showAction : finding fe_user entry by username instead of uid - typo3

I created my own (Typo3 6.2) extension with the Extension Builder to extend fe_users and all is working fine but I would like to be able to use the showAction based on the username instead of the uid of the user.
The goal is simply to be able to call the controller on the frontend like this:
my.domain.com/users?tx_crilcq_crilcqmember[username]=johndoe&tx_crilcq_crilcqmember[action]=show
instead of this:
my.domain.com/users?tx_crilcq_crilcqmember[member]=2&tx_crilcq_crilcqmember[action]=show
At first I thought that I had to modify the extended repository (class MemberRepository extends \TYPO3\CMS\Extbase\Persistence\Repository) but it seems that it is used for requests returning an array of entries and not to reference a single instance. Don't know if I'm right about this but my feeling is that the thing I need to modify is somewhere else.
Any clue someone?

An Extbase repository has magic methods findBy[property], findOneBy[property] and countBy[property], that returns/counts objects by the given property.
You can change your show action as shown below:
/**
* #param string $username
* #return void
*/
public function showAction($username) {
$user = $this->memberClassRepository->findOneByUsername($username);
$this->view->assign('user', $user);
}

How to change the position of a column in the TYPO3 TCA?

I want to move a column from one tab to another. Is there a better way than to rewrite the types definition manually which is not very reliant in regard to extension updates changing the TCA?
It's not 100% fail safe, since there still might be extensions messing things up, but the closest you can get will be to make use of the ExtTablesInclusionPostProcessing event and put addToAllTCAtypes into the invoke method, since this will not just add new fields but even put existing fields to another tab:
<?php
declare(strict_types=1);
namespace Vendor\Extension\EventListener;
use TYPO3\CMS\Core\Utility\ExtensionManagementUtility;
/**
* Class ExtTablesInclusionPostProcessing
*/
class ExtTablesInclusionPostProcessing
{
/**
* Function which may process data created / registered by extTables
* scripts (f.e. modifying TCA data of all extensions)
*
* #param AfterTcaCompilationEvent $event
*/
public function __invoke(AfterTcaCompilationEvent $event): void
{
ExtensionManagementUtility::addToAllTCAtypes('tt_content', 'fieldname', '', 'after:fieldname_in_the_other_tab');
}
}
To remove the existing field before, you could make use of this trick:
https://stackoverflow.com/a/59179916/2333754
And finally to be on the safer side you could make sure that other extensions are loaded before your own extension by putting them into the suggest section of your composer.json.
With installation of extension tcabuilder it is possible to do simple changes in the TCA.

Typo3: Controller action with hidden record as its parameter

I am currently trying to get a extension working in Typo3 v10, which enables the user to show, edit, update, disable and enable other user accounts.
Unfortunately, I am running into the issue that I cannot use disabled users as arguments for the actions:
/**
* Save user changes
*
* #param \Company\MyExtension\Domain\FeUser $feuser
* #return void
*/
public function updateAction(\Company\MyExtension\Domain\FeUser $feuser): void {}
It would resulting in the error following error:
Object of type \Company\MyExtension\Domain\FeUser with identity "3" not found.
From what I have gathered, extbase does not rely on the repository's default query settings to create the objects but instead uses PersistenceManager::createQueryForType to get the query settings via QueryFactory::create. This is an issue also listed in a few bug reports.
There's a suggestions as to how to use a custom QueryFactory to set different default QuerySettings for my extension, however this does not seem to work in Typo3 v10 anymore, at least my custom QueryFactory isn't being used after registering it... Also, if this were to work, wouldn't it use the new QueryFactory for all objects instantiated through a controller action and not just this extension?
How can I properly handle hidden users my extension with Typo3 v10.4?
P.S. Another suggestion was to fetch object early through initializeAction, but this only works well if it is about the unmodified model and not when setting new values for the object, as it would just load the database values in the end...
Checkout the extension "news" how it is handled here:
if ($news === null || $this->settings['isShortcut']) {
$previewNewsId = ((int)$this->settings['singleNews'] > 0) ? $this->settings['singleNews'] : 0;
if ($this->request->hasArgument('news_preview')) {
$previewNewsId = (int)$this->request->getArgument('news_preview');
}
if ($previewNewsId > 0) {
if ($this->isPreviewOfHiddenRecordsEnabled()) {
$news = $this->newsRepository->findByUid($previewNewsId, false);
} else {
$news = $this->newsRepository->findByUid($previewNewsId);
}
}
}

