Question

我是Laravel的新人，请我。

我正在研究laravel项目，该项目已由其他开发人员完成。我被困在Model :: with function。

QxAppDetail::with(['qx_app_translation', 'qx_app_pages.qx_page_translation',
                    'user_app_info' => function($query) use($device_registration_id) {
                        $query->where('device_registration_id', $device_registration_id);
                    }])->selectRaw($this->table . '.app_id, '
                        . 'if(qx_app_details.app_icon = "", "", CONCAT("' . $this->app_icon_path . '","/", qx_app_details.app_icon)) as app_icon, '
                        . 'if(qx_app_details.download_link="","",CONCAT("' . $apk_url . '",qx_app_details.download_link)) as download_link,'
                        . $this->table . '.open_link, qx_app_details.package_name, qx_app_details.qeexo_default_app, qx_app_details.service_id,qx_app_details.sort_order,qx_app_details.is_enabled')
                ->orderBy('qx_app_details.sort_order', 'ASC')
                ->whereIn('qx_app_details.device_registration_id', array(0, $device_registration_id))
                ->get();

在上面的查询中，我需要使用像

这样的列来连接url

'if(qx_app_details.download_link="","",CONCAT("' . $apk_url . '",qx_app_details.download_link)) as download_link,'

在qx_app_pages中。但是我无法做到这一点。

qx_app_pages和qx_page_translation是表格

当前查询输出为：
