cakephp - 错误 : Call to a member function newEntity() on boolean

Question

我是 cakephp 的新手。我已经完成了所有必需的步骤，但仍然无法使用 cakephp 将数据保存到数据库中

Articlecontroller.php 中的 adduser 函数代码:

public function adduser()
{
    $user = $this->Users->newEntity();
    if ($this->request->is('post')) {
        $user = $this->Users->patchEntity($user, $this->request->getData());

        // Hardcoding the user_id is temporary, and will be removed later
        // when we build authentication out.
        $user->user_id = 1;

        if ($this->Users->save($user)) {
            $this->Flash->success(__('Your article has been saved.'));
            return $this->redirect(['action' => 'index']);
        }
        $this->Flash->error(__('Unable to add your article.'));
    }
    $this->set('article', $user);
}

UserTable模型代码:

<?php
// src/Model/Table/ArticlesTable.php
namespace App\Model\Table;

use Cake\ORM\Table;

class UsersTable extends Table
{
    public function initialize(array $config)
    {
        $this->addBehavior('Timestamp');
    }
}

到我的本地主机上的数据库表:

我想你忘了在 Controller 中加载用户模型。在第一行之前在函数 adduser() 中添加这一行应该是固定的。它应该看起来像这样。

public function adduser()
{
    $this->loadModel('Users');
    $user = $this->Users->newEntity();
