Question

我正在使用cakePHP验证

方案：在我的数据库中，我有一个表“联盟”和一个“联盟”。在“联盟”中，存储联盟之间的联系。 “联盟”有像id，name等愚蠢的cols。联合会是这样的：

id, request_alliance, accept_alliance, type, requested_at, accepted_at

其中request_alliance和accept_alliance对联盟是FK，类型为1或2。

所以我的模型看起来像这样：

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）

类联盟扩展了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，在两个联盟之间添加一个新的联盟。这个控制器

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));
  }

}

当我尝试添加新的联合时，将调用上述函数，并在DB内部使用正确的值存储新行。但该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，该字段不能留空。

有谁能告诉我在哪里犯了导致这些错误的错误以及如何纠正错误？

提前致谢！

没有验证规则定义

从问题中，比较：

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

使用

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

在第一种情况下没有规则，如果您将验证规则定义为数组，则规则是必需的密钥。

使用notEmpty验证规则

从定义的验证规则来看，似乎存在误解。您可能需要notEmpty验证规则：

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

如果您想确保所有保存中都有该字段，请使用the required key

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

没有必要定义allowEmpty key，因为如果为false则与notEmpty验证规则相同，如果定义为true则与notical不相同。
