php - 插件模型关联在 cakephp 2.3 中无法使用 cake ACL 工作

Question

我只是想在名为“Cauth”的插件中实现 Cakephp ACL 用户身份验证。我之前实现的同样的东西工作得很好。这次不同的是，它在插件下。在这里，在 Controller 中， $this->用户->组->find('list');不管用。我收到以下 fatal error :

Fatal Error

Error: Call to a member function find() on a non-object
File: my_dir_path\app\Plugin\Cauth\Controller\UsersController.php
Line: 60

Notice: If you want to customize this error message, create app\View\Errors\fatal_error.ctp

我的代码如下:

群组模型:

var $useTable = 'groups';
public $hasMany = array (
    'User' => array (
        'className'    => 'Cauth.User',
        'foreignKey'   => 'group_id',
        'dependent'    => false,
        'conditions'   => '',
        'fields'       => '',
        'order'        => '',
        'limit'        => '',
        'offset'       => '',
        'exclusive'    => '',
        'finderQuery'  => '',
        'counterQuery' => ''
    )
);

用户模型:

var $useTable = 'users';
public $belongsTo = array (
    'Group' => array (
        'className'  => 'Cauth.Group',
        'foreignKey' => 'group_id',
        'conditions' => '',
        'fields'     => '',
        'order'      => ''
    )
);

用户 Controller 添加操作，组选择框不起作用。

用户 Controller 添加操作:

App::uses('CauthAppController', 'Cauth.Controller');
class UsersController extends CauthAppController {
public function add() {
    if ($this->request->is('post')) {
        $this->User->create();
        if ($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.'));
        }
    }

    $groups = $this->User->Group->find('list');
    $this->set(compact('groups'));

}

谁能帮我解决这个问题。

特别说明: 目前正在处理以下案例。

情况1:

如果我从 Controller 绑定(bind)模型，它就可以正常工作。

$this->User->bindModel(
    array ('belongsTo' => array ('Group'))
);

即

public function add() {
    $this->User->bindModel(
        array ('belongsTo' => array ('Group'))
    );
    if ($this->request->is('post')) {
        $this->User->create();
        if ($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.'));
        }
    }

    $groups = $this->User->Group->find('list');
    $this->set(compact('groups'));

}

情况2:

如果我允许所有操作名称。管理员拥有所有权限，尽管我还需要为管理员编写 beforeFilter。

public function beforeFilter() {
    parent::beforeFilter();
    $this->Auth->allow('index', 'add');
}

我又找到了一个使其可行的案例。

情况3:

我的 AppController 的代码是 -

class AppController extends Controller {


    public $helpers    = array ('Form', 'Time', 'Html', 'Session', 'Js', 'DebugKit.Toolbar');
    public $counter    = 0;
    public $components = array (
        'DebugKit.Toolbar',
        'RequestHandler',
        'Acl',
        'Auth' => array (
            'authorize' => array (
                'Actions' => array ('actionPath' => 'controllers')
            )
        ),
        'Session'
    );

    public function beforeFilter() {
        //Configure AuthComponent
        $this->Auth->loginAction    = array ('plugin'     => 'cauth', 'controller' => 'users', 'action'     => 'login');
        $this->Auth->logoutRedirect = array ('plugin'     => 'cauth', 'controller' => 'users', 'action'     => 'login');
        $this->Auth->loginRedirect  = array ('plugin'     => '', 'controller' => 'pages', 'action'     => 'display');

    }

}

在这种情况下它不起作用。但当我成功时 -

class AppController extends Controller {

    public $helpers    = array ('Form', 'Time', 'Html', 'Session', 'Js', 'DebugKit.Toolbar');
    public $counter    = 0;
    public $components = array (
        'DebugKit.Toolbar',
        'RequestHandler',
        'Acl',
        'Auth' => array (
            'authenticate' => array('Form')

        ),
        'Session'
    );

    public function beforeFilter() {
        //Configure AuthComponent
        $this->Auth->loginAction    = array ('plugin'     => 'cauth', 'controller' => 'users', 'action'     => 'login');
        $this->Auth->logoutRedirect = array ('plugin'     => 'cauth', 'controller' => 'users', 'action'     => 'login');
        $this->Auth->loginRedirect  = array ('plugin'     => '', 'controller' => 'pages', 'action'     => 'display');

    }

}

然后协会再次开始工作。仍然无法理解这个组件声明有什么问题。

public $components = array (
    'DebugKit.Toolbar',
    'RequestHandler',
    'Acl',
    'Auth' => array (
        'authorize'    => array (
            'Actions' => array ('actionPath' => 'controllers')
        )
    ),
    'Session'
);

如果我不这样声明，我的 ACL 将不起作用。即所有组都获得相同的权限。

请帮助我。我对此已经有很长一段时间了。

Answer 1

经过长时间的努力，我终于从以下链接找到了解决方案 -

https://cakephp.lighthouseapp.com/projects/42648/tickets/2464-plugin-using-acl-not-loading-proper-model

当我使用 Auth 组件时，用户 Controller 没有使用 Cauth.user 模型。它是使用 AppModel 加载的。但没有身份验证组件，它可以正常工作。这样使用 auth 组件的正确方法将是

    'Auth' => array (
        'authorize' => array (
            'Actions' => array (
                'actionPath' => 'controllers',
                'userModel'  => 'Cauth.User',
            ),
        )
    ),

这就是整个 AppController -

class AppController extends Controller {

    public $helpers    = array ('Form', 'Time', 'Html', 'Session', 'Js', 'DebugKit.Toolbar');
    public $counter    = 0;
    public $components = array (
        'DebugKit.Toolbar',
        'RequestHandler',
        'Acl',
        'Auth' => array (
            'authorize' => array (
                'Actions' => array (
                    'actionPath' => 'controllers',
                    'userModel'  => 'Cauth.User',
                ),
            )
        ),
        'Session'
    );

    public function beforeFilter() {
        //Configure AuthComponent
        $this->Auth->loginAction    = array ('plugin'     => 'cauth', 'controller' => 'users', 'action'     => 'login');
        $this->Auth->logoutRedirect = array ('plugin'     => 'cauth', 'controller' => 'users', 'action'     => 'login');
        $this->Auth->loginRedirect  = array ('plugin'     => '', 'controller' => 'pages', 'action'     => 'display');

    }

}

现在一切正常。感谢大家。
