TYPO3: get all FE users - typo3

Question

I am trying to create a user management module. I would like to get all FE users.
This is my Controller:
/**
* #var \TYPO3\CMS\Extbase\Domain\Repository\FrontendUserRepository
* #inject
*/
protected $feUserRepository;
then I use:
$users = $this->feUserRepository->findAll();
$this->view->assign('users', $users);
but all I get is an empty object.
EDIT:
for some reason
$this->feUserRepository->findByUId(1);
does work but findAll() not...

Answer 1

This is because extbase will silently disable the respectStoragePage setting on the querySettings for a findByUid($uid) call.
So, you have two options:
Provide the correct storage pid in the TypoScript configuration of your plugin (plugin.tx_myextension.persistence.storagePid). This way, you will find every frontenduser that is stored on the given page.
You could implement your own FrontendUserRepository that extends the repository from extbase but disables the respectStoragePage for all calls (this way you'll get every frontendUser regardless of the page the record is stored on). Here is how you do it:
use TYPO3\CMS\Extbase\Domain\Repository\FrontendUserRepository as ExtbaseFrontendUserRepository;
class FrontendUserRepository extends ExtbaseFrontendUserRepository
{
/**
* Disable respecting of a storage pid within queries globally.
*/
public function initializeObject()
{
$defaultQuerySettings = $this->objectManager->get(\TYPO3\CMS\Extbase\Persistence\Generic\Typo3QuerySettings:class);
$defaultQuerySettings->setRespectStoragePage(false);
$this->setDefaultQuerySettings($defaultQuerySettings);
}
}
In your Controller you then inject your FrontendUserRepository. Then you should do the same for the FrontendUser Model and tell extbase afterwards that you are using the fe_users table for your Model:
config.tx_extbase {
persistence {
classes {
Vendor\MyExtension\Domain\Model\FrontendUser {
mapping {
tableName = fe_users
}
}
}
}
}
