cakephp 3编辑用户用户名和密码 - 无法找到当前实体的表类

我正在使用cakephp 3.5(今天运行更新)来创建我的第一个非教程Web应用程序.我正在尝试设置我的应用,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,但在登录时我实际上无法访问我的edit.ctp(视图).我一直收到"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编辑他们的用户名(这是一个电子邮件地址),并在他们想要的时候更改他们的密码.

有人可以帮助我锻炼我出错的地方,以及为什么我一直得到"无法找到当前实体的表类"错误以及我可以做些什么来解决它.我已经阅读了尽可能多的相关文章.我已经尝试了各种"isAuthorised"函数版本,并且我一直收到同样的错误,所以我确信这是我不知道该找什么的东西.

以下是我的代码:

The User.php file:

 true,
        'id' => false,
    ];
    protected function _setPassword($password)
    {
        return (new DefaultPasswordHasher)->hash($password);
    }
}

The UsersTable.php file:
table('users');
        $this->displayField('username');
        $this->primaryKey('id');

        $this->addBehavior('Timestamp');

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

    /**
     * Default validation rules.
     *
     * @param \Cake\Validation\Validator $validator Validator instance.
     * @return \Cake\Validation\Validator
     */
    public function validationDefault(Validator $validator)
    {
         $validator
            ->notEmpty('username','Please supply your email address')
            ->add('username', 'valid', ['rule'=>'email']);

        $validator
            ->notEmpty('password','Please supply your password');

        $validator
            ->notEmpty('role','Please select your account type')
            ->add('role','inList',[
                '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;
    }
}

The relevant pieces UsersController.php file:

Auth->allow(['signup','logout']);
        $this->Auth->deny(['index']);

    }
    // The owner of an user can edit and delete it
    public function isAuthorized($user)
    {
        if (in_array($this->request->action, ['edit', 'delete','view'])) {
            if ($this->Users->isOwnedBy($user['id'])) {
                return true;
            }
        }
        return parent::isAuthorized($user);
    }

    /**
     * Edit method
     *
     * @param string|null $id User id.
     * @return void Redirects on successful edit, renders view otherwise.
     * @throws \Cake\Network\Exception\NotFoundException When record not found.
     */
    public function edit($id = null)
    {
        $id = $this->Auth->user('id');
        $user = $this->Users->get($id, [
            'contain' => []
        ]); 
        if ($this->request->is(['patch', 'post', 'put'])) {
            $user = $this->Users->patchEntity($user, $this->request->data);
            if ($this->Users->save($user)) {
                $this->Flash->success(__('Your account has been edited.'));
                return $this->redirect(['controller','Users','action' => 'edit']);
            } else {
                $this->Flash->error(__('The user could not be saved. Please, try again.'));
            }
        }
        $this->set(compact('user'));
        $this->set('_serialize', ['user']);
    }

问题是在你的AppControllerin beforeRender方法中你有这个..

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

这意味着您将与所有控制器和操作共享当前用户.

并且还要注意,在用户控制器的编辑操作中,您还调用了一个变量,$user然后通过set... 将其发送到视图中.

所以这就是问题的根源,这就是为什么如果你通过users它更改名称的原因!! 似乎$user发送beforeRender方法与$user用户控制器中的编辑操作中发送的内容之间存在冲突
