Question

我遇到了一个奇怪的问题，在编辑视图中验证了用户名（如标题所示），这使我无法保存表单。我在这个视图中没有输入用户名，所以为什么这会被验证（并且失败）？

验证如下：

var $validate = array(
               'username' => array(
            'empty' => array(
                                'rule' => 'notEmpty',
                                'required' => true,
                                'allowEmpty' => false,
                                'message' => 'Username is required',
            ),
            'isUnique' => array(
                                'rule' => 'isUnique',
                                'message' => 'This username has already been taken'
            ),
            'pattern' => array(
                                'rule' => array('custom','/[a-zA-Z0-9\_\-]{6,}$/i'),
                                'message' => 'Must be 6 characters or longer with no spaces',
            ),
            'length' => array(
                                'rule' => array('maxLength', 15),
                                'message' => 'Please keep username under 15 characters',
            ),
            'notEmpty' => array(
                                'rule' => 'notEmpty',
                                'message' => 'Username cannot be empty',
            )
);

下面的编辑功能：

   function edit($id = null) {
            $this->set('title_for_layout', 'Edit Profile');
            unset($this->User->validate['email']['email']);
            unset($this->User->validate['username']);
            if($this->Auth->user('id')==$id) {
                $this->set('user', $this->User->read(null, $id));
                } else {
                    $this->Session->setFlash(__('You are not authorised to edit other member profiles', true));
                    $this->redirect(array('action' => 'index'));
        }
        if (!empty($this->data)) {
            if ($this->User->save($this->data)) {
                $this->Session->setFlash(__('Your profile has been saved', true));
                $this->redirect(array('action' => 'index'));
            } else {
                $this->Session->setFlash(__('Your profile could not be saved. Please, try again.', true));
            }
        }
        if (empty($this->data)) {
            $this->data = $this->User->read(null, $id);
        }
        $groups = $this->User->Group->find('list');
        $this->set(compact('groups'));
    }

我取消设置username然后只允许我保存表单，但这不是正确的方法。任何人都可以对此有所了解吗？

非常感谢！

Answer 1

required => true使'用户名'键成为必填字段，这意味着如果您只是尝试更新设置或没有用户名密钥的内容，则会失效。

我自己没有这样做，但尝试将'on' => 'create'添加到empty规则中，以便它仅在创建记录时适用。

即使表单中没有字段，也会验证用户名
