ModelAdmin中的Silverstripe文件关系未发布

问题描述

我使用SilverStripe4和ModelAdmin来管理数据对象.

Im using SilverStripe4 and the ModelAdmin to manage DataObjects.

DataObject在文件上具有has_one.到目前为止，一切正常，但是在前端控制器上，文件"关系中有一个空对象.

The DataObject has a has_one on File. Everything works so far but on frontend controller the File relation has an empty object.

我看到该文件不在File_Live表中，所以我猜它没有发布，因此在前端控制器上找不到它.

I see that the file is not in the File_Live table, so i guess its not published and therefor its not found on the frontend controller.

如何从ModelAdmin发布文件关系?基本上，文件上传后应该自动发布.

How can i publish File relations from the ModelAdmin?Basically when a file is uploaded it should be automatically published.

我想如果我使用版本化的DataObjects，我仍然需要这样的东西: https://github.com/drzax/silverstripe-bits/tree/master/VersionedModelAdmin
在ModelAdmin上具有发布机制.

I guess if i use versioned DataObjects i would still need something like this: https://github.com/drzax/silverstripe-bits/tree/master/VersionedModelAdmin
to have publish mechanism on ModelAdmin.

或者SS4中内置了什么?还会将其降级到文件关系吗?

Or is there something builtin in SS4?Would this cascade down to File relations as well?

修改:关于版本化的DataObjects，SS4中有一个内置的发布按钮只需使用:

regarding versioned DataObjects there is a built in publish button in SS4just use:

private static $extensions = [
    Versioned::class,
];

private static $versioned_gridfield_extensions = true;

推荐答案

您可以将以下内容添加到DataObject中:

You can add the following to your DataObject:

private static $owns = ['FileRelationName'];

具有关系的示例:

private static $has_one = ['File' => File::class];
private static $owns = ['File'];

任何以此方式声明为拥有"的相关对象将与DataObject本身一起发布.

Any related object that is being declared as "owned" in this way will be published with the DataObject itself.
