我需要修改理论验证的默认错误消息。怎么样我可以这样做吗?
CrazyJoe是正确的,在某种程度上:没有一些艰苦的工作就不可能:-(
但是,如果您努力搜索,可能会找到方法[[;;-]
使用Doctrine 1.1,您可以对模型类进行扩展Doctrine_Record
。该类定义了此方法:/**
* Get the record error stack as a human readable string.
* Useful for outputting errors to user via web browser
*
* @return string $message
*/
public function getErrorStackAsString()
{
$errorStack = $this->getErrorStack();
if (count($errorStack)) {
$message = sprintf("Validation failed in class %s\n\n", get_class($this));
$message .= " " . count($errorStack) . " field" . (count($errorStack) > 1 ? 's' : null) . " had validation error" . (count($errorStack) > 1 ? 's' : null) . ":\n\n";
foreach ($errorStack as $field => $errors) {
$message .= " * " . count($errors) . " validator" . (count($errors) > 1 ? 's' : null) . " failed on $field (" . implode(", ", $errors) . ")\n";
}
return $message;
} else {
return false;
}
}
这是生成消息的方法;如您所见,它是全自动的,并且根本不是可配置的[[:-(
尽管如此,多亏了OOP,我们可以在Model类中重载该方法...
但是,为了更干净一点,我会:[创建一个新类-例如My_Doctrine_Record
,扩展了Doctrine_Record
My_Doctrine_Record
类。My_Doctrine_Record::getErrorStackAsString
方法当然可以依靠我们的模型类的方法来帮助生成消息,并为每个模型类进行特殊定制。这是一个可行的例子;远非完美,但它可能会指导您获得想要的
;;-)
首先,初始化:
require_once '/usr/share/php/Doctrine/lib/Doctrine.php';
spl_autoload_register(array('Doctrine', 'autoload'));
$manager = Doctrine_Manager::getInstance();
$manager->setAttribute(Doctrine::ATTR_VALIDATE, Doctrine::VALIDATE_ALL);
$conn = Doctrine_Manager::connection('mysql://test:123456@localhost/test1');
我猜您的应用程序中已经有类似的东西...
接下来,我们新的My_Doctrine_Record
类:
class My_Doctrine_Record extends Doctrine_Record { public function getErrorStackAsString() { $errorStack = $this->getErrorStack(); if (count($errorStack)) { $message = sprintf("BAD DATA in class %s :\n", get_class($this)); foreach ($errorStack as $field => $errors) { $messageForField = $this->_getValidationFailed($field, $errors); if ($messageForField === null) { // No custom message for this case => we use the default one. $message .= " * " . count($errors) . " validator" . (count($errors) > 1 ? 's' : null) . " failed on $field (" . implode(", ", $errors) . ")\n"; } else { $message .= " * " . $messageForField; } } return $message; } else { return false; } } protected function _getValidationFailed($field, $errors) { return null; } }
[您会注意到getErrorStackAsString
方法是受教义所提供的方法启发的-这似乎很正常,我想说^^
另一件事要注意:它定义并调用_
getValidationFailed
方法
null
(如果我们要使用默认行为)>_getValidationFailed
方法,以自定义内容class Test extends My_Doctrine_Record
{
protected function _getValidationFailed($field, $errors) {
switch ($field) {
case 'name':
return "You entered wrong data from 'name' field.\n Errors are for '"
. implode("', '", $errors) . "'\n";
break;
// other fields ?
default:
return null;
}
}
public function setTableDefinition()
{
$this->setTableName('test');
$this->hasColumn('id', 'integer', 4, array(
'type' => 'integer',
'length' => 4,
'unsigned' => 0,
'primary' => true,
'autoincrement' => true,
));
$this->hasColumn('name', 'string', 32, array(
'type' => 'string',
'length' => 32,
'fixed' => false,
'notnull' => true,
'email' => true,
));
$this->hasColumn('value', 'string', 128, array(
'type' => 'string',
'length' => 128,
'fixed' => false,
'notnull' => true,
'htmlcolor' => true,
));
$this->hasColumn('date_field', 'integer', 4, array(
'type' => 'timestamp',
'notnull' => true,
));
}
}
它扩展了My_Doctrine_Record
,并定义了一个_getValidationFailed
方法,该方法处理模型的name
字段上的验证错误。
现在,假设我这样做是为了加载记录:
$test = Doctrine::getTable('Test')->find(1); var_dump($test->toArray());
让我们尝试修改它,设置“坏”值:
$test->name = (string)time(); $test->value = 'glop'; try { $test->save(); } catch (Doctrine_Validator_Exception $e) { echo '<pre>'; echo $e->getMessage(); echo '</pre>'; die; }
name
和value
字段都不正确...因此,我们将遍历验证方法,并生成此错误消息:
BAD DATA in class Test : * You entered wrong data from 'name' field. Errors are for 'email' * 1 validator failed on value (htmlcolor)
您可以看到“
name
”的消息已被定制,而“value
”的消息来自默认的教义。
因此,总结一下:不容易,但可行;-)
并且,现在,由您决定使用它作为解决问题的精确方法的指南:-)
我认为,这将需要更多的编码。但是您离真正的交易还很遥远!玩得开心!
