如何在Contao新闻扩展中映射图像？

Question

我正在接受最新的Contao 4的新闻报道。

Can anyone please explain how the image files are related to tl_news table ?
Currently for my migration I have imagepath and imagename for the respective image.

When I add an image to a news in contao through backend. The following fields get updated in database. 

addImage =＆gt; 1，

singleSRC =＆gt; f52a3871946211e782662e3e7a222c66

But when I search singleSRC in tl_files.uuid , it doesn't show any records.

请帮助我找到在迁移到Contao 4期间如何映射图像

Answer 1

singleSRC中的tl_news字段（例如tl_content和tl_calendar_events）是二进制字段，其中包含与之相关的UUID tl_files.uuid字段。

我不知道你是如何实现新闻迁移脚本的。但是在Contao框架中，这就是从singleSRC获取文件路径的方法，例如：

// $objNews is a \Contao\NewsModel object
$objFile = \Contao\FilesModel::findByUuid($objNews->singleSRC);
$strPath = $objFile->path;

这就是你如何将它添加回其他地方的新新闻：

// $strPath contains the relative path of the file on the other installation
$objFile = \Contao\Dbafs::addResource($strPath);
$objNews->singleSRC = $objFile->uuid;
