October CMS specify attachment_type for system_files table

Question

for the attachment_type field in the system_files table, a string with the class name is automatically generated. How to set specify class string?

looks like this now:

public $attachOne = [
    'main_photo' => [
        'System\Models\File',
        'delete' => true,
    ]
];

Answer 1

I'm assuming here, but I guess you're not wanting to have the full class stored in in the attachment_type column of the system_files table.

What you can do is define a morph map in the boot() method of your plugin's Plugin.php file.

So if you had a plugin in the October\Shop namespace, with a Product model you could do this.

// Plugin.php

<?php

namespace October\Shop;

use System\Classes\PluginBase;
use October\Rain\Database\Relations\Relation;

class Plugin extends PluginBase
{
    public function boot()
    {
        Relation::morphMap([
            'product' => \October\Shop\Models\Product::class,
        ]);
    }

    /** The rest of your plugin.php file **/
}

You can read about this in the docs.
