cakePHP找不到验证处理程序

我正在为我的cakePHP验证而挣扎

场景:在我的数据库我有一个表"联盟"和一个"联盟"。在"federations"中，联盟之间的连接被存储。"联盟"有愚蠢的标签，比如身份、名字等等。Federations是这样的:

id, request_alliance, accept_alliance, type, requested_at, accepted_at

其中request_alliance和accept_alliance为FK到联盟，类型为1或2。

所以我的模型是这样的:

class Federation extends AppModel
{
  // Bundarten:
  // 1 - NAP
  // 2 - Bund
  public $displayField;
  var $belongsTo = array('Alliance_requesting' => array('className' => 'Alliance', 'foreignKey'   => 'request_alliance'),
                         'Alliance_accepting' => array('className' => 'Alliance', 'foreignKey'   => 'accept_alliance'));

  public $validate = array(
    'request_alliance' => array('required' => true, 'allowEmpty' => false),
    'accept_alliance' => array('required' => true, 'allowEmpty' => false),
    'type' => array('required' => true, 'allowEmpty' => false, 'rule' => array('between', 1, 2))
  );
}  

联盟(由前合伙人创建，我只添加了$hasMany)

类Alliance扩展AppModel{

var $hasMany = array(
  'Federation_requesting' => array('className' => 'Federation', 'foreignKey'   => 'request_alliance', 'dependent' => true),
  'Federation_accepting' => array('className' => 'Federation', 'foreignKey'   => 'accept_alliance', 'dependent' => true)
);
public $validationDomain = 'alliance';
public $validate = array(
  'tag' => array(
    'uniqueTag' => array(
      'rule'    => 'isUnique',
      'message' => 'Alliance tag already in use'),
    'between' => array(
      'rule' => array('between', 2, 15),
      'message' => 'Alliance tag must betwenn %d to %d characters')),
  'name' => array( 
      'rule' => array('between', 3, 30),
      'message' => 'Alliance name must between %d to %d characters'),
  'image_url' => array(
    'rule' => 'url',
    'message' => 'Alliance picture must be a valid URL',
    'allowEmpty' => true),
  'homepage' => array(
    'rule' => 'url',
    'message' => 'Homepage must be a valid URL',
    'allowEmpty' => true));

}

到目前为止，我已经写了一个视图来添加两个联盟之间的新联邦。 的控制器

class FederationsController extends AppController
{
  var $name = 'Federations';
  var $components = array('Message');
  var $uses = array('Alliance', 'Federation');

  // Requesting new federation
  function add()
  {
    if(empty($this->data['Federation'])) {
      $message = __d('federation', "Invalid Request");
      $this->notice($message);
      return $this->redirect(Path::overall_highscore_alliances_path());
    }
    $requesting_alliance_id = $this->data['Federation']['req_alliance_id'];
    $req_alliance           = $this->Alliance->get($requesting_alliance_id);
    if(!$req_alliance) {
      return $this->redirect(Path::overall_highscore_alliances_path());
    }
    if(!$this->Alliance->isCurrentUserDiplomat($req_alliance)) {
      $message = __d('federation', "Only the diplomat is allowed to modify federations.");
      $this->notice($message);
      return $this->redirect(Path::alliance_path($requesting_alliance_id));
    }
    $accepting_alliance_id = $this->data['Federation']['acc_alliance_id'];
    $acc_alliance          = $this->Alliance->get($accepting_alliance_id);
    if(!$acc_alliance) {
      $message = __d('federation', "The target alliance for this federation doesn't exists.");
      $this->notice($message);
      return $this->redirect(Path::alliance_path($requesting_alliance_id));
    }
    $type = $this->data['Federation']['type'];
    $requested_at = time();
    $this->Federation->create();
    $values = array('request_alliance' => $requesting_alliance_id,
      'accept_alliance' => $accepting_alliance_id,
      'type' => $type,
      'requested_at' => $requested_at);
    $saved  = $this->Federation->save($values, true, array('request_alliance', 'accept_alliance', 'type', 'requested_at'));
    $name    = h($acc_alliance['name']);
    $message = $saved ? __d('federation', "Federation with '%s' successfully requested.", $name) : '';
    $this->notice($message);
    $this->errors($this->Federation->validationErrors);
    $this->redirect(Path::alliance_path($requesting_alliance_id));
  }
}

当我尝试添加一个新的联邦时，如果上面的函数被调用，并且在DB中存储了一个具有正确值的新行。但是页面仍然显示以下错误

Could not find validation handler 1 for request_alliance
Could not find validation handler  for request_alliance
Could not find validation handler 1 for accept_alliance
Could not find validation handler  for accept_alliance

我无法想象我的验证没有完成，因为几个小时前我有一个错误，导致空字段，我得到了正确的验证消息，这个字段不能留空。

谁能告诉我我在哪里做的错误，导致这些错误和如何纠正它?

提前感谢!

'request_alliance' => array(
    'required' => true, 
    'allowEmpty' => false
),

'type' => array(
    'required' => true, 
    'allowEmpty' => false, 
    'rule' => array('between', 1, 2)
)

'request_alliance' => array(
    'rule' => 'notEmpty'
)

'request_alliance' => array(
    'rule' => 'notEmpty',
    'required' => true
)
