Cakephp更新密码

Question

我正在尝试编辑我的会员密码之一（用户已允许我输入密码）。

现在，对于此功能，我将执行以下操作：

        if (!$this->User->exists($id)) {
        throw new NotFoundException(__('Invalid USer'));
    }
    if ($this->request->is('post') || $this->request->is('put')) {
        if ($this->User->save($this->request->data)) {
            $this->Session->setFlash(__('The User has been saved'));
            $this->redirect(array('action' => 'index'));
        } else {
            $this->Session->setFlash(__('The User could not be saved. Please, try again.'));
        }
    } else {
    }
}

但是，当我尝试保存时，出现以下错误：

2013-10-21 11:53:53 Error: [PDOException] SQLSTATE[23000]: Integrity constraint violation: 1062 Duplicate entry 'MarcEmp' for key 'username'

因此，它尝试插入一个新条目。

有人知道我在做什么错吗？

您忘记将当前ID设置为要更新，因此Cake在默认情况下将尝试创建新记录。 尝试添加：

$this->User->id = $id;

在保存操作之前。 因此，您的整个功能应如下所示：

/**
 * Edit an existing user.
 *
 * @param int $id The user id to edit.
 */
public function edit($id) {
    if (!$this->User->exists($id)) {
        throw new NotFoundException(__('Invalid User'));
    }
    if ($this->request->is('post') || $this->request->is('put')) {
        $this->User->id = $id; // <-- Add it here
        if ($this->User->save($this->request->data)) {
            $this->Session->setFlash(__('The User has been saved'));
            $this->redirect(array('action' => 'index'));
        } else {
            $this->Session->setFlash(__('The User could not be saved. Please, try again.'));
        }
    }
}
