CodeIgniter4：喜欢或不喜欢的功能允许两者都可以限制每个用户的一票

Question

我正在尝试在我的图像上传站点中实现类似或不喜欢的（Undislike）功能。我正在使用Ajax来实现这一目标，到目前为止，我已经能够将用户限制在每个上传页面的一个视图中，但是我无法将用户限制为“喜欢或不喜欢”的一票。他们目前可以做。

问题在于我的Model ActionModel.php中：

public function insertAction(array $request)
    {
        $image = new \App\Entities\Image();

        $request = $this->updateModified($request);

        switch($request['action']) {

            case 'dislike':

                $data = [
                    'action'    => 0,
                    'username'  => session()->get('username'),
                    'viewkey'   => $request['viewkey'],
                    'modified_at'  => $request['modified_at'],
                ];

                $image->setUserLiked($request['viewkey']);

                if ($image->userLiked === FALSE) {
                    
                    $this->builder()
                        ->insert($data);
                
                } else {

                    $this->builder()
                        ->set($data)
                        ->where(['action' => 1, 'username' => $data['username'], 'viewkey' => $data['viewkey']])
                        ->replace();
                }

                unset($image->setUserLiked);

                break;

            case 'undislike':

                $this->builder()
                    ->where('action', 0)
                    ->delete();

                break;

            case 'like':

               $data = [
                    'action'    => 1,
                    'username'  => session()->get('username'),
                    'viewkey'   => $request['viewkey'],
                    'modified_at'  => $request['modified_at'],
                ];

                $image->setUserDisliked($request['viewkey']);

                if ($image->userDisliked === FALSE) {
                    
                    $this->builder()
                        ->insert($data);

                        ->replace();
                }

                unset($image->userDisliked);

                break;

            case 'unlike':

                    ->delete();