I am assuming you need the URL as well. I gave an answer here if you wanna take a look.
Show, edit and update hidden records in FrontEnd (TYPO3)
You can adjust it to your own needs as well.

Retrieving the BackendUser from BackendUserAuthentication

I'm trying to develop an extension that adds a Button to the ClearCache menu in the TYPO3 Backend. In a large installation with multiple domains, non-admin users need a button to clear the page cache for their domain, but only of those pages that they have access to. The default options.clearCache.pages = 1 instead flushes the whole Frontend Cache of the installation.
I've gotten so far as to calling a method in a custom class ClearCacheHook, that implements \TYPO3\CMS\Backend\Toolbar\ClearCacheActionsHookInterface.
I next need to get a list of all page uids the BackendUser has access to, which is done with $backendUser->getDbMountPoints(). All the docs speak of a global variable $BE_USER, but this isn't set for me. I have a $GLOBALS['BE_USER'], but that is of the class BackendUserAuthentication.
I can't figure out how to resolve the BackendUser from the BackendUserAuthentication. Theres the BackendUser uid in the object so I tried initializing a TYPO3\\CMS\\Beuser\\Domain\\Repository\\BackendUserRepository via the ObjectManager, but that fails.
I'll focus on the more specific tasks: Create an instance of BackendUserRepository and create an instance of BackendUser from uid.
You might have a look at the UsernameViewHelper.php class of be_log in the TYPO3 core.
specifically this:
use TYPO3\CMS\Core\Utility\GeneralUtility;
use TYPO3\CMS\Extbase\Domain\Repository\BackendUserRepository;
use TYPO3\CMS\Extbase\Object\ObjectManager;
...
$objectManager = GeneralUtility::makeInstance(ObjectManager::class);
$backendUserRepository = $objectManager->get(BackendUserRepository::class);
/** #var \TYPO3\CMS\Extbase\Domain\Model\BackendUser $user */
$user = $backendUserRepository->findByUid($uid);
If there is something, I don't find in the documentation, I sometimes look at existing extensions. A good candidate is the news extensions. Other good candidates are, of course, the TYPO3 source code.

How to make extbase extension recognize storage page from plugin?

In an extbase extension built with extension builder on TYPO3 6.1.7, I haven't set any storagePid via Typoscript.
But I have set the "Record Storage Page" in the plugin:
I would expect that it would now only fetch records from this page.
But it doesn't, it just returns all items from that table.
How do I make the extension recognize the setting from the plugin?
Or (if it's supposed to do that out of the box) how do I find out why it doesn't?
I did a lot of research when my extension's frontend plugin (TYPO3 7.6.4) refused to use the 'pages' field of the plugin ("Record Storage Page"), so I would like to share my findings:
My extension's name is 'tx_dhsnews', my plugin's name is 'infobox'
setRespectStoragePage must be set to true (default): $query->setRespectStoragePage(TRUE)
In the typoscript-setup, the plugin-specific storagePid plugin.tx_dhsnews_infobox.persistence.storagePid MUST NOT be present at all! Not even with an empty value! Else the 'pages'-field will not be respected!
That's all. The Extensions Builder just created a typoscript-setup with the storagePid for the specific plugin 'infobox' set to nothing. That resulted in the plugin not respecting the 'pages' - field.
It's no problem to set the storagePid on extension-level (e.g. 'tx_dhsnews..persistence.storagePid'), the value will be merged with the value(s) given in 'pages' ("Record Storage Page"), but as soon the plugin-specific tx_[extension]_[plugin].persistence.storagePid exists in the typoscript, it will overrule everything else!
Hope this will help somebody to save some time + nerves
Add the following code to your repository
namespace <Vendor>\<Extkey>\Domain\Repository;
class ExampleRepository extends \TYPO3\CMS\Extbase\Persistence\Repository {
// Example for repository wide settings
public function initializeObject() {
/** #var $defaultQuerySettings \TYPO3\CMS\Extbase\Persistence\Generic\Typo3QuerySettings */
$defaultQuerySettings = $this->objectManager->get('TYPO3\\CMS\\Extbase\\Persistence\\Generic\\Typo3QuerySettings');
// add the pid constraint
$defaultQuerySettings->setRespectStoragePage(TRUE);
}
// Example for a function setup changing query settings
public function findSomething() {
$query = $this->createQuery();
// add the pid constraint
$query->getQuerySettings()->setRespectStoragePage(TRUE);
// the same functions as shown in initializeObject can be applied.
return $query->execute();
}
}

