[TYPO3-mvc] Auto-Updating related objects

Hi,

how about moving part of that logic into your domain models?

public function getRoles() {
   if (!$this->roles->count()) {
     $objectManager = 
t3lib_div::makeInstance('Tx_Extbase_Persistence_ObjectManager');
     $service = 
$objectManager->get('Tx_YourExt_Domain_Service_AccountService');
     return $service->getRolesByAccount($this);
   }
   return clone $this->roles;
}


Once DI for domain models is fully implemented (patches are currently 
reviewed on gerrit) you could also use DI to inject your 
service/repository or whatever you like to trigger to get your roles 
from the REST api. But please note that when using DI to f.e. inject the 
objectManager/Service/Repository you might no longer be able to debug 
the domain models with current debug methods due to the nested relations 
on those objects (resulting in a white page/server error).
