cakephp 3编辑用户用户名和密码-找不到当前实体的表类

我正在使用CakePHP3.5（今天运行了更新）制作我的第一个非教程web应用程序。我正在尝试设置我的应用程序，以便编辑我的用户帐户详细信息（用户名和密码）。 我不确定我做了什么，但我无法在登录时实际访问我的edit.ctp（视图）。我一直收到一个“找不到当前实体的表类”错误

我的最终目标是让用户能够编辑他们的用户名（这是一个电子邮件地址）并在他们愿意的时候更改密码

有人能帮我找出哪里出了问题，为什么我总是遇到“找不到当前实体的表类”错误，以及我能做些什么来修复它。 我已经阅读了尽可能多的相关文章。我尝试过各种“Isauthorized”函数版本，我不断地得到相同的错误，所以我确信这是我不知道要寻找的东西

下面是我的代码：

The User.php file:

<?php
namespace App\Model\Entity;

use Cake\Auth\DefaultPasswordHasher;
use Cake\ORM\Entity;

/**

class User extends Entity
{

    /**

     * (or remove it), and explicitly make individual fields accessible as needed.
     *
     * @var array
     */
    protected $_accessible = [
        '*' => true,
        'id' => false,
    ];
    protected function _setPassword($password)
    {
        return (new DefaultPasswordHasher)->hash($password);
    }
}

The UsersTable.php file:
<?php 
namespace App\Model\Table;

            ]);

        $validator
            ->add('terms_of_service', 'valid', ['rule' => 'boolean'])
            ->notEmpty('terms_of_service','You must agree to the terms of service to register');

        return $validator;
    }

    public function buildRules(RulesChecker $rules)
    {
        $rules->add($rules->isUnique(['username']));
        return $rules;
    }
}

好的，经过反复试验，我已经解决了这个问题。这是一个简单的修复，虽然我不知道为什么它工作。。。因此，如果有人能解释一下，那就太好了：我将控制器文件编辑功能中的

$user

变量更改为

$users

，将edit.ctp文件中的

$user

变量更改为

$users

，嘿，它成功了。

问题是，在

beforeRender

方法您可以使用此方法

    $this -> set('user', $this -> Auth -> user());

这意味着您将与所有控制器和操作共享记录的当前用户

还请注意，在用户控制器中的编辑操作中，您还调用了变量

$user

，并通过

集将其发送到视图中

这就是问题的根源，这就是为什么如果您通过
用户更改名称
它会起作用！！在用户控制器中的编辑操作中发送的
$user
方法与
$user
方法之间似乎存在冲突，David，您使用这种方式授权的是什么原因？如果您的孩子有一个未授权的，它应该称之为。你不必让你的应用程序控制器调用你的子类IsAuthorized函数。@chrishick No。。。在我试图解决我的问题时，我看到的一个例子就是以这种方式使用它。我以前的isAuthorized看起来是这样的：
公共函数isAuthorized（$user）{if（isset（$user['role']）&&$user['role']=='admin'）{return true；}return false；}
你也可以尝试一些简单的方法，比如管理基于角色的访问。那么就不需要在控制器中进行黑客攻击了。谢谢@mark，我将尝试一下。但是在您的示例中，看起来您还需要一些基于行的访问。那就行不通了。哦，我也有类似的问题，这就是原因。非常感谢。
