cakePHP无法找到验证处理程序

Question

我正在使用cakePHP验证

场景: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 ..联盟是这样的:

id, request_alliance, accept_alliance, type, requested_at, accepted_at

其中request_alliance和accept_alliance对联盟是FK,类型是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$ hasMany)

类联盟扩展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,在两个联盟之间添加一个新的联盟.控制器为此

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));
  }

}

当我尝试添加新联邦时,将调用上述函数,并在DB中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.

任何人都可以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!

Answer 1

没有验证规则定义

从问题中,比较:

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

同

'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'
)

如果要确保所有保存中都存在该字段,请使用所需的密钥

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

无需定义allowEmpty键,因为如果为false,则与notEmpty验证规则相同,如果定义为true,则与notEical相同.
