[TYPO3-mvc] Define a PID per object, not by configuration

[Adrien Crivelli]

Answering my own question. It's actually pretty easy once we figured out the
injection system in ExtBase:

1. Extends the class with your own and override whatever method you need,
eg:

class Tx_Newsletter_Persistence_BackendPidFriendly extends
Tx_Extbase_Persistence_Backend {
protected function
determineStoragePageIdForNewRecord(Tx_Extbase_DomainObject_DomainObjectInterface
$object = NULL) {
if ($object !== NULL &&
Tx_Extbase_Reflection_ObjectAccess::isPropertyGettable($object, 'pid')) {
$pid = Tx_Extbase_Reflection_ObjectAccess::getProperty($object, 'pid');
if (isset($pid)) {
return (int) $pid;
}
}

return parent::determineStoragePageIdForNewRecord($object);
}
}

2. Configure ExtBase to use it (in Configuration/TypoScript/setup.txt):


config.tx_extbase {

objects {

Tx_Extbase_Persistence_BackendInterface {

className = Tx_Newsletter_Persistence_BackendPidFriendly

}

}

}

That's it. More details available in the repository:
