致命错误：在布尔值上调用成员函数user（） [英] Fatal error: Call to a member function user() on boolean

问题描述

我必须在视图中使用已登录用户数据，因此在 AppController AUTH_USER $ c>在 beforeRender 函数中。

I have to use loggedIn user data in view therefore creating a variable AUTH_USER in AppController in beforeRender function.

82     public function beforeRender(Event $event)
83     {
84          if ($this->Auth->user('id')) {
85          $this->set('AUTH_USER', $this->Auth->user());
86          }
87          ...
88          ...
89     }

每当出现错误时，它不显示实际错误，而是显示以下错误，而没有样式格式

Whenever there is an error, instead of displaying actual error it shows following error without style formatting

Fatal error: Uncaught Error: Call to a member function user() on boolean in /path_to_app/src/Controller/AppController.php:84 
Stack trace: #0 /path_to_app/src/Controller/ErrorController.php(54): App\Controller\AppController->beforeRender(Object(Cake\Event\Event))

删除行 84-86 显示实际错误

AppController中的Auth组件加载的代码initialize（）

我编写了以下代码来加载 AUTH 组件。

I have written the following code to load the AUTH component.

$this->loadComponent('Auth', [
   'authenticate' => [
      'Form' => [
         'userModel' => 'Admins',
            'fields' => [
               'username' => 'email', 
               'password' => 'password'
             ]
         ]
      ],
      'loginAction' => [
         'controller' => 'Admins',
         'action' => 'index'
      ],
      'loginRedirect' => [
         'controller' => 'Admins',
         'action' => 'contentList'
       ],
      'authError' => 'Did you really think you are allowed to see that?',
      'logoutAction' => [
         'controller' => 'Pages',
         'action' => 'home'
       ]
]);

推荐答案

我有相同的错误，如果添加此行到 beforeRender（）应该起作用：

I had the same error and if you add this line to beforeRender() it should work:

$this->loadComponent('Auth');

可能是您未在 initialize（）中正确初始化组件（ ）函数。