I actually modified my MVC controller to achieve a record filtering depending on the actual page(storagePid==page.id).. looked like this:
use TYPO3\CMS\Extbase\Mvc\Controller\ActionController;
class MyMVCController extends ActionController {
protected function initializeAction() {
parent::initializeAction();
//fallback to current pid if no storagePid is defined
$configuration = $this->configurationManager->getConfiguration(\TYPO3\CMS\Extbase\Configuration\ConfigurationManagerInterface::CONFIGURATION_TYPE_FRAMEWORK);
if (empty($configuration['persistence']['storagePid'])) {
$currentPid['persistence']['storagePid'] = GeneralUtility::_GP('id');
$this->configurationManager->setConfiguration(array_merge($configuration, $currentPid));
}
[..]
I used the solution by http://wiki.t3easy.de/ and modified the value of the storagePid cause i developed a backend module.
His tscript example didnt worked for me..
Also an article by Thomas Deuling was interesting for the topic..
but i still dont get the whole connection into my mind.. wanna go back to symfony xD
edit: for the modification of the repo queries also this article looked interesting:

TYPO3 extbase - get "uid" of non persisted object

Just started out with the frst extbase extension. In localconf I added these actions: 'list, new, show, create, edit'.
Default was that "create" redirected to "list" with no arguments, and that worked fine right after creation of the extension.
$this->redirect('list'); // <- this works if used
But instead of redirecting to "list" I would like to redirect to "show" to display the newly added priceFormCalc. A collegue helped me to acomplish this using persist.
Below is the code and it works. But reading on the net it seem that it should not be best practice to run persist. It should be doable to call the action show without manually persisting first.
So question is: Is this the correct way to do it, or is there a more "ext base" way show a newly created record?
public function createAction(\TYPO3\OgNovomatrixpricecalc\Domain\Model\PriceCalcForm $newPriceCalcForm) {
$this->priceCalcFormRepository->add($newPriceCalcForm);
$this->flashMessageContainer->add('Your new PriceCalcForm was created.');
// workaround - or the right way?
$persistenceManager = \TYPO3\CMS\Core\Utility\GeneralUtility::makeInstance('Tx_Extbase_Persistence_Manager');
$persistenceManager->persistAll(); // <- save i database
$uid = $newPriceCalcForm->getUid(); // <- get UID of newly saved record
// do redirect using uid of newly created priceCalcForm
$this->redirect('show',Null,Null, array('priceCalcForm' => $uid));
}

You can persist the current state and then get the uid. Inject the configuration manager (TYPO3 6.x way):
/**
* persistence manager
*
* #var \TYPO3\CMS\Extbase\Persistence\PersistenceManagerInterface
* #inject
*/
protected $persistenceManager;
Then use
$this->persistenceManager->persistAll();
to apply all changes. Then you can pass your object (or only the uid) to the action.
