[TYPO3-mvc] How to cope with anonymous FE user entries

[Thomas Hucke]

Hi all,

I write an extension (th_rating) to do ratings of any object.
Originally my model restricts any rating to be connected to a FE user.
No I reached a request to allow anonymous ratings ( 
http://forge.typo3.org/issues/34436 ).

How can I model that?
Obviously extbase needs a valid FE user to handle a create-action.
Everytime I call the CREATE action with "voter=0" the getErrorFlashMessage 
method is being called in my controller.

This is how I modeled the connection to FE user:

/**
  * The voter of this object
  *
  * @var Tx_Extbase_Domain_Model_FrontendUser
  * @lazy
  */
protected $voter;

/**
  * Sets the frontenduser of this vote
  *
  * @param Tx_Extbase_Domain_Model_FrontendUser $voter An object storage 
containing the frontenduser
  * @return void
  */
public function setVoter(Tx_Extbase_Domain_Model_FrontendUser $voter) {
  $this->voter = $voter;
}

/**
  * Returns the frontenduser of this vote
  *
  * @return Tx_Extbase_Domain_Model_FrontendUser The frontenduser of this 
vote
  */
public function getVoter() {
  if ($this->voter instanceof Tx_Extbase_Persistence_LazyLoadingProxy) {
   $this->voter = $this->voter->_loadRealInstance();
  }
  return $this->voter;
}


This is the CREATE-action:
/**
  * Creates a new vote
  *
  * @param Tx_ThRating_Domain_Model_Vote $vote A fresh vote object which has 
not yet been added to the repository
  * @return void
  * dontverifyrequesthash
  */
//http://localhost:8503/index.php?id=71&tx_thrating_pi1[controller]=Vote&tx_thrating_pi1[action]=create&tx_thrating_pi1[vote][rating]=1&tx_thrating_pi1[vote][voter]=1&tx_thrating_pi1[vote][vote]=1
public function createAction(Tx_ThRating_Domain_Model_Vote $vote) {
  //t3lib_utility_Debug::debug($vote,'Debug');
  if ($this->settings['allowAnonymous'] || 
$this->accessControllService->backendAdminIsLoggedIn() || 
$this->accessControllService->isLoggedIn($vote->getVoter())) {
   $matchVote = 
$this->voteRepository->findMatchingRatingAndVoter($vote->getRating(),$vote->getVoter());
   if (!($matchVote instanceof Tx_ThRating_Domain_Model_Vote) || 
!$this->voteValidator->isValid($matchVote)) {
    $vote->getRating()->addVote($vote);
    //persist newly added object to enable redirect to show action
    Tx_Extbase_Dispatcher::getPersistenceManager()->persistAll();
    $this->flashMessageContainer->add(Tx_Extbase_Utility_Localization::translate('error.vote.create.newCreated', 
'ThRating'));
   } else {
    $vote = $matchVote;
    $this->flashMessageContainer->add(Tx_Extbase_Utility_Localization::translate('error.vote.create.alreadyRated', 
'ThRating', t3lib_FlashMessage::NOTICE));
   }
  } else {
   $this->flashMessageContainer->add(Tx_Extbase_Utility_Localization::translate('error.vote.create.noPermission', 
'ThRating', t3lib_FlashMessage::ERROR));
  }

  $referrer = $this->request->getArgument('__referrer');
  $this->forward($referrer['actionName'],$referrer['controllerName'],$referrer['extensionName'],$this->request->getArguments());
}



Thanks in advance
Thomas
