TYPO3 9.5 Extbase plugin cache implementation
I am trying to get a cache working in my plugin.
In ext_localconf.php
if (!is_array($GLOBALS['TYPO3_CONF_VARS']['SYS']['caching']['cacheConfigurations']['myextension'])) {
$GLOBALS['TYPO3_CONF_VARS']['SYS']['caching']['cacheConfigurations']['myextension'] = ;}
if (!isset($GLOBALS['TYPO3_CONF_VARS']['SYS']['caching']['cacheConfigurations']['myextension']['frontend'])) {
$GLOBALS['TYPO3_CONF_VARS']['SYS']['caching']['cacheConfigurations']['myextension']['frontend'] = 'TYPO3\CMS\Core\Cache\Frontend\StringFrontend';}
if (!isset($GLOBALS['TYPO3_CONF_VARS']['SYS']['caching']['cacheConfigurations']['myextension']['options'])) {
$GLOBALS['TYPO3_CONF_VARS']['SYS']['caching']['cacheConfigurations']['myextension']['options'] = ['defaultLifetime' => 0];}
if (!isset($GLOBALS['TYPO3_CONF_VARS']['SYS']['caching']['cacheConfigurations']['myextension']['groups'])) {
$GLOBALS['TYPO3_CONF_VARS']['SYS']['caching']['cacheConfigurations']['myextension']['groups'] = ['pages'];}
In my controller action :
$cacheIdentifier = 'topic' . $topic->getUid();
$cache = GeneralUtility::makeInstance(CacheManager::class)->getCache('myextension');
$result = unserialize($cache->get($cacheIdentifier));
if ($result !== false ) {
DebuggerUtility::var_dump($result);
} else {
$result = $this->postRepository->findByTopic($topic->getUid(), $page, $itemsPerPage);
$cache->set($cacheIdentifier, serialize($result), ['tag1', 'tag2']);
DebuggerUtility::var_dump($result);
}
The first time the page with the action gets loaded all is ok and the entry has been made in de database (cf_myextension and cf_myextension_tags}.
But the 2nd time the cache gets loaded and I get an error. Even DebuggerUtility::var_dump($result); does not work:
Call to a member function map() on null
in ../typo3/sysext/extbase/Classes/Persistence/Generic/QueryResult.php line 96
*/
protected function initialize()
{
if (!is_array($this->queryResult)) {
$this->queryResult = $this->dataMapper->map($this->query->getType(), $this->persistenceManager->getObjectDataByQuery($this->query));
}
}
/**
A normal var_dump works and spits out the cache entry. What is the problem? Do I forget something? Can't a QueryResult together with some other variables not be stored as an array in the cache? I also tried VariableFrontend cache, which produced the same error.
