Laravel - 带有函数调用访问器的帮助文件

如何解决Laravel - 带有函数调用访问器的帮助文件

我有一个帮助文件，其中包含可从项目的所有部分访问我的功能。

在这些函数中，我有一个从模型调用访问器的函数，但在使用时出现错误。

这里的功能：

function placeholder_decode($placeholder,$documento)
{
    $variables['#document.protocol_number_view#'] = $documento->protocol_number_view;
    
    $string = json_decode(str_replace(array_keys($variables),array_values($variables),$placeholder));

    return $string[0]->value;

}

访问者是对 $documento->protocol_number_view 的调用。

这是访问器的代码转化为模型代码：

public function getProtocolNumberViewAttribute()
{
    $format = Configuration::select("value")->where("company_id",$this->attributes['company_id'])->where("name","prot_format")->get();

    if ($this->attributes['protocol_number'] != 0) {
        $number = placeholder_decode($format,$this);
    } else {
        $number = "";
    }
    return $number;
}

这是我得到的错误：

[2021-03-10 20:27:54] local.ERROR: ErrorException: Undefined property: App\Document::$protocol_number_view in /var/www/protocol/app/helpers.PHP:15

这是 dd($documento) 到 placeholder_decode() 函数的结果：
