An error occurred
An error occurred

我的error.phtml是

<h1>An error occurred</h1>
  <h2><?PHP echo $this->message ?></h2>
  <?PHP if (isset($this->exception)): ?>

  <h3>Exception information:</h3>
  <p>
      <b>Message:</b> <?PHP echo $this->exception->getMessage() ?>
  </p>

  <h3>Stack trace:</h3>
  <pre><?PHP echo $this->exception->getTraceAsString() ?>
  </pre>

  <h3>Request Parameters:</h3>
  <pre><?PHP echo $this->escape(var_export($this->request->getParams(),true)) ?>
  </pre>

  <?PHP endif ?>

这就是我在IndexAction中所拥有的

$this->view->title="My Places";
$this->view->headTitle($this->view->title);
$Places=new Places();
echo "<pre>";var_dump($Places->fetchAll(null,'date_created DESC',4)); echo "</pre>";

和我的模块文件ID

class Places extends Zend_Db_Table
{
    protected $_name='places';
    public function fetchLatest($count=10)
    {
        return $this->fetchAll(null,$count);
    }

}

**编辑**
ErrorController是

<?PHP

class ErrorController extends Zend_Controller_Action
{

    public function errorAction()
    {
        $errors = $this->_getParam('error_handler');

        if (!$errors || !$errors instanceof ArrayObject) {
            $this->view->message = 'You have reached the error page';
            return;
        }

        switch ($errors->type) {
            case Zend_Controller_Plugin_ErrorHandler::EXCEPTION_NO_ROUTE:
            case Zend_Controller_Plugin_ErrorHandler::EXCEPTION_NO_CONTROLLER:
            case Zend_Controller_Plugin_ErrorHandler::EXCEPTION_NO_ACTION:
                // 404 error -- controller or action not found
                $this->getResponse()->setHttpResponseCode(404);
                $priority = Zend_Log::NOTICE;
                $this->view->message = 'Page not found';
                break;
            default:
                // application error
                $this->getResponse()->setHttpResponseCode(500);
                $priority = Zend_Log::CRIT;
                $this->view->message = 'Application error';
                break;
        }

        // Log exception,if logger available
        if ($log = $this->getLog()) {
            $log->log($this->view->message,$priority,$errors->exception);
            $log->log('Request Parameters',$errors->request->getParams());
        }

        // conditionally display exceptions
        if ($this->getInvokeArg('displayExceptions') == true) {
            $this->view->exception = $errors->exception;
        }

        $this->view->request   = $errors->request;
    }

    public function getLog()
    {
        $bootstrap = $this->getInvokeArg('bootstrap');
        if (!$bootstrap->hasResource('Log')) {
            return false;
        }
        $log = $bootstrap->getResource('Log');

        return $log;
    }


}

我怎么知道导致这个错误的原因？ (我怎么能看到完整的错误日志？)
谢谢
