Codeignitor 4 未保存到 mysql db

Question

我正在尝试将数据保存到 mysql 数据库中，该应用程序没有保存数据，并且没有显示任何错误。

我在第三方\身份验证中有我的模型、视图和控制器。

我有其他页面在同一目录中运行良好，但一页（设置）只是不会将输入保存到数据库中。

// 我的 Model 代码：//

<?php namespace Auth\Models;

use CodeIgniter\Model;

class SettingsModel extends Model
{
    protected $table      = 'appsettings';
    protected $primaryKey = 'id';

    protected $returnType = 'array';
    protected $useSoftDeletes = false;

    // this happens first, model removes all other fields from input data
    protected $allowedFields = [
        'appname', 'frame_ver', 'app_ver'
    ];

    protected $useTimestamps = true;
    protected $createdField  = 'created_at';
    protected $updatedField  = 'updated_at';
    protected $dateFormat    = 'int';

    protected $validationRules = [];

    // we need different rules for registration, account update, etc
    protected $dynamicRules = [
        'registration' => [
            'appname'               => 'required',
            'frame_ver'             => 'required',
            'app_ver'               => 'required'
        ]
    ];

    protected $validationMessages = [];

    protected $skipValidation = false;

    
    //--------------------------------------------------------------------

    /**
     * Retrieves validation rule
     */
    public function getRule(string $rule)
    {
        return $this->dynamicRules[$rule];
    }

    //--------------------------------------------------------------------

}

我的 Controller 代码：

<?php
namespace Auth\Controllers;

use CodeIgniter\Controller;
use Config\Email;
use Config\Services;
use Auth\Models\SettingsModel;

class SettingsController extends Controller
{

    /**
     * Access to current session.
     *
     * @var \CodeIgniter\Session\Session
     */
    protected $session;

    /**
     * Authentication settings.
     */
    protected $config;


    //--------------------------------------------------------------------

    public function __construct()
    {
        // start session
        $this->session = Services::session();

        // load auth settings
        $this->config = config('Auth');
    }

    //--------------------------------------------------------------------

    /**
     * Settings Functions
     */
    public function Settingsfx()
    {
        if (! $this->session->isLoggedIn) {
            return redirect()->to('login');
        }

        return view($this->config->views['settings'], [
            'userData' => $this->session->userData,
            'config' => $this->config
        ]);
    }


/**
     * Attempt to register settings.
     */
    public function addsettings()
    {
        helper('text');

        // save new user, validation happens in the model
        $users = new SettingsModel();
    //  $getRule = $appsettings->getRule('registration');
    //  $appsettings->setValidationRules($getRule);
        $user = [
            'appname'           => $this->request->getPost('appname'),
            'frame_ver'         => $this->request->getPost('frame_ver'),
            'app_ver'           => $this->request->getPost('app_ver')
        ];

        if (! $users->save($user)) {
            return redirect()->back()->withInput()->with('errors', $users->errors());
        }

    }
}

我在哪里混合东西？ 我已经尝试了两天了。 任何见解都将受到高度赞赏。
