CakePHP 3表名带下划线

Question

我是CakePHP的新手。我正在使用cakephp 3.2

我创建了一个表stock_exchanges和控制器StockExchangesController.php

我的控制器代码：

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:id="@+id/main_layout"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context="com.example.vikash.mydrawingapp.MainActivity">

    <Button
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="clear"
        android:onClick="clearCanvas"
        android:layout_alignParentBottom="true"
        android:layout_centerHorizontal="true" />
</RelativeLayout>

我想在未创建表类的情况下访问表。

以下行给出了错误

<?php
namespace App\Controller;

use Cake\ORM\TableRegistry;
use Cake\Core\Configure;
use Cake\Network\Exception\NotFoundException;
use Cake\View\Exception\MissingTemplateException;

class StockExchangesController extends AppController
{
    public function initialize()
    {
        parent::initialize();
        $this->loadComponent('RequestHandler');
        $this->loadComponent('Flash'); // Include the FlashComponent
    }

    public function index()
    {
        $stockExchanges = $this->StockExchanges->find('all');
        $this->set(compact('stockExchanges'));
    }

}
?>

错误是

错误：在非对象上调用成员函数find（） 文件D：\ wamp \ www \ Projects \ cakephp \ src \ Controller \ StockExchangesController.php 行：20

修改 @AIPD TECH在下面的评论中提到

$ stockExchanges = TableRegistry :: get（＆＃39; StockExchanges＆＃39;）;

如果表名是帖子，那么我可以使用$ this-＆gt; Posts-＆gt; find（＆＃39; all＆＃39;）; 。那么$ this-＆gt; StockExchanges-＆gt; find（＆＃39; all＆＃39;）;不是用下划线访问表格的方法吗？我必须使用TableRegistry吗？

另外，请注意我无法访问我的控制器StockExchangesController作为/ stock_exchanges /，我只能访问/ stockexchanges /

请帮忙。
