How to automaticly publish images in silverstripe dataextension - php

Question

I was trying to add an uploadfield to a Custom DataExtension and got the Image field working. However the image i uploaded stays in concept mode, and i have to go to the File tab to publish it. I tried to use the code provided in the Silverstripe documentation but this only seems to work on regular pages. I found a question similar to mine:How to automaticaly publish files uploaded to a dataobject in Silverstripe model admin however this only seems to work on DataObjects.
This is my current code:
<?php
use SilverStripe\Forms\LiteralField;
use SilverStripe\Forms\TextField;
use SilverStripe\Forms\FieldList;
use SilverStripe\Forms\HTMLEditor\HTMLEditorField;
use SilverStripe\AssetAdmin\Forms\UploadField;
use SilverStripe\Assets\Image;
use SilverStripe\Assets\Storage\AssetStore;
use SilverStripe\Versioned\Versioned;
use SilverStripe\ORM\DataExtension;
class CustomSiteConfig extends DataExtension
{
private static $db = [
];
private static $has_one = [
'Logo' => Image::class
];
private static $owns = [
'Logo'
];
private static $extensions = [
Versioned::class,
];
private static $versioned_gridfield_extensions = true;
public function updateCMSFields(FieldList $fields)
{
$fields->addFieldToTab("Root.Header", LiteralField::create("","<h1>Header</h1>"));
$fields->addFieldToTab("Root.Header", UploadField::create('Logo', 'Logo'));
}
}
Does anyone know a solution?

There's currently a bug that prevents "owned" records to be published if the owning dataobject is not versioned.
I think you're experience this bug, since SiteConfig is not versioned and thus won't publish owned files/images when it's being saved.
Until this bug has been resolved, you could use an onAfterWrite hook in your extension to publish the file:
public function onAfterWrite()
{
if ($this->owner->LogoID) {
$this->owner->Logo()->publishSingle();
}
}
