中的用户已添加到数据库，但无法登录cakePHP2.6.0

有人能给我一个提示为什么我的登录不起作用吗

可以添加用户，还可以创建河豚密码并将中的数据集保存到数据库中，但我无法登录

应用控制器

public $components = array(
                        'DebugKit.Toolbar',
                        'Session',
                        'Paginator' => array(
                            'className' => 'Bancha.BanchaPaginator'),
                        'Auth' => array(
                            'loginRedirect' => array(
                                'controller' => 'posts',
                                'action' => 'index'
                            ),
                            'logoutRedirect' => array(
                                'controller' => 'pages',
                                'action' => 'display',
                                'home'
                            ),
                            'authenticate' => array(
                                'Form' => array(
                                    'passwordHasher' => 'Blowfish'
                                    )
                            ),
                       )
                   );

    public function beforeFilter() {
      $this->Auth->allow('index', 'view');
  }

登录

public function login() {

            if ($this->request->is('post')) {
                if ($this->Auth->login()) {
                    return $this->redirect($this->Auth->redirectUrl());
                }
                $this->Session->setFlash(__('Invalid username or password, try again'));
            }

        }

登录ctp文件

<div class="users form">
<?php echo $this->Session->flash('auth'); ?>
<?php echo $this->Form->create('Benutzer'); ?>
    <fieldset>
        <legend>
            <?php echo __('Please enter your username and password'); ?>
        </legend>
        <?php echo $this->Form->input('username', array('lable' => 'Username', 'type' => 'text'));?>
        <?php echo $this->Form->input('passwort', array('lable' => 'Passwort', 'type' => 'password'));?>
    </fieldset>
<?php echo $this->Form->end(__('Login')); ?>
</div>

问题是，我没有定义“字段”

 'authenticate' => array(
      'Form' => array(
      'fields' => array(
      'username' => 'username', //Default is 'username' in the userModel
      'password' => 'passwort'  //Default is 'password' in the userModel
      )

数据库中密码的字段类型和长度是多少？

 'authenticate' => array(
      'Form' => array(
      'fields' => array(
      'username' => 'username', //Default is 'username' in the userModel
      'password' => 'passwort'  //Default is 'password' in the userModel
      )
