Disable Result Cache (Redis) on Dev Env - Symfony2 - symfony

Question

I want to disable result caching while on the development enviroment.
I do not want to comment caching codes or remove them while on dev env.
Is there any way to disable caching while on dev env?
I'm using SNCRedisBundle & Predis for Symfony2 with Redis.
Sample single result codes:
$em = $this->container->get('doctrine')->getManager();
$predis = new \Snc\RedisBundle\Doctrine\Cache\RedisCache();
$predis->setRedis(new \Predis\Client());
$qb = $em->createQueryBuilder();
$qb
->select('s')
->from('CSSliderBundle:Slider', 's')
->where($qb->expr()->eq('s.title', ':title'))
->setParameter('title', $title);
$slider = $qb
->getQuery()
->useResultCache(true, 3600 * 1.5) // added this line
->setResultCacheDriver($predis)
->setResultCacheLifetime(86400)
->getOneOrNullResult();
And second question:
Is there any way to clear cache after insert / update with doctrine build-in? I know i can use lifecycleevents but i wonder if any other option available...

You don't need to inject result cache impl to doctrine each time. Just configure your snc_redis bundle like this:
snc_redis:
# other options here..
doctrine:
result_cache:
client: cache # your redis cahce_id connection
entity_manager: default # you may specify multiple entity_managers
namespace: "doctrine_result_cache_%kernel.environment%_"
After that, you can disable it for config_dev.yml
Enable caching for $query:
// public function useResultCache($bool, $lifetime = null, $resultCacheId = null)
$query->useResultCache(true, 3600 * 1.5);
