Question

我正在使用cakePHP编写客户管理系统（我曾尝试使用此框架进行构建的第一件事），而且我在努力弄清楚如何在添加新客户时验证某些字段。每个客户都有一个我需要手动添加的ID，以及一个必须唯一但可以为空的用户名。这就是我想要发生的事情：

添加新客户时：
- 检查该ID是否已存在并提醒用户是否存在（而不是添加用户）
- 检查用户名是否已存在，如果确实存在，则提醒用户（而不是添加用户）
更新客户资料时（此时无法修改ID）：
- 如果用户名已被修改，请检查其是否已存在并提醒用户。

现在看来，每当我尝试添加具有现有ID的用户时，cakePHP只会用新信息覆盖现有id的信息。

我尝试了几种验证选项，但似乎没有任何效果。

这是第一个：

public $validate = array(
        'id' => array(
            'idRule-1' => array(
                'on' => 'create',
                'rule' => 'uniqueID',
                'message' => 'This Oracle ID already exists.',
                'last' => false
            ),
            'idRule-2' => array(
                'rule' => 'numeric',
                'message' => 'Oracle ID can only contain numbers.',
                'last' => false
            ),
        ), 
        'username' => array(
            'userRule-1' => array(
                'on' => 'create',
                'rule' => 'uniqueUser',
                'message' => 'This username already exists',
                'last' => false,
            ),
            'userRule-2' => array(
                'on' => 'update',
                'rule' => 'oneUser',
                'message' => 'The eBay username you are trying to modify already belongs to another seller',
                'last' => false,
            ),
        )
    );

public function uniqueID() {
        return ($this->find('count', array('conditions' =>array('Seller.id' => $this->data['Seller']['id']))) == 0);
    }

    public function uniqueUser() {
        return ($this->find('count', array('conditions' =>array('Seller.username' => $this->data['Seller']['username']))) == 0);
    }

    public function oneUser() {
        return ($this->find('count', array('conditions' =>array('Seller.username' => $this->data['Seller']['username']))) == 1);
    }

和第二个（仅用于id）：

public $validate = array(
        'id' => array(
            'unique' => array(
                'rule' => 'isUnique',
                'on' => 'create',
                'message' => 'This Oracle ID already exists.',
            )
        )
    );

以下是控制器的add（）和edit（）方法：

public function add() {
    if ($this->request->is('post')) {
        $this->Seller->create();
        if ($this->Seller->save($this->request->data)) {
            $this->Session->setFlash(__('The seller has been saved'));
            $this->redirect(array('action' => 'index'));
        } else {
            $this->Session->setFlash(__('The seller could not be saved. Please, try again.'));
        }
    }
    $accountManagers = $this->Seller->AccountManager->find('list');
    $primaries = $this->Seller->Primary->find('list');
    $thirdParties = $this->Seller->ThirdParty->find('list');
    $sites = $this->Seller->Site->find('list');
    $meetings = $this->Seller->Meeting->find('list');
    $this->set(compact('accountManagers', 'primaries', 'thirdParties', 'sites', 'meetings'));
}

/**
 * edit method
 *
 * @throws NotFoundException
 * @param string $id
 * @return void
 */
    public function edit($id = null) {
        if (!$this->Seller->exists($id)) {
            throw new NotFoundException(__('Invalid seller'));
        }
        if ($this->request->is('post') || $this->request->is('put')) {
            $this->Seller->id = $id;
            if ($this->Seller->save($this->request->data)) {
                $this->Session->setFlash(__('The seller has been saved'));
                $this->redirect(array('action' => 'index'));
            } else {
                $this->Session->setFlash(__('The seller could not be saved. Please, try again.'));
            }
            debug($this->Seller->validationErrors);
        } else {
            $options = array('conditions' => array('Seller.' . $this->Seller->primaryKey => $id));
            $this->request->data = $this->Seller->find('first', $options);
        }
        $accountManagers = $this->Seller->AccountManager->find('list');
        $primaries = $this->Seller->Primary->find('list');
        $thirdParties = $this->Seller->ThirdParty->find('list');
        $sites = $this->Seller->Site->find('list');
        $meetings = $this->Seller->Meeting->find('list');
        $this->set(compact('accountManagers', 'primaries', 'thirdParties', 'sites', 'meetings'));
    }

非常感谢任何和所有提示！

如果您尝试保存的数据包含id，CakePHP会假定您正在更新现有记录。要在“create”上触发验证规则，不应设置id。如果设置了id，Cake将检查“更新”规则。

因此，您应该让数据库使用自动增量对新记录的ID进行影响，然后仅在编辑现有用户时管理验证。
