I made a custom admin page and i am saving some configuration fields there and then am getting a notification from magento that i need to flush the cache. Is there any way to do that from the module itself? maybe put a hook where i save the config?


You can inject \Magento\Framework\App\CacheInterface as dependency and assign it to $_cacheManager in your constructor or get it from de $context (if you have) and then after save changes clean the related cache that way:


You could find a complete implementation in Catalog\Product\Model

I guess you could use the "get" method of the ObjectManager to get the cache instance too, but I'm not sure if is a good practice.

  • This is great! 10x I'm just not sure about which tag i am supposed to use.. – Omry Zobel Dec 27 '15 at 10:30
  • It depends on what your configuration chances will affect, so you can start with config i guess (i don't remember the actual name) – MauroNigrele Dec 27 '15 at 11:08
  • I know for a fact it's config...but i'm not sure how to find out the name, the clean function always returns true, so that's not a good indication. I tried 'CONFIG', tried get all type names from \Magento\Framework\App\Cache\TypeListInterface ... and still didn't work. – Omry Zobel Dec 27 '15 at 11:12
  • I even tried calling \Magento\Backend\Controller\Adminhtml\Cache\FlushAll and then there is a notification that i flushed the cache..but still on the cache management page the cache is invalidated. – Omry Zobel Dec 27 '15 at 11:37
  • Can you check on debug.log if perhaps another event invalidate the cache after your cleanup? – MauroNigrele Dec 27 '15 at 11:41

go into magento root folder using command

sudo php bin/magento cache:clean

run above command.

I hope this will help you.
