在 cakephp 中检查 'isUniqueUsername' 似乎不起作用？

Question

我有一个注册表单，当用户注册时，它会询问他们的用户名、密码和电子邮件。对于用户名，我有一些规则，例如：

必须是 5-12 个字符
必须是唯一的
只能使用字母、数字和破折号

尽管如此，我似乎无法让我的表单捕捉重复的用户名，我希望有人能帮我解决这个问题！

这是我的 User.php 模型的验证：

public $validate = array(
        'username' => array(
            'nonEmpty' => array(
                'rule' => array('notEmpty'),
                'message' => 'A username is required',
                'allowEmpty' => false
            ),
            'between' => array( 
                'rule' => array('between', 5, 15), 
                'required' => true, 
                'message' => 'Usernames must be between 5 to 15 characters'
            ),
             'unique' => array(
                'rule'    => array('isUniqueUsername'),
                'message' => 'This username is already in use'
            )
        )
);

为了示例，我删除了第三条规则 (alpha/number/dash)

接着我的函数检查我的数据库中的用户名：

function isUniqueUsername($check) {


$username = $this->find(
    'all',
    array(
        'fields' => array(
            'User.id',
            'User.username'
        ),
        'conditions' => array(
            'User.username' => $check['username']
        )
    )
);

if(!empty($username)){
    if($this->data[$this->alias]['id'] == $username['']['id']){
        return true; 
    }else{
        return false; 
    }
}else{
    return true; 
}

}

这里是 "Register"

的控制器函数

public function register() {
        if ($this->request->is('post')) {

            $this->User->create();
            if ($this->User->save($this->request->data)) {
                $this->Session->setFlash(__('The user has been created'));
                $this->redirect($this->Auth->redirect());
            } else {
                $this->Session->setFlash(__('The user could not be created. Please, try again.'));
            }   
        }
    }

Answer 1

改变

'unique' => array(
    'rule'    => array('isUniqueUsername'),
    'message' => 'This username is already in use'
 )

到

 'unique' => array(
     'rule' => 'isUnique',
     'message' => 'This username is already in use'
 )

你不需要那个函数来检查唯一性，Cake 用魔法为你做了。
