php - cakephp 3 编辑用户用户名和密码 - 无法找到当前实体的表类

Question

我正在使用 cakephp 3.5(今天运行更新)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，以便我可以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，但我在登录时实际上无法访问我的 edit.ctp( View )。我不断收到“无法找到当前实体的表类”错误。

我最终的目标是让用户能够在需要时编辑他们的用户名(这是一个电子邮件地址)并更改他们的密码。

有人可以帮我解决我出错的地方，为什么我总是收到“无法找到当前实体的表类”错误以及我可以做些什么来修复它。我已经阅读了尽可能多的相关文章。我已经尝试了各种“isAuthorised”功能版本，但我不断收到相同的错误，所以我确信这是我不知道要寻找什么的东西。

下面是我的代码:

The User.php file:

<?php
namespace App\Model\Entity;

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

/**
 * User Entity.
 *
 * @property int $id
 * @property string $username
 * @property string $password
 * @property string $role
 * @property \Cake\I18n\Time $created
 * @property \Cake\I18n\Time $activity_date
 * @property bool $terms_of_service
 * @property bool $paid
 * @property \Cake\I18n\Time $paid_date
 * @property \Cake\I18n\Time $paid_until
 * @property bool $verified
 * @property \App\Model\Entity\Agent[] $agents
 */
class User extends Entity
{

    /**
     * Fields that can be mass assigned using newEntity() or patchEntity().
     *
     * Note that when '*' is set to true, this allows all unspecified fields to
     * be mass assigned. For security purposes, it is advised to set '*' to false
     * (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;

use App\Model\Entity\User;
use Cake\ORM\Query;
use Cake\ORM\RulesChecker;
use Cake\ORM\Table;
use Cake\Validation\Validator;

    {
        parent::initialize($config);

        $this->table('users');
        $this->displayField('username');
        $this->primaryKey('id');

        $this->addBehavior('Timestamp');

        $this->hasMany('Agents', [
            'foreignKey' => 'user_id'
        ]);
    }

    /**

    {

            ->add('username', 'valid', ['rule'=>'email']);

        $validator

        $validator

                'rule' => ['inList',['agent','buyer']],
                'message' => 'Please select a valid role'
            ]);

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

        return $validator;
    }
    public function isOwnedBy($userId)
    {
        return $this->exists(['id' => $userId]);
    }
    /**
     * Returns a rules checker object that will be used for validating
     * application integrity.
     *
     * @param \Cake\ORM\RulesChecker $rules The rules object to be modified.
     * @return \Cake\ORM\RulesChecker
     */
    public function buildRules(RulesChecker $rules)
    {
        $rules->add($rules->isUnique(['username']));
        return $rules;
    }
}

Answer 1

问题是在 beforeRender 方法中的 AppController 中你有这个..

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

这意味着您将与所有 Controller 和操作共享当前登录的用户..

还要注意，在用户 Controller 中的编辑操作中，您还调用了一个变量 $user 并通过 set 将其发送到 View ...

所以这就是你的问题的根源，这就是为什么如果你通过 users 更改名称它有效!似乎在 beforeRender 方法中发送的 $user 与在用户 Controller 中的编辑操作中发送的 $user 之间存在冲突
