Cakephp 2.0使用电子邮件而不是用户名验证

Question

在我看来,我有:

<?php
echo $this->Form->create('User', array("controller" => "Users", "action" => "login", "method" => "post"));
echo $this->Form->input('User.email', array("label" => false));
echo $this->Form->input('User.password', array("label" => false, 'class' => 'password-input'));
echo $this->Form->end(); ?>

在我的AppController中:

public $components = array(
        'Session',
        'Auth'
    );

    function beforeFilter(){
        $this->Auth->fields = array(
            'username' => 'email',
            'password' => 'password'
        );
    }

在我的UsersController中:

function beforeFilter(){
        $this->Auth->allow('sign_up', 'login', 'logout', 'forgot_password');
        return parent::beforeFilter();
    }
public function login() {
        if ($this->Auth->login()) {
            $this->Session->setFlash(__('Successfully logged in'), 'default', array('class' => 'success'));
            $this->redirect($this->Auth->redirect());
        } else {
            if (!empty($this->request->data)) {
                $this->Session->setFlash(__('Username or password is incorrect'), 'default', array('class' => 'notice'));
            }
        }
    }

但登录不起作用,我错过了什么？

谢谢.

我相信问题是:

function beforeFilter(){
    $this->Auth->fields = array(
        'username' => 'email',
        'password' => 'password'
    );
}

这就是CakePHP 1.3中指定自定义登录字段的方式.CakePHP 2.0要求您在中指定这些字段public $components = array(...);.该1.3 API显示验证有$字段属性,但2.0 API显示,不再是$ Fields属性.所以你必须:

public $components = array(
    'Session',
    'Auth' => array(
        'authenticate' => array(
            'Form' => array(
                'fields' => array('username' => 'email')
            )
        )
    )
);

请告诉我它是如何工作的!
