Cakephp 为什么我的应用程序中会出现无效论坛？

我试图开发一个论坛，但我对函数索引的键有问题，我测试它是否存在，Cakephp发现这个论坛不存在，但在我的数据库中我有一个存在的论坛。每次我点击有问题的论坛链接时，我都会得到无效的论坛。我想知道为什么，我认为模型之间的连接是正确的。有点不对劲，但我不知道在哪里。多谢各位

主题控制器：

public function index($forumId=null) {
        //debug($forumId);
        if (!$this->Topic->Forum->exists($forumId)) {
            throw new NotFoundException(__('Invalid forum'));
        }

        $forum = $this->Topic->Forum->read(null,$forumId);
        $this->set('forum',$forum);

        $this->Paginator->settings['contain'] = array('User','Message'=>array('User'));
        $this->set('topics', $this->Paginator->paginate());
    }

<?php
App::uses('AppController', 'Controller');

class ForumsController extends AppController {

    public $components = array('Paginator');

    public function beforeFilter() {
        $this->Auth->allow();
    }

    public function index() {
        $this->Paginator->settings['contain'] = array('Topic', 'Message'=>array('User','Topic'));
        $this->set('forums', $this->Paginator->paginate());
    }

}

示范论坛：

<?php
App::uses('AppModel', 'Model');

class Forum extends AppModel {

    public $validate = array(
        'name' => array(
            'notEmpty' => array(
                'rule' => array('notEmpty'),
                //'message' => 'Your custom message here',
                //'allowEmpty' => false,
                //'required' => false,
                //'last' => false, // Stop validation after this rule
                //'on' => 'create', // Limit validation to 'create' or 'update' operations
            ),
        ),
    );

    //The Associations below have been created with all possible keys, those that are not needed can be removed

    public $hasMany = array(
        'Message' => array(
            'className' => 'Message',
            'foreignKey' => 'forum_id',
            'dependent' => false,
            'conditions' => '',
            'fields' => '',
            'order' => '',
            'limit' => '',
            'offset' => '',
            'exclusive' => '',
            'finderQuery' => '',
            'counterQuery' => ''
        ),
        'Topic' => array(
            'className' => 'Topic',
            'foreignKey' => 'forum_id',
            'dependent' => false,
            'conditions' => '',
            'fields' => '',
            'order' => '',
            'limit' => '',
            'offset' => '',
            'exclusive' => '',
            'finderQuery' => '',
            'counterQuery' => ''
        )
    );

}

以及查询：

Page Introuvable Invalid forum

La page que vous avez essayez d'atteindre n'existe pas
(default) 4 queries took 0 ms   Nr  Query   Error   Affected    Num. rows   Took (ms)
1   SELECT `Forum`.`id`, `Forum`.`name`, `Forum`.`created`, `Forum`.`modified` FROM `forums` AS `Forum` WHERE `Forum`.`id` = 1 LIMIT 1      1   1   0
2   SELECT `Message`.`id`, `Message`.`topic_id`, `Message`.`forum_id`, `Message`.`created`, `Message`.`modified`, `Message`.`content`, `Message`.`user_id` FROM `messages` AS `Message` WHERE `Message`.`forum_id` = (1)        1   1   0

ForumsController：

public function index($forumId=null) {
        //debug($forumId);
        if (!$this->Topic->Forum->exists($forumId)) {
            throw new NotFoundException(__('Invalid forum'));
        }

        $forum = $this->Topic->Forum->read(null,$forumId);
        $this->set('forum',$forum);

        $this->Paginator->settings['contain'] = array('User','Message'=>array('User'));
        $this->set('topics', $this->Paginator->paginate());
    }

<?php
App::uses('AppController', 'Controller');

class ForumsController extends AppController {

    public $components = array('Paginator');

    public function beforeFilter() {
        $this->Auth->allow();
    }

    public function index() {
        $this->Paginator->settings['contain'] = array('Topic', 'Message'=>array('User','Topic'));
        $this->set('forums', $this->Paginator->paginate());
    }

}

ForumsController的功能索引，我可以在其中看到我创建的论坛，并可以单击链接：

          <div class="col-lg-12 ">
                <table class="table table-bordered">

                            <th>Activity</th>
                        </tr>
                    </thead>

在操作的第一行执行pr$this->Topic->Forum->findById$forumId，而不是$debug$forumId，并向我们展示它的输出。同时给出一个例子，说明什么是$forumId。你能把你的问题格式化一点，更好的标点和语法吗？对不起，我来自法国：/i添加了pr$this->Topic->Forum->findById$forumId，正如你所看到的，我应该得到两个论坛id为1的主题。但我得到这个消息无效论坛！谢谢你的帮助！我编辑了我的帖子
