get Fatal error: Call to undefined method Gas::load_model()

in my gas config i have

Code:

$config['models_path'] = array(APPPATH.'models', APPPATH.'modules');
$config['models_suffix'] = '_gas';
$config['autoload_models'] = TRUE;
$config['cache_request'] = TRUE;
$config['auto_create_models'] = FALSE;
$config['auto_create_tables'] = TRUE;

i have models/user_gas.php

Code:

class User extends Gas
{
public $table = 'users';
public $primary_key = 'id';
public $relations = array(
  'has_many' => array('comment' => array()),
);

function _init()
{
  $this->_fields = array(
   'id' => Gas::field('auto[11]'),
   'username' => Gas::field('char[6,15]'),
   'password' => Gas::field('char[6,15]'),
   'email'    => Gas::field('email'),
   'created_at' => Gas::field('datetime'),
   'updated_at' => Gas::field('datetime'),
   'deleted_at' => Gas::field('datetime'),
   'delted' => Gas::field('int[1]'),
  );
  $this->_unique_fields = array('email', 'username');
  $this->_ts_fields = array('updated_at');
}
}

and i call gas like this

Code:

$data = array(
   'username' => 'myusername',
   'email'    => '[email protected]',
   'password' => md5('[email protected]'),
   'created_at' => date("Y-m-d H:i:s"),
   'updated_at' => date("Y-m-d H:i:s"),
   'deleted_at' => '',
   'delted' => 0,
  );
  $new_user = new User;
  $new_user->fill($data, TRUE);
  if ( ! $new_user->save(TRUE))
  {
         echo $new_user->errors('<p class="error">', '</p>');
         echo 'The raw errors were : ';
         print_r($new_user->errors);
  }
  else
  {
         echo 'New user successfully created. And her id is '.$new_user->last_id();
  }
