我的整个userscoontroller.php
:

public function index() {
$this->User->recursive = 0;
$this->set('users', $this->paginate());

public function view($id = null) {
$this->User->id = $id;

为什么会发生这种情况?确保在AppController中实际调用了Auth组件。如果没有AppController,请使用以下代码在控制器目录中创建
AppController.php
:
<?php
class AppController extends Controller {
}
?>
Auth组件在AppController中的公共变量中调用,因此控制器如下所示:
<?php
class AppController extends Controller {
public $components = array('Auth');
}
?>
Auth现在在整个应用程序中都可用。您还可以在UsersController中调用
AuthComponent
,但这将使它仅对该特定控制器可用。您可能希望在整个应用程序中使用身份验证。只是您所说内容的附加内容。在CakePHP 2.0中,AppController位于Controller文件夹中,而不是1.3中的app文件夹中。这把我搞砸了,因为我调用的是组件,而不是实际的AppController本身!
