Phalcon：顯示花哨錯誤消息而不是標準異常

使用InnoDb與foreignkey在數據庫中設置。在Phalcon也設置虛擬鍵。在刪除記錄時得到低於錯誤從phalcon由於Foreign Key設置和還有子表中的數據。Phalcon：顯示花哨錯誤消息而不是標準異常

My Objective is to display fancy error message to user when this error displayed.

顯示錯誤：

SQLSTATE[23000]: Integrity constraint violation: 1451 Cannot delete or update a parent row: a foreign key constraint fails (`invoice`.`invoice`, CONSTRAINT `Invoice.CustomerId` FOREIGN KEY (`CustomerId`) REFERENCES `customer` (`Id`)) 
#0 [internal function]: PDOStatement->execute() 
#1 [internal function]: Phalcon\Db\Adapter\Pdo->executePrepared(Object(PDOStatement), Array, Array) 
#2 [internal function]: Phalcon\Db\Adapter\Pdo->execute('DELETE FROM `in...', Array, Array) 
#3 [internal function]: Phalcon\Db\Adapter->delete(Array, '`Id` = ?', Array, Array) 
#4 C:\wamp\www\invoice\app\controllers\CustomerController.php(140): Phalcon\Mvc\Model->delete() 
#5 [internal function]: CustomerController->deleteAction('3') 
#6 [internal function]: Phalcon\Dispatcher->callActionMethod(Object(CustomerController), 'deleteAction', Array) 
#7 [internal function]: Phalcon\Dispatcher->_dispatch() 
#8 [internal function]: Phalcon\Dispatcher->dispatch() 
#9 C:\wamp\www\invoice\public\index.php(42): Phalcon\Mvc\Application->handle() 
#10 {main}

花式錯誤消息，我想顯示用戶：

The customer cannot be deleted because other invoices are using it

這是我的模型看起來像：

<?php 
    class Customer extends \Phalcon\Mvc\Model 
    { 
     public $id; 
     public $name; 
     public $street; 
     public $city; 
     public $country; 
     public $postalCode; 
     public $phone; 
     public $mobile; 
     public $fax; 
     public $email; 
     public $web; 
     public function initialize() 
     { 
      $this->setSchema("invoice"); 
      $this->setSource("customer"); 
      $this->hasMany(
       'Id', 
       'Invoice', 
       'Id', 
       [ 
        'alias' => 'Invoice', 
        'foreignKey' => [ 
         'message' => 'The customer cannot be deleted because other invoices are using it', 
        ] 
       ] 
      ); 
     } 
     public static function find($parameters = null) 
     { 
      return parent::find($parameters); 
     } 
     public static function findFirst($parameters = null) 
     { 
      return parent::findFirst($parameters); 
     } 
     public function getSource() 
     { 
      return 'customer'; 
     } 

    } 
    ?>

完整代碼可在github以備參考。

僅供參考：模型和控制器是使用'php-devtools'創建的，我相信'關係中不會有任何問題' –

抓住異常，然後處理它以適合您。 http://php.net/manual/en/language.exceptions.php – yogur

你寫錯了關係。

屬於關聯參數：

首先是在當前模型屬性（列），第二個是相關類，第三是在相關模型柱

的hasMany/hasOne參數：

首先是當前模型中的列，第二個是相關類，第三個是相關模型中的列

所以你的情況應該是一流的客戶：

$this->hasMany(
    'id', 
    'Invoice', 
    'customerId', 
    [ 
     'alias' => 'Invoices', // it's has many relations so better Invoices alias 
     'foreignKey' => [ 
      'message' => 'The customer cannot be deleted because other invoices are using it', 
     ] 
    ] 
);

在發票類：

$this->belongsTo('customerId', '\Customer', 'id', ['alias' => 'Customer']);

不知道這是否會單獨雖然解決您的問題。

強制更新我的模型後使用'php-devtools'它看起來像工作文件.... –
