How to extend powermail data models in version 12?

[kitzberger]

I'm trying to figure out how to properly extend the data models in TYPO3 12 and EXT:powermail 12.

Since TYPO3\CMS\Extbase\Container\Container is gone with TYPO3 12 the respective section of this extensions documentation isn't working anymore: https://github.com/in2code-de/powermail/blob/master/Documentation/ForDevelopers/AddNewFieldProperties.md

Neither is the example in EXT:powermailextended. The latest PR (einpraegsam/powermailextended#9) has never been merged and isn't not compatible with version 12 anyway.

Here's what I found out so far.

Configuration/Extbase/Persistence/Classes.php should look like this:

<?php
declare(strict_types=1);
return [
    \Me\MyExtension\Domain\Model\Page::class => [
        'tableName' => 'tx_powermail_domain_model_page',
    ],
    \Me\MyExtension\Domain\Model\Field::class => [
        'tableName' => 'tx_powermail_domain_model_field',
    ],
];

ext_localconf.php like this:

<?php
defined('TYPO3') || die('Access denied.');
$GLOBALS['TYPO3_CONF_VARS']['SYS']['Objects'][\In2code\Powermail\Domain\Model\Page::class] = [
    'className' => \Me\MyExtension\Domain\Model\Page::class,
];
$GLOBALS['TYPO3_CONF_VARS']['SYS']['Objects'][\In2code\Powermail\Domain\Model\Field::class] = [
    'className' => \Me\MyExtension\Domain\Model\Field::class,
];

Caution: in case of overwriting both Page and Field the relationship between them both needs to be tweaked too, to prevent some weird endless loop:

<?php
namespace Me\MyExtension\Domain\Model;
class Page extends \In2code\Powermail\Domain\Model\Page
{
    /**
     * @var \TYPO3\CMS\Extbase\Persistence\ObjectStorage<\Me\MyExtension\Domain\Model\Field>
     */
    protected $fields = null;
}

I'd really appreciate some feedback of other developers on this matter and together find a solid solution.

For me Configuration/Extbase/Persistence/Classes.php

`<?php
declare(strict_types = 1);

return [

\In2code\Powermail\Domain\Model\Form::class => [
    'subclasses' => [           
        'formClass' => \Vendor\My\Domain\Model\Form::class,
    ]        
],

\In2code\Powermail\Domain\Model\Page::class => [
    'subclasses' => [           
        'pageClass' => \Vendor\My\Domain\Model\Page::class,
    ]        
],

\In2code\Powermail\Domain\Model\Field::class => [
    'subclasses' => [           
        'fieldClass' => \Vendor\My\Domain\Model\Field::class,
    ]        
],

\Vendor\My\Domain\Model\Form::class => [
    'tableName' => 'tx_powermail_domain_model_form'
],

\Vendor\My\Domain\Model\Page::class => [
    'tableName' => 'tx_powermail_domain_model_page'
],

\Vendor\My\Domain\Model\Field::class => [
    'tableName' => 'tx_powermail_domain_model_field'
]

]`

I see it in vendor/typo3/cms-extbase/Classes/Persistence/Generic/Mapper/DataMapFactory.php

But I have no lunch my model also I have no variables in my Fluid. Also try setup dependencies with composer.json and ext_emconf.php

For News this approach works fine
