有没有更好的方法来改变用户密码在cakephp使用Auth？ [英] Is there a better way to change user password in cakephp using Auth?

问题描述

我自己学习cakephp。我试图创建一个具有changepassword功能的用户控制器。它的工作原理，但我不知道这是否是最好的方式，我不能googled这个有用的教程。
这是我的代码：

I am learning cakephp by myself. I tried to create a user controller with a changepassword function. It works, but I am not sure if this is the best way, and I could not googled up useful tutorials on this. Here is my code:

class UsersController extends AppController {

    var $name = 'Users';

    function login() {
    }

    function logout() {
        $this->redirect($this->Auth->logout());
    }

    function changepassword() {
        $session=$this->Session->read();
        $id=$session['Auth']['User']['id'];
        $user=$this->User->find('first',array('conditions' => array('id' => $id)));
        $this->set('user',$user);
        if (!empty($this->data)) {
            if ($this->Auth->password($this->data['User']['password'])==$user['User']['password']) {
                if ($this->data['User']['passwordn']==$this->data['User']['password2']) {
                // Passwords match, continue processing
                $data=$this->data;
                $this->data=$user;
                $this->data['User']['password']=$this->Auth->password($data['User']['passwordn']);
                $this->User->id=$id;
                $this->User->save($this->data);
                $this->Session->setFlash('Password changed.');
                $this->redirect(array('controller'=>'Toners','action' => 'index'));
                } else {
                    $this->Session->setFlash('New passwords differ.');
                    }
            } else {
                $this->Session->setFlash('Typed passwords did not match.');
            }
        }
    }
}

是旧密码，passwordn是新密码，password2是新密码。
有没有其他更多的coomon方法做蛋糕？

password is the old password, passwordn is the new one, password2 is the new one retyped. Is there any other, more coomon way to do it in cake?

推荐答案

我看到你验证和操纵数据。在模型中做这通常是一个更好的做法。我几天前实现了类似的功能。我的 change_password（）方法看起来有点像这样：

I see that you validate and manipulate data in the controller. Doing this in a model is generally a better practice. I implemented similar functionality just a few days ago. My change_password() method looks somewhat like this:

# app/controllers/users_controller.php
function change_password() {
    if (!empty($this->data)) {
        if ($this->User->save($this->data)) {
            $this->Session->setFlash('Password has been changed.');
            // call $this->redirect() here
        } else {
            $this->Session->setFlash('Password could not be changed.');
        }
    } else {
        $this->data = $this->User->findById($this->Auth->user('id'));
    }
}

这里是一个精简版的视图该方法：

And here's a stripped down version of the view used with that method:

# app/views/users/change_password.ctp
echo $this->Form->create('User');
echo $this->Form->input('id');
echo $this->Form->input('current_password');
echo $this->Form->input('password1');
echo $this->Form->input('password2');
echo $this->Form->end('Submit');

有趣的代码在模型中。我将表单中的字段添加到 validate 属性中，并写入了自定义验证方法。这允许我在应用程序中的任何其他地方使用password1和password2字段，例如，在注册表单上。

The code that does something interesting is in the model. I added the fields from the form to the validate property and wrote custom validation methods. This allows me to use password1 and password2 fields in any other place in the application, for example, on the registration form.

# app/models/user.php
var $validate = array(
    'current_password' => array(
        'rule' => 'checkCurrentPassword',
        'message' => '...'
    ),
    'password1' => array(
        'rule' => 'checkPasswordStrength',
        'message' => '...',
    ),
    'password2' => array(
        'rule' => 'passwordsMatch',
        'message' => '...',
    )
);

最后，在 beforeSave（） 回调模型我设置密码到 password1 的散列以准备要存储在数据库中的数据。

Finally, in the beforeSave() callback of the model I set password to the hash of password1 to prepare the data to be stored it in the database.
